编写成绩转换程序,输入成绩等级ABCDE,分别转换输出为优秀,良好,中等,及格和不及格，要c语言

void main() { char str[5][10]={ "优秀","良好"哪猜,"中等","及格","不及搏顷格" },str1[20],c

printf("请输入成绩等级: ")scanf("%s",str1)c=str1[0]

if ( c>='A' &&c<='E' ) printf("成绩%c: %s\n",c,str[c-'A'])

else printf("无效的成绩等基缓陆级。\n")

}

#include <银烂羡stdio.h>void main(){int scorescanf("%d",&score)//输入成绩if(score>=90) printf("历滚优秀")else if(score>=70&&score<90) printf("良好")else if(score>锋拍=60&&score<70) printf("及格")else if(score<60) printf("不及格!")}

#include<stdio.h>

int main()

{

int nscore = 0

scanf("%d",&nscore)

if ( nscore >高派 90 )

{

printf("成绩优！\n")

}

else if ( nscore >80 )

{

printf("成绩良！\n")

}

else if ( nscore >60 )

{

printf("成绩毁烂及格！\n")

}

else

{

printf("成纤念漏绩不及格！\n")

}

return 0

}
