C-language branching and cyclic recursive thinking

Conditional statements

Switching control Statements (switch statements)

Like an elevator, a break is a floor that is pressed, and will be executed without break.

The above program has detailed bug, boundary test input-5,105, because the integer division will get the wrong result.

Workaround:

Cycle

The difference between a type loop and a to-type loop is whether the condition is true at first execution

About the comma operator

Recursive

Forward recursive and reverse recursion

#include <stdio.h>intMain () {intX,n; N=1; X=1;  while(n<=9)//need to be pushed 9 times{x=2* (x+1); N++; } printf ("x=%d", x);    GetChar ();    GetChar (); return 0;}
