strncpy(t5+strlen(t5),t6,t4-t6);
strcat(t5,t2);

The basic has a function called "Replace" which takes 3 strings and does as i described. I looked at the string::replace but none of its forms can take the 3 stings and do the job. If i use a position and size then surely if the replacer is longer than the replace-ee then thats going to overwrite more than i want it too :/ Plus im not sure how to even get the position or length i need either

#include <iostream>
#include <stdio.h>
#include <fstream>
#include <string>

using namespace std;

string Replace(string a,string b,string c)
{
int pos = a.find(b);
a.replace(pos, c.length(), c);

return a;
}

int main()

{
std::cout << Replace(" Hello World","Hello","goodbye");
}

This is my attempt but i am getting
goodbyeorld

As its simply overwriting rather than resizing a.

edit:
Ah ok fixed it, i needed to supply the length of b. Now i just need to make it parse the whole string

Is this the best way of doing this? by (dman (20) )

This looks like a sophisticated spam bot.

And of course the n00b has a link in his sig LOL.
