recursive invocation of functions

Serial 1

First came to infinite interconnection, although there are a lot of things do not understand, but with the teacher patient introduction and careful care, he quickly adapted to the environment here, really thank the unlimited connected teachers.

This week is our first week of training, with a lot of classmates in the Tang Dynasty accompany, boring training life is not so boring, see the class more than the students from Anhui, Hunan, suddenly feel that the original North drift of their own is not so hard, than our efforts, than we have the courage, more than our hard prospective graduates.

the first week of training self-feeling is good, because at school time C Language Foundation is also good, very relaxed can keep up with the teacher's progress, hope later can also study very good.

The most impressive thing about this week is the use of recursive functions, with two recursive invocation examples to help you understand:

#include <stdio.h>

void recursive (int a)

{

// If a condition that does not jump out of the loop calls causes a dead loop call

if (a = = 0)

{

// jump out of loop call

return;

}

printf ("%d\n", a);

A--;

// recursive invocation

Recursive (a);

}

// factorial recursive invocation

int factorial (int a)

{

if (a = = 1)

{

return1;

}

return A * factorial (A- 1);

}

int Main (int argc, charconst *argv[])

{ //1. Decrement Output 3 2 1   

    // Recursive invocation

recursive (ten);

//2 to find factorial 5*4*3*2*1

int res = factorial (5);

printf ("5*4*3*2*1=%d\n", res);

return 0 ;

}
