Answer 1

#include <algorithm>
#include <iostream>

std::string shiftUpNCharacters(std::string str, int N) {
    std::transform(str.begin(), str.end(), str.begin(),
                   [&](unsigned char ch) -> unsigned char { return ch + N; });
                   
    return str;
}

int main()
{
    std::string str("3a Fkq");
    
    str = shiftUpNCharacters(str, 3);

    std::cout << str << std::endl;
