Question

Why does Visual Studio add a slash at the start of an int, when it’s converted to char?

When I convert int 0 to char, it changes to \0. Why? I need char 0.

Answer 1

\0 is just how Visual Studio shows the character null in debug windows.

The \ is an escape sequence, so \0 tells you this is the null character.

If you want the character 0, you need to use the correct ASCII value for that character – 48.

char n = (char)0; // The _null_ character, displayed \0
char z = (char)48; // The character 0
char z2 = '0'; // The character 0, using a character literal
