A C program that can find square

This is a program that takes a number as input from the user and then prints its square.

C program:-

#include<stdio.h>

#include<conio.h>

void main(void)

{

//*program that can calculate square of a number

int nmbr,sqr;

clrscr();

printf("Enter the number which you want the square=");

scanf("%d",&nmbr);

sqr=nmbr*nmbr;

printf("\n The square of %d is %d\n",nmbr,sqr);

getch();

}

Output:-

                    Enter the number which you want the square= 3

                    The square of 3 is 9

Second Method:-

#include<stdio.h>
#include<conio.h>
#include<math.h>
void main(void)
{
//*program that can calculate square of a number
int nmbr,sqr;
clrscr();
printf("Enter the number which you want the square\n");
scanf("%d",&nmbr);
sqr=pow(nmbr,2);
printf("the square of %d is %d\n",nmbr,sqr);
getch();
}

NOTE:-

           In this program we use a built in math function "pow" and its syntax is pow(number,exponent); and for using this function we must have to use #include<math.h>
