C ++ FAQ: if, while, do-while, for is not required, All integers greater than 0 and less than K are printed. Void printless (int K) is a function prototype );

During the written test, I thought about how to implement the function by defining a class and using its automatic execution feature of constructor. However, if I want to do that, I certainly did not meet the requirements of the question.

After returning to school, I thought about the solution to this question from time to time and finally came up with a solution.

Solution 1: recursion (just come up)

# Include <iostream> using namespace STD; void printless (int K) {Switch (-- k) {Case 0: return; default: cout <k <Endl; printless (k) ;}int main () {printless (10 );}

Solution 2: Category

Class test {public: static int K; test () {cout <k ++ <Endl ;}}; int test: K = 1; void _ printless (int K) {test T [k-1];}
