#includevoid main(){ int points; char grade; printf("Please enter your points:"); scanf("%d",&points); switch(points/10) {/*case跟数字之间要有空格*/ case 0: case 1: case 2: case 3: case 4: case 5:printf("E");break; case 6:printf("D");break; case 7:printf("C");break; case 8:printf("B");break;

你的switch没有default.所以看不到是否有错,可能是你输出的结果/10的大于10了还有你的grade并没有赋值
