Thread: Get the number of letters stored in a text file

You don't need to store the text. You can read the file char by char and check if if is a letter.

Code:

#include <iostream>
#include <fstream>


int main()
{
    if(std::ifstream input{__FILE__})
    {
        char ch;
        int letterCount = 0;
        
        while(input.get(ch))
        {
            // if ch is letter increment letterCount;
        }
        // output letterCount
    }
    else
        std::cerr << "Error opening file\n";        
}

BTW:
C++ is not C where you need to allocate arrays or strings. std::string and std::vector will do this for you.
