#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?
