How to convert a string to integer in C?

Question

I am trying to find out if there is an alternative way of converting string to integer in C.

I regularly pattern the following in my code.

char s[] =

In C++, you can use a such function:

template 
T to(const std::string & s)
{
    std::istringstream stm(s);
    T result;
    stm >> result;

    if(stm.tellg() != s.size())
        throw error;

    return result;
}

This can help you to convert any string to any type such as float, int, double...
