C - Programming ( Output based - Loop )

Which of the following is the correct output for the program given below.

#include <stdio.h>

void main()

{

int arr[5],i=-1,z;

while(i<5)

arr[i]=++i;

for(i=0;i<5;i++)

printf (“ %d”,arr[i]);

}

• 0 1 2 3 4

• 0 -1 -2 -3 -4

• -1 0 1 2 3 4

• 1 2 3 4 5

What will be the output of following prog . ?

#include <stdio.h>

void main()

{

int arr[]= {0,1,2,3,4};

int i, *p;

for(p=arr, i=0;p+i<=arr+4;p++,i++)

printf(“%d”,*(p+i));

}

• 0,2,4

• 0,1,2

• 0,2,3

• 2,3,4

which of the following statements is correct :

#include <stdio.h>

int main()

{

int i,x;

for(i=1;i<=(9%2 +i); i++)

{

x=(i*3 + i*2)/I;

printf("%d",x);

}

}

• The code prints output as 5 10

• The code prints output as 5 5 5 5

• The code prints 5 infinite numbers of times

• The code prints 20 infinite numbers of times

What will be the output of following prog . ?

#include <stdio.h>

void main()

{

static int arr[] ={2,3,4,5,6};

int i;

for(i=5;i>0;)

printf(“%d”,arr[--i]);

}

• 6 5 4 3 2

• 2 3 4 5 6

• 5 4 3 2 0

• no output

The function test is coded as follows:

int test(int num)

{

int m,n=0;

while(num)

{

m=num%10;

if(m%2)

n=n+1;

num=num/10;

}

return(n);

}

What will be the values of x and y when the following statements are executed?

int x= test(135);

int y == test(246);

• 0,0

• 0,3

• 3,0

• 3,3

Which of the following is the correct output for the program given below.

#include <stdio.h>

while(*p!='\0') ++*p++;

printf("%s %s",p,p1);

}

• hai friends

• ibj!gsjfoet

• ibj!gsjfoet hai friends

• Error
