sqrt cpp

The sqrt() function in C++ is used to calculate the square root of a given number. It is defined in the <cmath> header file. When using this function, the number inside the parentheses is the value for which we want to find the square root. The function returns the square root of the given number as a double type. Here's an example of how to use the sqrt() function in C++:

#include <iostream>
#include <cmath>

int main() {
    double number = 16.0;
    double result = sqrt(number);
    std::cout << "The square root of " << number << " is " << result << std::endl;
    return 0;
}
