Use C instead of C
1. Use const instead of #define to create a constant 2. Replace #define with enum to create a constant collection 3. Inline function instead #define macro 4. Use new and delete instead of Malloc and Free5. Use the input and output stream ( iostreams instead of stdio6. Select C language instead of C pre-processed, but you need to use preprocessors 7 when you debug code. Detect the value of the floating point pointer. The floating point pointer does not have a precise binary representation, so don't expect them to have precise values. Therefore, it is also necessary to use a method of comparing the values of the two floating point pointers to determine whether the two are equal. EG: #include
