Program to find square of all elements of an array

Program:

#include<stdio.h>

void main()

{

int i;

float a[5],b[5];

printf("Enter float array of whose you want to find square: \n");

for(i=0;i<5;i++)

{

scanf("%f",&a[i]);

b[i]=a[i]*a[i];

}

printf("\nSquare of entered array is: \n");

for(i=0;i<5;i++)

{

printf("%f\n",b[i]);

}

}

Output:

Explanation:

As seen in program we have created another array to store square of first array we can also store square in same array by replacing b[i]=a[i]*a[i] by a[i]=a[i]*a[i].

This will lead to less memory usage.

Since no second array is created so our memory is saved.
