我昨天做的,试试吧!#include"math.h"main(){int x,y,sum,i,score=0,answer;for(i=1;i<=10;i++){x=rand();y=rand();printf("di%2dti %2d+%2d=?\n",i,x,y);scanf("%d",&answer);if(answer==x+y){score+=10;printf("right!\n");}elseprintf("wrong!\n");}printf("\nde fen:%d\t",score);score/=10;switch(score){case 0:case 1:case 2:case 3:case 4:case 5:printf("bu ji ge\n");break;case 6:case 7:printf("ji ge\n");break;case 8:printf("liang hao\n");break;case 9:printf("you xiu\n");}} |
