C++ | Square of numbers from array

Introduction

The program to calculate the square of numbers from array. The program below will guide you to do the program. The program cannot the extended. Go enjoy the program. Lets begin…….

Program to calculate the square of numbers from array

#include<iostream.h>
#include<conio.h>
void main()
{
//clear the screen.
clrscr();
//declare variable type int
int a[10],i,sq;
//Input the two numbers save them in arrays.
//Here for loop is used to input multiple numbers in array.
for(i=0;i<5;i++)
{
cout<<“Enter the no.”<<endl;
cin>>a[i];
}
//cout
cout<<“Squares are :- “;
//show the output square of arrays
for(i=0;i<5;i++)
{
sq=a[i]*a[i];
cout<<sq<<” “;
}
//get character
getch();
}

Output

Enter the no.
