Question

What should be put in the blank position below in order to make the loop execute exactly 5 times? (C program)

int i ;

for ( i = 10 ; ______ ; i-- ){
  printf ( "%d\n", i ) ;
}

Answer 1

Based on the condition in the question loop needs to execute 5 times.

So, We need to fill the blank position with i>5

Step1:

Initially the value of i is 10 then we check the condition i>5 if it is true then enter into the loop and print the i value.

Step2:

Next it decrement the i value i.e..(i--) and check the condition again I>5 if it is true then enter into the loop and print the i value.

Step3:

The loop will run till the condition is true i.e..(i>5). Once the i value less than or equal to 5 loop will be exit.

Code:
#include <stdio.h>

int main()
{
int i ;

for ( i = 10 ; i>5; i-- )
{
printf ( "%d\n", i ) ;
}
}

O/p:

10

9

8

7

6

As per the condition loop ran only 5 times.
