Answer

• 0-d. error

Answer 2

programs.

Question 1

c

#include<stdio.h>

char *getString()

{

char str[] = "Will I be printed?";

return str;

}

int main()

{

printf("%s", getString());

getchar();

}

Output: Some garbage value

The above program doesn’t work because array variables are stored in Stack Section. So, when getString returns values at str are deleted and str becomes dangling pointer.

Question 2

C

#include<stdio.h>

int main()

{

static int i=5;

if(--i){

main();

printf("%d ",i);

}

}

Output

0 0 0 0

Explanation: Since i is a static variable and is stored in Data Section, all calls to main share same i.

Question 3

c

#include<stdio.h>

int main()

{

static int var = 5;

printf("%d ",var--);

if(var)

main();

}
