Question

In C, while loop cannot be used to manipulate one-dimensional arrays. True or False

Answer 1

The above statement is False. Means we can manipulate the one-dimensional arrays using while loop. With the help of the loop we can check the condition and then we can manipulate the array.

For example:

code:

#include <stdio.h>
int main()
{
int a[10];//intializing array
int i=0, n, sum = 0, avg;
printf("Enter length of array: ");
scanf("%d", &n);
//checking the length of the array
while(i<n)
{
printf("Enter number %d: ",i+1);
scanf("%d", &a[i]);
sum += a[i];
i++;
}
avg = sum/n;
//printing the Average
printf("Average = %d", avg);

return 0;
}

Here the above example is used to find the average of the numbers in array . with the help of the while loop we just added the numbers to array and then increments the array length.
