Convert integer into Ascii character

1

How do I convert an integer into an Ascii character, Int=65 should give an “A”. I found intToAscii but what library do I need? I tried #include <stdio.h> but get “intToAscii was not declared in this scope”.

65 is already the ordinal number of the ‘A’ character.

>>> chr(65)
'A'
>>> ord('A')
65

If you have an int that is in the ASCII range (0-0x7F normally), then a pure case to char will do what you want.

int someNum = 65;  
char someChar = (char) someNum; //contains 'A'. Internally, still the exact same number.
                                // just a different interpretation of it.
