分支结构问题
#include<stdio.h>int main(void){
int score;
scanf("%d",&score);
if( score < 60)
{
printf("The score is E!\n");
}
else if((score>=60|| score==60) && score<70)
{
printf("The score is D!\n");
}
else if((score>70|| score==70) && score<80)
{
printf("The score is C!\n");
}
else if((score>80 || score==80) && score<90)
{
printf("The score is B!\n");
}
else
{
printf("The score is A!\n");
}
return 0;
}
不懂,这里到底哪里错了哈- -·为什么一直编译不能通过
