Implementation of square() Function

To implement a square() function in C that calculates the square of a number, you can create a simple function that takes an input number and returns its square. Here's an example of how to implement the square() function:

Example:


#include <stdio.h>

// Function to calculate the square of a number
double square(double num) {
    return num * num;
}

int main() {
    double number = 5.0;
    double result = square(number);

    printf("The square of %.2f is %.2f\n", number, result);

    return 0;
}

In this example:

  • The square() function takes a double-precision floating-point number (double num) as its parameter and returns the square of that number by multiplying it by itself.
  • In the main() function, a number (5.0 in this case) is passed to the square() function, and the result is stored in the result variable.
  • Finally, the program prints the result, showing the square of the input number.

Output:


The square of 5.00 is 25.00

You can use this square() function to calculate the square of any number by passing it as an argument to the function.
