Convert the ASCII value sentence to its equivalent string in C++

In this tutorial, we will be discussing a program to convert the ASCII value sentence to its equivalent string.

For this we will be provided with a string containing the ASCII codes. Our task is to convert the given string into the equivalent characters and print it back.

Example

 Live Demo

#include <bits/stdc++.h>
using namespace std;
//converting the ASCII sequence into
//character string
void convert_ASCII(string str, int len){
   int num = 0;
   for (int i = 0; i < len; i++) {
      //appending the current digit
      num = num * 10 + (str[i] - '0');
      //checking if number is within range
      if (num >= 32 && num <= 122) {
         char ch = (char)num;
         cout << ch;
         num = 0;
      }
   }
}
int main(){
   string str = "104101108108111443211911111410810033";
   int len = str.length();
   convert_ASCII(str, len);
   return 0;
}

Output

hello, world!
