给出以百分之成绩,要求输出成绩登记‘A’‘B’‘C’‘D’‘E’。90分以上为A,80-89为B,70-79位C,60-69为D,60分以下为E
<>题目分析
这是一个典型的分支结构的题目,可以通过多分支if语句进行判断,可以先判断60分以下,再依次向上判定,也可以先判定90分以上,再依次向下判定
<>程序
直接将两种判定方法写为函数,程序如下:
#include "stdio.h" int fun1(int i) { if(i>=90) printf("A"); else if(i>=80)
printf("B"); else if(i>=70) printf("C"); else if(i>=60) printf("D"); else printf
("E"); } int fun2(int i) { if(i<60) printf("E"); else if(i<70) printf("D"); else
if(i<80) printf("C"); else if(i<90) printf("B"); else printf("A"); } int main()
{ int score; scanf("%d",&score); printf("\n 方式1:"); fun1(score); printf("\n
方式2:"); fun2(score); }
