Guess the output of the following code:

#include<stdio.h>

int main() {

char str[]="Hello"

char *ptr=str;

ptr+=3;

printf("%s", ptr);

return 0;

}

• Hello

• lo

• Hel

• llo

what's wrong with this code?

#include<stdio.h>

void main() {

int n=5;

int arr[n];

for(int i=1;i<=n; i++)

arr[i] = i;

printf("%d",arr[n]);

}

• Variable-sized array declaration

• Array index out of bound

• Missing return statement

• All of these

Operator in pointer is referred as

this code will give the output as -----------

#include<stdio.h>

int main(){

int i = 1;

do{

printf("%d",i);

i++;

if(i>3) break;

} while(1);

return 0;

}

An array is a collection of

• different data types scattered throughout memory

• the same data type scattered throughout memory

• the same data type placed next to each other in memory

• different data types placed next to each other in memory

find the output of the following code:

#include<stdio.h>

int main()

{

int x=15;

printf("\n%d%d",x<30,x=20);

}

correct the following code:

int main()

{

int tag = 0,code = 1;

if(tag==0)

(code>1? printf("\nHello")? printf("\nHi"));

else

printf("\nHello Hi ! ! ");

}

find the output for the following

#include<stdio.h>

int main(){

int num[26], temp;

num[0] = 100;

num[25] = 200;

temp = num[25];

num[25] = num[0];

num[0]=temp;

printf("\n%d%d", num[0],num[25]);

}

• 100, 100

• 200, 100

• 100, 200

• 200, 200

what is the output of the following code:

#include<stdio.h>

int main()

{

int sub[50], i;

for(i=0; i <=48; i++);

{

sub[i] = i%4;

printf("\n%d", sub[i]);

}

}

• 0

• 2

• 1

• 3
