一、问题
对输入的成绩进行等级划分
二、分析
使用if-else嵌套语句时必须注意else与if的配对正确
三、源码
1: #include <stdio.h>
2:
3: int main()
4: {
5: int nScore;
6: printf("please input the score\n");
7: scanf("%d", &nScore);
8: if (nScore < 80)
9: {
10: if (nScore < 70)
11: {
12: if (nScore < 60)
13: {
14: printf("E\n");
15: }
16: else
17: {
18: printf("D\n");
19: }
20: }
21: else
22: {
23: printf("C\n");
24: }
25: }
26: else
27: {
28: if (nScore < 90)
29: {
30: printf("B\n");
31: }
32: else
33: {
34: printf("A\n");
35: }
36: }
37: getchar();
38: return 0;
39: }
