#include #define M 100 void main() { static int count=0; int money = M; int i5 , i2 , i1 ; printf("5f , 2f , 1f /n"); printf("--------------------/n"); for(i5 = 0 ;i5 <= money/5 ;i5++) for(i2 = 0 ;i2 <= (money - i5 * 5)/2 ;i2++) { if((i1 = (M-i5*5-i2*2)) >= 0) { printf("%3d , %3d , %3d /n",i5,i2,i1); count++; } } printf("--------------------/n"); printf("total %d Types!/n",count); }
