Integer Constant

Constant integer expression. For example:

Real Constant

Constant expression that is a real number. For example:
double d = 34.75; // Real Constant, Representation is "34.75"

String Constant

Imaginary Unit Constant Imaginary Unit Constant

Imaginary Unit Constant

Macros that expand to constant expression of type const float _Complex, with the value of the imaginary unit. For example:

#include <complex.h>
void f1( void )
{
  I;            // Imaginary Unit Constant

}

Explicit Template Instance

Explicit template instances for types, functions and variables. For example:

    switch(i) {
    case 1: { break; }
    case 2: { break; }
    default: { break; }            // default
