WebBefore any data type can be used to create a variable, the size of the type must be known to the compiler: structNODE { intvalue; structNODE next; /* illegal */}; Since the compiler hasn't fully "seen" the NODE struct, it can't be used anywhere, even inside itself. this works: structNODE { intvalue; structNODE *next; /* OK */}; 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:
