这个c程序哪里错了？？？？？

Question

#include
int main(void)
{
const int danjia = 5;
int shuliang = 0;
int zongjia = 0;
int zan = 0;
printf("shurushuliang:");
scanf("%d",&shuliang);
zan = shuliang * danjia;
{
if((zan > 30) && (zan <= 50)）
zongjia = shuliang*danjia*0.1;
printf("%d",zongjia);
if(zan > 50)
zongjia = shuliang*danjia*0.15;
printf("%d",zongjia);
else
printf("%d",shuliang*danjia):
return 0:

}

}

就是提示出错，但我就是找不到哪里错了。。。。。

Answer 1

丢大括号，还有分号写成冒号

 const int danjia = 5;
int shuliang = 0;
int zongjia = 0;
int zan = 0;
printf("shurushuliang:");
scanf("%d",&shuliang);
zan = shuliang * danjia;

if((zan > 30) && (zan <= 50))
{
zongjia = shuliang*danjia*0.1;
printf("%d",zongjia);
if(zan > 50)
zongjia = shuliang*danjia*0.15;
printf("%d",zongjia);
}
else
printf("%d",shuliang*danjia);
return 0;
