C Program to Calculate Square of a Number

How to write a C Program to Calculate Square of a Number using Functions with an example?.

C Program to Calculate Square of a Number

This program allows the user to enter an integer value and then finds the square of that number using the Arithmetic Operator.

/* C Program to Calculate Square of a Number */
 
#include<stdio.h>
 
int main()
{
  int number, Square;
 
  printf(" \n Please Enter any integer Value : ");
  scanf("%d", &number);
  
  Square = number * number;
  
  printf("\n Square of a given number %d is  =  %d", number, Square);
 
  return 0;
}

Program to Calculate Square of a Number using Functions

This C program to calculate square in allows the user to enter an integer value. And then, it finds the square of that number using Functions.

From the below C Programming code snippet, you can see we are using the Calculate_Square function. When the compiler reaches to Calculate_Square(number) line in main() program, the compiler will immediately jump to int Calculate_Square (int Number) function.

Calculate_Square (int Number) function will calculate the square and return the value.

/* C Program to Calculate Square of a Number using Function */
 
#include<stdio.h>

int Calculte_Square(int Number);
 
int main()
{
  int number, Square;
 
  printf(" \n Please Enter any integer Value : ");
  scanf("%d", &number);
  
  Square = Calculte_Square(number);
  
  printf("\n Square of a given number %d  =  %d", number, Square); 
 
  return 0;
}

int Calculte_Square(int Number)
{
	return Number * Number;
}

 Please Enter any integer Value : 9

 Square of a given number 9  =  81
