Replacing words with asterisks in C++

This aim of this program to replace a particular word with asterisks in the string by using the c++ programming code. The essential function of vector and string class essay a key role to achieve the prospective results. The algorithm is as follows;


   Step-1: Input string
   Step-2 Split the string into words and store in array list
   Step-3: Iterate the loop till the length and put the asterisk into a variable
   Step-4: Traverse the array foreah loop and compare the string with the replaced word
   Step-5: Print

Now, the following code is carved out based on the algorithm. Here, the strtok() method of string split the string and returns the array list type of vector class.


#include <cstring>
#include <iostream>
#include <vector>
#include <string.h>
//method for spliting string
std::vector<std::string> split(std::string str,std::string sep){
   char* cstr=const_cast<char*>(str.c_str());
   char* current;
   std::vector<std::string> arr;
   return arr;
int main(){
   std::vector<std::string> word_list;
   std::cout<<"string before replace::"<<"Hello ajay yadav ! you ajay you are star"<<std::endl;
   std::cout<<"word to be replaced::"<<"ajay"<<std::endl;
   word_list=split("Hello ajay yadav ! you ajay you are star"," ");
   std::string result = "";
   // Creating the censor which is an asterisks
   // "*" text of the length of censor word
   std::string stars = "";
   std::string word = "ajay";
   for (int i = 0; i < word.length(); i++)
      stars += '*';
      // Iterating through our list
      // of extracted words
      int index = 0;
      for (std::string i : word_list){
         if ( == 0)
         // changing the censored word to
         // created asterisks censor
         word_list[index] = stars;
      // join the words
      for (std::string i : word_list){
         result += i + ' ';
      return 0;

As seen in the above code, all string operation code is bundled into the retrieveChar() method, later on, which call is passed to program main() execution.


String before replace::Hello ajay yadav ! you ajay you are star
Word to be replaced::ajay
Output::Hello **** yadav ! you **** you are star
