老实说，这是一个家庭作业。但是我已经花了 2 天，没有得到任何结果。我不擅长编程，但它是一个强制性模块。
问题需要先用typedef构建一个struct，然后用struct写一个函数来收集信息，并使用指针方法。
下面是代码，仅包括结构和函数部分，用于我自己仍然想做的其他事情。请相信我，我已经尽力做到了
//Assignment.cpp
#include <stdio.h> //Pre-define in question, can't change
#include <ctype.h> //Pre-define in question, can't change
#include <stdlib.h> //Pre-define in question, can't change
//Requirement: Use typedef to create a struct called Car
typedef struct Car{
float price;
unsigned int numofmonth;
unsigned char member;
}Car;
Car *p
struct Car customer1;
struct Car *p=&customer1;
//Function phototype
void collectInfo(Car *p); //pre-define in question, can't change
void printInfo(Car p); //Pre-define in question, can't change //Once the Collect info part done, I will do it myself
int main(){ //Pre-define in question, can't change
Car customer1; //Pre-define in question, can't change
collectInfo(&customer1); //Pre-define in question, can't change
printInfo(customer1); //Pre-define in question, can't change
system("pause"); //Pre-define in question, can't change
return 0; //Pre-define in question, can't change
}
//Function defintions // The problem I want to ask, how to make it work? Thanks
void collecInfo(Car *p){ //Pre-define in question, can't change
for(int i = 0; i < 3;i++){
printf("Price of Car : ");
scanf("%d",&customer1[i].price);
printf("Perferred Months for Installment : ");
scanf("%d",&customer1[i].numofmonth);
printf("Perferred Months for Installment : ");
scanf("%c",&customer1[i].member);
printf("\n");
}
}
谢谢你们的评论。
其实这是一个关于“贷款计算”的问题。要求是使用typedef、struct、指针和函数来完成程序，我对指针只有一个简单的想法。据我所知，这是为了永久解决问题。
这是完整的问题和我到目前为止所做的代码。
问：有以下要求，做一个汽车安装程序，如下面的屏幕转储：
价格
分期月数（只能选择24或36个月，请输入验证）
如果客户加入会员。
变量： - 24 个月的利率为 10%
36个月利率为15%
如果加入会员，可一次性退还 3000 美元的总贷款
第一个月还款额为总贷款的20%
示例屏幕转储：
车价：30000
分期付款的首选月份：36
您是否加入我们的会员（是/否）：是
==================
打印详细信息：
==================
贷款总额：31500
第一个月付款：6300
月供：700
下面是我现在还在做的代码

scanf("%u",&(p->numofmonth));
if(p->numofmonth == 24)
interest=0.1;
else if(p->numofmonth == 36)
interest=0.15;
else
printf("Sorry, we only accept 24 or 36 months installment");
printf("Are you our member (y/n) : ");
scanf("%u",(p->member));
//check if the member = y or n
if(p->member == 'y')
lumpsum=-3000;
else if(p->member == 'n')
lumpsum=0;
else
printf("Please only input 'y' or 'n'");
printf("\n");
}
//Show result on screen, still doing, have problem to display result of pointer...
void printInfo(Car p){
printf("Price of the Car: %.2f\n", customer1.price);
printf("Preferred Months for Installment : %u\n", customer1.numofmonth);
printf("Are you our member (y/n) : %u\n", customer1.member);

}
经过大量的谷歌，我尝试在函数 collecInfo 中使用 malloc
