Discussion Forum : Control Instructions - Point Out Correct Statements (Q.No. 5)
5.
Which of the following statements are correct about the below program?
#include<stdio.h>
int main()
{
int i = 0;
i++;
if(i <= 5)
{
printf("IndiaBIX\n");
exit(0);
main();
}
return 0;
}
Answer: Option
Explanation:
Step 1: int i = 0; here variable i is declared as an integer type and initialized to '0'(zero).
Step 2: i++; here variable i is increemented by 1(one). Hence, i = 1
Step 3: if(i <= 5) becomes if(1 <= 5) here we are checking '1' is less than or equal to '5'. Hence the if condition is satisfied.
Step 4: printf("IndiaBIX\n"); It prints "IndiaBIX"
Step 5: exit(); terminates the program execution.
Hence the output is "IndiaBIX".

In function 'main':
Line 11: warning: incompatible implicit declaration of built-in function 'exit'.
Line 15: error: expected declaration or statement at end of input.
If we compile the programme given in question then it gives above error statements.

Yes main can call itself
#include<stdio.h>
int i=0;
int main()
{
i++;
if(i <= 5)
{
printf("IndiaBIX\n");
main();
}
return 0;
}
o/p
IndiaBIX
IndiaBIX
IndiaBIX
IndiaBIX
IndiaBIX
#include<stdio.h>
int i=0;
int main()
{
i++;
if(i <= 5)
{
printf("IndiaBIX\n");
main();
}
return 0;
}
o/p
IndiaBIX
IndiaBIX
IndiaBIX
IndiaBIX
IndiaBIX

This is simple. It will print indiabix one time because there will be conditional statement presented. Instead of that if there while or for (looping statements) presented means it will printed 5 times.

@Syam.
Nothing will happen when we remove the inside main() function,
Because exit(0) will terminate the program, so the printf statement will execute one time.

B and C will be the correct options. As program terminates when exit(0) is called. So call to main() after exit() doesn't materialize.

Here, exit(0); requires <stdlib.h> included in file. Is'nt it?
as per this,it should give error.

According to me,
Answer should be C as stdlib.h isn't included and it hence cannot be resolved;

Will exit (0) and exit (1) both results in execution of exit statement?
