I have an integer 1 and i want to display it as a character ‘1’ in C++. So far I have only managed to convert it from say integer 65 to character ‘A’.
How do you stop this ?

This works because it’s guaranteed1 that the sequence of characters
'0'…'9'is contiguous, so if you add your number to ‘0’ you get the corresponding character. Obviously this works only for single digits (iftheDigitis e.g. 20 you’ll get an unrelated character), if you need to convert to a string a whole number you’ll needsnprintf(in C) or string streams (in C++).By the way, I suppose that they didn’t mandate contiguity also in the alphabetical characters just because of EBCDIC.
