Question

4. What will be the output of the
program ? int main() { int a[3] =
{10,12,14}; a[1]=20; int i=0; while(i<3) {
printf("%d", a[i]); i++; } }​

Answer 1

Answer:

output:⬇️

10 20 14

Explanation:

a[i] is (i+1) element. So a[1] changes the second element.

Answer 2

Concept:

While loop is also known as a loop that has been pre-tested. A while loop, in general, allows a section of code to be run many times depending on a boolean state. It can be thought of as a repeated if statement.

Given:

#include <stdio.h>

int main()

{ int a[3] = {10,12,14};

a[1]=20;

int i=0;

while(i<3)

{

   printf("%d ", a[i]); i++; }

}

Find:

Find the output.

Solution:

Here a is a one-dimensional array having three values {10, 12, 14}

a[1] = 20 will change the value of the item at index 1 to 20.

∴ The updated array would be (10, 20, 14)

while(i<3) will execute the following code 3 times and print the value of each item of the array.

Output: 10, 20, 14

∴ The output will be 10, 20, 14.
