string occurences

outofmymind

Hi,

im doing this question:
Replace all the occurrences of a string in a file and report number of replacements.

I did the first part of the question, but im having problems with the second part, i which i have to report the number of replacements.

this is the code that i did so far:

Expand|Select|Wrap|Line Numbers

 #include <iostream>

#include <conio.h>

#include <fstream>
 
using namespace std;
 
int main()

{

    string whole_file, str;

    ifstream in ("file.txt");

    while (!in.eof())

    {

          std::getline(in,str,'\n');

          whole_file = whole_file + str + "\n";
 
    }
 
  int pos = 0;
 
  while (pos!=-1 && pos<whole_file.length())

  {

    pos = whole_file.find ("money", 0);

    if (pos!=-1)

    {

      cout<<whole_file.replace(pos, 5, "university", 10);

}

}

cout<<whole_file;
 
getch();

return 0;
 
}

Thanks..... all help on how i can solve the second part of the question will be very much appreaciated.

all you need is a counter which you increment when you replace a string, e.g.

Expand|Select|Wrap|Line Numbers

 
  int pos = 0, counter=0;
 
  while (pos!=-1 && pos<whole_file.length())

  {

    pos = whole_file.find ("money", 0);

    if (pos!=-1)

    {

      cout<<whole_file.replace(pos, 5, "university", 10);

      counter++;

}

}
