/*取模运算Time Limit: 1000MSMemory Limit: 65536KTotal Submissions: 9753Accepted: 5952Description编写一个C函数mod(int n, int m),实现取模运算%Input输入包含多行数据 每行数据是两个整数a, b (1 <= a, b <= 32767) 数据以EOF结束Output于输入的每一行输出a%bSample Input5 3100 2Sample Output20*///法一： #include <stdio.h>int main(){//unsigned int a,b;//while(scanf("%u%u",&a,&b)==2){//printf("%u\n",a%b); //}int a,b;while(scanf("%d%d",&a,&b)==2){printf("%d\n",a%b);}return 0;}

//法二： #include <stdio.h>int main(){unsigned int a,b;while(scanf("%u%u",&a,&b)==2){while(a>=b){a=a-b;}printf("%d\n",a);}return 0;}
