C语言入门样例，包含输入输出、函数调用。由于整个程序的注释是我写的，风格也是我的编程风格，所以归在原创类。

代码开始：

/*

/* TC 2.0 can ignore */
#include <stdio.h>

/* declaration max function, TC 2.0 can ignore */
int max(int x, int y);        

/* main function */
int main()                
{
        int a,b,c;                                /* define variable */

        scanf("%d%d",&a,&b);        /* input,pay attention */

        c=max(a,b);                                /* call max function */

        printf("max=%d\n",c);        /* output */
        
        system("pause");                /* pause the programme */

        return 0;                                /* return 0, terminate the programme */
}


/* define max function */
int max(int x, int y)

        int z;

        if(x>y)
        {
                z=x;
        }
        else
        {
                z=y;
        }

        return (z);
