#include<stdio.h>
main()
{int x;

scanf("%d",&x);
if(60<=x<=69)
printf("\njige");

printf("\nlianghao");
else
if(90<=x<=100)
printf("\ngood");}

printf("\nnrror");

printf("input one number:");
scanf("%d",&x);
if(60<=x<=69)
printf("\njige");

/* Note:Your choice is C IDE */
#include<stdio.h>
main()
{int x;
printf("input one number:");
scanf("%d",&x);
if(x>=60 && x<=69)
printf("\njige");
else
{else if("x<=70 && x<=89)
printf("\nlianghao");
else
if(x>==90 && x<=100)
printf("\ngood");}
else
printf("\nnrror");
}
应该这样,是小错误,你是太粗心了/?
if(60<=x<=69)
if(x>=60 and x<=69
应该是if(x>=60 && x<=69)
&& 且
|| 或
!= 不等于
#include<stdio.h>
main()
{int x;
printf("input one number:");
scanf("%d",&x);
if(60<=x<=69)
printf("\njige");
else
{else if("70<=x<=89) //这里不应该有else了
printf("\nlianghao");
else
if(90<=x<=100)
printf("\ngood"
