Question

IN C++
Create a method called xChar that will replace a specified char in a String with the 'X' character. Your function must use a pointer to search and replace the char. You are not allowed to use array notation to solve this problem.
Your function should take as arguments in the CString to search through and a char variable that holds the char to be searched for and replaced. The function should also return the number of replacements made.

Example:

Enter some text

Hello Word

Enter a character to x

o

here is your output

Hellx Wxrd

/*
 *  C++ Program to replace a character in a string
 */

#include <iostream>
using namespace std;

#define MAX 30

int xChar(char *str, char x)
{
  int count = 0;

  for (int i = 0; (*(str + i)) != '\0'; i++)
  {
    if (*(str + i) == x)
    {
      *(str + i) = 'x';
      count++;
    }
  }
  
  return count;
}

int main()
{
  char text[MAX], X;

  cout  << "Enter some text " << endl;
  cin.getline(text, MAX);

  cout << "Enter a character to x " << endl;
  cin >> X;

  xChar(text, X);

  cout << "here is your output" << endl;
  cout << text;

  return 0;
}
