writing to a text file in a specific location

[ecrovoyan]

I am trying to write a c++ program that reads through a text file and when i comes across a specific line it adds to that file. i have this code, but it doesnt write "meow" until the end of the text file.. does anyone know how i can get it to write meow on the line after "putwordhere"?? ??????????

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

int main(){
string line;
string searchage;
searchage = "putwordher e";
ifstream Myfile ("random.txt ");
while(line != searchage){
getline(Myfile, line);
if (line == searchage);{
Myfile.close();
ofstream a_file ("random.txt ", ios::app);
a_file << "\n";
a_file << "meow";
a_file.close();
cin.get();
}
}
cin.get();
}

I don't think it's a good idea to open the same file for both reading and writing - it could severely mess things up.

Why not read the entire file into a string, look for the portion you want to write after, insert the "meow" (or whatever string needed), and then output the new string to the file?
