replace function. which header file ?

**joeyzt** · 01-05-2006

Seems to be in <iostream> but i have that referenced and am still getting a

384 `Replace' undeclared (first use this function)

<algorithm>, if you're talking about 'replace' (not 'Replace').

**major_small** · 01-05-2006

there's also a replace function in <string>

I very highly recommend this resource: http://www.cppreference.com/index.html

Its Replace, does that mean it a custom function ?. Also, this probably a bit newb but my algorithm 'header' is just a file no extension ?

Argg...

I need a function that will replace a string with function in the form.

Replace(strString,".",",");

any ideas ?

I'm not sure, what is the value in strString, and what do you expect the output to be?

**joeyzt** · 01-05-2006

For example char strString = "hello,world"

Replace(strString,",",".")

would yield,

hello.world

So

replace(charater(s),find character(s),replace with)

.

that'd be the one in <algorithm>:

Code:

#include <iostream>
#include <algorithm>
#include <string>

int main()
{
	std::string s1="Hello,World";
	std::cout<<"Original: "<<s1;
	replace(s1.begin(),s1.end(),',',' ');
	std::cout<<"\nNew: "<<s1<<std::endl;
	return 0;
}

output:

Code:

Original: Hello,World
New: Hello World
