Question

下面的代码编译不过，可以告诉我是什么原因吗？

#include<inttypes.h>
#include<math.h>
#include<stdio.h>
int main(void)
{
uint32_t profit = 0;
uint32_t reward = 0;
uint32_t temp = 0;
printf("please input the profit:\n");
scanf("%d",&profit);
if(profit < 10)
{
reward = profit * 10%;
}
else
{
temp = 10 * 10%;
profit = profit - 10;
if(profit < 10)
{
reward = temp + profit * 7.5%;
}
else
{
temp += 10 * 7.5%;
profit -= 10;
if(profit < 20)
{
reward = temp + profit * 5%;
}
else
{
temp += 20 * 5%;
profit -= 20;
if(profit < 20)
{
reward = temp + profit * 3%;
}
else
{
temp += 20 * 3%;
profit -= 20;
if(profit < 40)
{
reward = temp + profit * 1.5%;
}
else
{
temp += 40 * 1.5%;
profit -= 40;
reward = temp + profit * 1%;
}
}
}
}
}
printf("the total reward is : %d\n",reward);
return 0;
}

Answer 1

C++里面没有诸如10%、1.5%这种写法。可以写成0.1、0.015试试。
