The C language provides the four basic arithmetic type specifiers char, int, float and double, and the modifiers signed, unsigned, short, and long. The following table lists the permissible combinations in specifying a large set of storage size-specific declarations. The actual size of the integer types varies by implementation. The standard requires only size relations between the data types and minimum sizes for each data type: WebAug 16, 2015 · Petar Brkovic said that never to use char for a number - which is correct to an extent. A char is an integer, just one which you will never see as that integer is machine code (ie 0's or 1's). Char's are individual characters, for example you can store a line of text in an array of type char with an allocated size that matches the size of your ...
