Replacing space with a hyphen in C++

In this C++ program, the space in the string will be replaced with the hyphen. Firstly, the length of the string is determined by the length() function of the cstring class, then hyphen is filled into the space of the sentence by traversing the string as follows.

Example

 Live Demo

#include <cstring>
#include <iostream>
using namespace std;
int main(){
   // raw string declaration
   string str = "Coding in C++ programming";
   cout<<"Normal String::"<<str<<endl;
   for (int i = 0; i < str.length(); ++i) {
      // replacing character to '-' with a 'space'.
      if (str[i] == ' ') {
         str[i] = '-';
      }
   }
   // output string with '-'.
   cout <<"Output string::"<< str << endl;
   return 0;
}

Output

The output of the program is yield with hyphen tweak as following when the user enters the string as following;

Normal String::Coding in C++ programming
Output string::Coding-in-C++-programming
