Take Full Control on Files

[rock3t]

Hi there,

i have writing program which takes file name(full path) and do some modification on these file.

Assuming we have a file that ready to work.
file.txt:
name id age
name id age
name id age
name id age

if i wanna change the id to specific string what function should i use?

#include <iostream>
#include <fstream>
#include <string>
using namespace std;

int main(){
    ifstream file("file.txt");
    string buffer;

    
    getline(file, buffer);
    /*
    
        Here i will change buffer's content to do( modification )
    */
    cout<<buffer<<endl; // print out our new data
    file.close();
    return 0;
}

Look at the stringstream functions to help process the individual elements of your string.
