c math.h sqrt

Explanation of C math.h sqrt Function

The sqrt function in C is used to calculate the square root of a given number. It is part of the math.h library in C.

Here's a simple example of how to use the sqrt function in C:

#include <stdio.h>
#include <math.h>

int main() {
    double number = 25.0;
    double squareRoot = sqrt(number);
    printf("The square root of %f is %f\n", number, squareRoot);
    return 0;
}

In this example, we include the math.h header file to access the sqrt function. We then declare a variable number and assign it a value of 25.0. We calculate the square root of number using the sqrt function and store the result in the variable squareRoot. Finally, we print the result using printf.

Key Points: - The sqrt function is used to calculate the square root of a number in C. - It is part of the math.h library in C.
