Title: There are 1, 2, 3, 4 numbers, can make up how many different and no repetition of the number of three digits? How much are they?Program Analysis: This is a mathematical permutation, because the number given is not 0, so there are 4*3*2=24

The cross-platform features of C/s + + are more primitive than Java (Java is a compile-time operation, and C/s + + needs to be recompiled with the source code), and implementing a cross-platform program for C/s + + is generally a few practices: 1.

#include //defines a global variable, which is also a static variable. stored in a static area, not enough auto modifier int d;//function declaration void autofaction (int a, int b); void staticfaction (); void registerfation (); int main () {// Use

A nested class of C + + means a class defined in a class that is similar to a member of a perimeter class and is decorated with the appropriate access modifier.1 a nested class can directly orient a static member variable in a perimeter class.2
