In C, suppose we have a function like this:
Int function (int A, int B)
You can use this function by using result = function. However, when a high-level language is compiled into a machine code that can be recognized by a computer, a problem arises: In the CPU, the computer cannot know how many or what parameters are required for a function call, and there is no hardware to save these parameters. That is to say, the computer does not know how to pass

Three key function call conventions and key function call conventions
After the advanced language is translated into a machine code, the computer cannot know the number, type, and hardware of the parameters called by the function.
In addition, in C ++, the function naming method is different from that in general C language because of overload. This method is called name adaptation.
