C Interview/viva Questions

               C Interview/viva Questions.....   

 1

What will be output if you will execute following c code?

#include<stdio.h>

int main(){

    int i;

    for(i=0;i<5;i++){

         int i=10;

         printf(" %d",i);

         i++;

    }

    return 0;

}

(A)	10 11 12 13 14
Correct	10 10 10 10 10
(C)	0 1 2 3 4
Wrong	Compilation error

Explanation:

Default storage class of local variable is auto. Scope of auto variables are block in which it has been declared. When program control goes out of the scope auto variables are dead. So variable i which has been declared inside for loop has scope within loop and in each iteration variable i is dead and re-initialized. Note: If we have declared two variables of same name but different scope then local variable will have higher priority.

2

What will be output if you will execute following c code?

#include<stdio.h>

int main(){

    register a,b,x;

    scanf("%d %d",&a,&b);

    x=a+~b;

    printf("%d",x);

    return 0;

}

(A)	0
(B)	It will be difference of a and b
(C)	It will be addition of a and b
Correct	Compilation error

Explanation:

Register variables are stored in CPU. So it has not memory address. Hence it is incorrect to write &a.

3

What will be output if you will execute following c code?

#include<stdio.h>

auto int a=5;

int main(){

    int x;

    x=~a+a&a+a<<a;

    printf("%d",x);

    return 0;

}

(A)	5
Wrong	0
(C)	153
Correct	Compilation error

Explanation:

We cannot declare auto variable outside of any function since it auto variables gets are created (i.e. gets memory) at run time.

4

What will be output if you will execute following c code?

#include<stdio.h>

int main(){

    register int a,b;

    int c;

    scanf("%d%d",&a,&b);

    c=~a + ~b + ++a + b++;

    printf(" %d",c);

    return 0;

}

//User input is: 1 2

(A)	-1
(B)	0
(C)	1
Correct	Compilation error

Explanation:

Register variables are stored in CPU. So it has not memory address. Hence it is incorrect to write &a.

5

What will be output if you will execute following c code?

#include<stdio.h>

int main(){

    int arr[3]={10,20,30};

    int x=0;

    x = ++arr[++x] + ++x + arr[--x];

    printf("%d ",x);

    return 0;

}

(A)	22
(B)	23
Correct	43
(D)	44

Explanation:

In Turbo C 3.0 and 4.5 compilers Output: 43 Consider on expression: = ++arr[++x] + ++x + arr[--x] //x = 0 + 1 = ++arr[++x] + ++x + arr[--x] //x = 1 + 1 = ++arr[++x] + ++x + arr[--x] //x = 2 - 1 = ++arr[1] + 1 + arr[1] //x = 1 = ++arr[1] + 1 + arr[1]  //arr[1] = 20+1 = arr[1] + 1 + arr[1] //arr[1] = 21 = 21 + 1 + 21 = 43 In Linux GCC complier Output: 44 Consider on expression: = ++arr[++x] + ++x + arr[--x] //x = 0 + 1 = ++arr[1] + ++x + arr[--x] ////x = 1 + 1 = ++arr[++x] + 2 + arr[--x] //x = 2 - 1 = ++arr[1] + 2 + arr[1] //arr[1] = 20+1 = arr[1] + 1 + arr[1] //arr[1] = 21 = 21 + 2 + 21 = 44

6

What will be output if you will execute following c code?

#include<stdio.h>

int main(){

    int a[]={10,20,30,40};

    int i=3,x;

    x=1*a[--i]+2*a[--i]+3*a[--i];

    printf("%d",x);

    return 0;

}

(A)	30
Correct	60
(C)	90
(D)	Compilation error

Explanation:

In Turbo C 3.0 and 4.5 compilers Output: 60 Consider on expression: = 1 * a[--i] + 2 * a[--i] + 3 * a[--i] //i = 3 - 2 = 1 * a[--i] + 2 * a[--i] + 3 * a[--i] //i = 2 - 1 = 1 * a[--i] + 2 * a[--i] + 3 * a[--i] //i = 1 - 1 = 1 * a[0] + 2 * a[0] + 3 * a[0] //i = 0 = 1 * 10 + 2 * 10 + 3 * 10 //a[0] = 10 = 10 + 20 + 30 = 60 In Linux GCC complier Output: 90 Consider on expression: = 1 * a[--i] + 2 * a[--i] + 3 * a[--i] //i = 3 - 2 = 1 * a[--i] + 2 * a[--i] + 3 * a[--i] //i = 2 - 1 = 1 * a[1] + 2 * a[1] + 3 * a[--i] //i = 1 - 1 = 1 * a[1] + 2 * a[1] + 3 * a[0] = 1 * 20 + 2 * 20 + 3 * 10 = 20 + 40 + 30 = 90

7

What will be output if you will execute following c code?

#include<stdio.h>

int main(){

    static int a[][2][3]={0,1,2,3,4,5,6,7,8,9,10,11,12};

    int i=-1;

    int d;

    d=a[i++][++i][++i];

    printf("%d",d);

    return 0;

}

(A)	9
Correct	10
(C)	11
(D)	Compilation error

Explanation:

= a[i++][++i][++i] //i = -1 + 1 = a[i++][++i][++i] //i = 0 + 1 = a[1][1][1] //i = 1 + 1 = 10

8

What will be output if you will execute following c code?

#include<stdio.h>

int f(int);

int main(){

    int i=3,val;

    val=sizeof (f(i)+ +f(i=1)+ +f(i-1));

    printf("%d %d",val,i);  

    return 0; 

}

int f(int num){

        return num*5;

}

Correct	2 3
(B)	4 3
(C)	3 2
(D)	Compilation error

Explanation:

Turbo C 3.0 and Turbo C 4.5 compiler: 2 3 Linux GCC complier: 4 3 Any expression inside sizeof operator is never changed the value of the any variable. So value of variable i will remain 3. After the evaluation of expression inside sizeof operator we will get an integer value. So value of variable val will be sizeof int data type.

What will be output if you will execute following c code?

#include<stdio.h>

int main(){

    int x,a=3;

    x=+ +a+ + +a+ + +5;

    printf("%d  %d",x,a);

    return 0;

}

(A)	10 3
Correct	11 3
(C)	10 5
(D)	Compilation error

Explanation:

Consider on expression: + +a Here both + are unary plus operation. So = + +a+ + +a+ + +5; = + +3+ + +3+ + 5 = 3+ 3+ 5 = 11 Note: Increment operator ++ cannot have space between two plus symbol.

What will be output if you will execute following c code?

#include<stdio.h>

int main(){

    int num,i=0;

    num=-++i+ ++-i;

    printf("%d",num);

    return 0;

}

(A)	0
(B)	1
(C)	-2
Correct	Compilation error

Explanation:

After operation of any operator on operand it returns constant value. Here we are performing unary minus operator on variable i so it will return a constant value and we can perform ++ operation on constant.

What will be output if you will execute following c code?

#include<stdio.h>

int main(){

    int num,a=5;

    num=-a--+ +++a;

    printf("%d  %d",num,a);

    return 0;

}

(A)	1 5
(B)	-1 6
(C)	1 6
Correct	0 5

Explanation:

= -a--+ +++a = -a-- + + ++a = -a-- + + ++a = -6 + + 6 //a = 6 -1 = -6 + 6 //a = 5 = 0

    int x,a=2;

    x=++a,++a,a++;

    printf("%d  %d",x,a);

    return 0;

}

(A)	5 5
Correct	3 5
(C)	4 5
(D)	5 4

Explanation:

x = ++a, ++a, a++ x = 3, ++a, a++ // a = 2 + 1 x = 3, ++a, a++ // = operator has higher precedence than comma operator x = 3, ++a, a++ // a = 3 + 1 x = 3, 4, a++  x = 3, 4, 4 // a = 4 + 1 x = 3 // a = 5

14

What will be output if you will execute following c code?

#include<stdio.h>

int main(){

    int x,i=2;

    x=~-!++i;

    printf("%d",x);

    return 0;

}

(A)	-2
Correct	-1
(C)	0
(D)	1

Explanation:

= ~-!++i = ~-!3 //i = 2 + 1 = ~-0 //!3 = 0 = ~0 //-0 = 0 = -(0 + 1) //~ is 1's complement operator. = -1

What will be output if you will execute following c code?

#include<stdio.h>

int main(){

    static double *p,*q,*r,*s,t=5.0;

    double **arr[]={&p,&q,&r,&s};

    int i;

    *p=*q=*r=*s=t;

    for(i=0;i<4;i++)

        printf("%.0f  ",**arr[i]);

    return 0;

}

(A)	5 5 5 5 5
(B)	5 6 7 8 9
(C)	Infinite loop
Correct	Run time error

What will be output if you will execute following c code?

#include<stdio.h>

int main(){

    float x;

    x=0.35==3.5/10;

    printf("%f",x);

    return 0;

}

Correct	0.000000
(B)	1.000000
(C)	0.350000
(D)	Compilation error

Explanation:

Turbo C 3.0 and Turbo C 4.5 compiler: Output: 0.000000 3.5/10 is little greater than .35 Linux GCC compilers: Output: 1.000000 Note: == is logic operator. It returns 1 if both operands are equal otherwise it returns 0.

#include<stdio.h>

int main(){

    int arr[]={6,12,18,24};

    int x=0;

    x=arr[1]+(arr[1]=2);

    printf("%d",x);

    return 0;

}

Correct	4	\
(B)	8
(C)	14
(D)	Compilation error

Explanation:

= arr[1] + (arr[1] = 2) //arr[i] = 2 = arr[1] + arr[1] = 2 + 2 = 4

18

What will be output if you will execute following c code?

#include<stdio.h>

int sq(int);

int main(){

    int a=1,x;

    x=sq(++a)+sq(a++)+sq(a++);

    printf("%d",x);

return 0;

}

int sq(int num){

    return num*num;

}

(A)	15
(B)	16
Correct	17
(D)	18

Explanation:

= sq(++a) + sq(a++) + sq(a++) //a= 1 + 1 = sq(2) + sq(2) + sq(a++) //a = 2 + 1 = sq(2) + sq(2) + sq(3)  //a = 3 + 1 = 4 + 4 + 9 = 17 Note: Pre-increment fist increment then assign while post increment operator first assign then increment.

19

What will be output if you will execute following c code?

#include<stdio.h>

int main(){

    printf("%c",*"abcde");

return 0;

}

(A)	acbcd
(B)	e
Correct	a
(D)	NULL

Explanation:

String constant "abcde" will return memory address of first character of the string constant. *"abcde" will return the first character of string constant.
