WebC++ has a predefined constant in its math library which we can use to access the value of pi wherever needed in our program. We use the following header file : #define _USE_MATH_DEFINES #include Here, _USE_MATH_DEFINES is a #define macro. Later in the program, we use M_PI to access the value of PI. WebThe #include occurs within cmath's header guards. This means that something higher up the list of #includes is including cmath without the #define specified. math.h is specifically designed so that you can include it again with that define now changed to add M_PI etc. This is NOT the case with cmath.
