How to shift each letter in a string N places up in the alphabet with C++

Answer 1

#include <iostream>

std::string shiftEachLetterNPlacesUp(std::string str, int N) {
    std::string result;
    
    for (char ch : str) {
        int asciiCode = static_cast<int>(ch) + N;
        if ((asciiCode >= 97 && asciiCode <= 122) || (asciiCode >= 65 && asciiCode <= 90)) {
            result += static_cast<char>(asciiCode);
        } else {
            result += ch;
        }
    }
    
    return result;
}

int main() {
    std::cout << shiftEachLetterNPlacesUp("8a Fkq", 3) << std::endl;
}
