Answer 1

#include <iostream>
#include <sstream>  

int main() {
    std::string s = "c++ programming";
    std::string ascii = "";
     
    int len = s.length();
    for (int i = 0; i < len; i++) {
        int asciicode = s[i] - 0;
        std::cout << asciicode << ' ';
        
        std::stringstream ss;  
        ss << asciicode;  
        std::string st;  
        ss >> st;  
        
        ascii = ascii + st;
    }
    
    std::cout << "\n" << ascii;
      
    return 0;
}
