What is wrong with my itoa conversion?

Background

Im trying to determine character codes for some national diactric letters.

Problem

Is something is wrong with my code?

char a = "a"; // "a" ascii code is 97

char buffer[8];

itoa(buffer,(int)a, 10);

print(buffer); // but it prints "252" instead of "97"
Solution

  • The character code for 'a' is indeed 97, but "a" is of type char *. Single quotes ' encode characters, double quotes " encode string literals.

    Try

    char a = 'a';
