replacing a part of a string

Hello folks.. Can someone suggest me a way of replacing a part of a string with something else? What I mean is:

Code:

---

int main()
{
string someString("My name is michael");
replace(someString,"michael","alex");
return 0;
}

---

Here I want to know if there is a generic way of doing this. Any help will appreciated. Thanks

no, I think that you would have to create an array of chars and replace them manually according to the index number of each char...

Have a look around for some examples of substr, there are quite a few on the web, it needs to know the start position of the part of the string you want to change, and the length of the string. "The C++ Programming language" gives the example...

Code:

---

string name = "Niels Stroustrup";

void m3()
{
string s = name.substr(6,10);
name.replace (0,5,"Nicholas");
}

---

This replaces Niels with Nicholas
