I'm having a hard time converting the ASCII counterpart of each char in string, my objective is to convert the average of each word for example: if the user input "love" the code will return 54, the thing is this code is inside a loop and if the user input for example; Word no.1: "love" Word no.2: "love" the code should return; 54 54 but my code returns 108 i guess the problem is in this part sum = static_cast<int>(compute - 64); but I don't know the right approach for my problem

 for(int x = 1; x <= numofinput; x  ){
            cout << "Word no. " << x << ": ";
            getline(cin,words);
            
            for(auto compute : words){
                if(isalpha(compute)){
                    compute = toupper(compute);
                    sum  = static_cast<int>(compute - 64); 
                }
            }
        }

You need to set sum = 0; for each word you do calculations on. There are also a number of other small issues that I've commented on in this example:

#include <cctype>
#include <iostream>
#include <string>

int main() {
    int numofinput = 2;

    for(int x = 1; x <= numofinput; x  ) {
        std::cout << "Word no. " << x << ": ";

        if(std::string word; std::cin >> word) { // read one word
            int sum = 0;                         // only count the sum for this word

            // auto& if you'd like to show it in uppercase later:
            for(auto& compute : word) {

                // use unsigned char's with the cctype functions:
                auto ucompute = static_cast<unsigned char>(compute);

                if(std::isalpha(ucompute)) {
                    compute = static_cast<char>(std::toupper(ucompute));
                    sum  = compute - ('A' - 1);  // 'A' - 1 instead of 64
                }
            }

            std::cout << "stats for " << word << '\n'
                      << "sum: " << sum << '\n'
                      << "avg: " << static_cast<unsigned>(sum) / word.size() << '\n';
        }
    }
}
