How to convert a char to int in C during initialization

I want to compare two char types in C++. I tried cout<<"x"=="x"; to see the result and it wont work(which I believe is normal), so I tried converting it by trying int letter = "x" to try to compare it by it ASCII number. This gets me the error;

error:invalid conversion from 'const char*' to 'char'

Shouldn't this work? If not, what should I be doing?

  • "x" is an array of chars - string - (2 bytes - one for char x, one for char \0 nul)
  • 'x' is char - variable represented by 1 byte in memory.

Assigning "x" to an int variable is an obvious mistake.

Try 'x' instead of "x": int letter = 'x'; should work fine.

You are using double quotes around your characters.

Double quotes are of type const char*, not type char

Try 

int letter = 'x';

"x" gives you a nul-terminated array of characters {'x','\0'}.

Use 'x' if you want a single char
