Thread: find a char in a string

Hello,

I am trying to find and replace a character in a string.

Code:

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

int main()
{
	string s("This is a piece of text.  All of the \"a's\" will be replaced by \"XXX's\".");
	const char target = 'a';
	string replace_with("XXX");
	
	size_t pos = 0;
	while(pos != string::npos)
	{
		pos = s.find(target, pos, 1);
		if(pos != string::npos)
		{
			s.replace(pos, 1, replace_with);
			pos++;
		}
	}
	
	cout << s << endl;
	
	return 0;
}

I am getting an error on the line that defines target.

error: invalid conversion from ‘char’ to ‘const char*’

If I put "a", in find(), in place of target it works.

The version of find that takes a single char as the first argument does not contain a third argument. (In fact, most of the versions of find don't take a third argument.)
