How to concat two chars into a string?

#include <iostream>

int main()
{
	std::string myString;
								//output
	myString = '2';
	std::cout << "myString: " << myString << std::endl;	//2

	myString = '2' + ' ';
	std::cout << "myString: " << myString << std::endl;	 //R, why??
}

output:

myString: 2
myString: R

Why is "R" printed?

Thank you.

Because a char is an ASCII code:

'2' = 50
' ' = 32

R = 50 + 32

Thanks megatron. That makes sense.

This works as expected:

#include <iostream>

int main()
{
	std::string myString;
								//output
	myString = '2';
	myString += ' ';
	myString += '3';
	std::cout << "myString: " << myString << std::endl;	//2 3
}

output:

myString: 2 3

Excellent work mate, glad you could figure it out. Just remember that variables are variables, and if they can be added, they will.
