C program to find square of an integer?

Answer 1

#include
#include
void main()
{
long int n;
printf("Please enter the number");
scanf("%ld" ,&n);
n=n*n;
printf("Square of entered number = %ld ");
}

but if you want to show the entered number e.g.Square of the entered number 8=64

then below is the code.

#include
#include
void main()
{
long int m,n;
printf("Please enter the number");
scanf("%ld" ,&n);
m=n;
n=n*n;
printf("Square of entered number %ld = %ld ",m,n);
}
