#include <iostream>
#include <cmath>

using namespace std;

double func(double num, double pow)
{
	return(pow(num, pow));
}

int main()
{
	return(0);
}


 error: `pow' cannot be used as a function


If I add std:: before pow, it works:


double func(double num, double pow)
{
	return(std::pow(num, pow));
}

You declared a local variable (parameter) which shadows pow so this is invalid.
try the following:
double func(double num, double pow1)
{
        return(pow(num, pow1));
}

Could not -Wshadow (or maybe something similar) warn about these things?
