Creating String from Char & Int

[Jacky Billards]

Hello, I have been working on a program that outputs various chars and ints, but I need a way to put them together into a string
For example if I had:

char a = 'a';
char b = 'B';
int c = 1;

I would like a way to make that into a string that says:
aB1
Any help would be much appreciated.
