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.
