Get the ascii value for a char, Ord equivalent in C++

In delphi exist a function called Ord which Returns the ordinal value of an ordinal-type expression.

for example you can retrieve the Ascii value for a char in this way

Ord('A') return 65

Ord('a') return 97

in C++ which function i must use to get the ascii value for 开发者_StackOverflowa Char.?

A simple int a = c; where c is a char should work.

A char holds the ASCII value.

You can cast it to an integer if you prefer.

Typecast it using ascii = (int)character.

char c = 'a';
printf("%d", c);

this would do...

if you need to use the ascii value for numerical operations, use

char c = 'a';
int i = (int)c;

how about

#include <ctype.h>

int LOrdValue = __toascii('a');

you can do

char a ='A';
int b = a&0b11111111;

this should give 65
