C语言实现超市收银系统的设计与实现
在开始设计超市收银系统之前,我们需要明确系统的基本需求:
为了实现上述功能,我们需要设计以下数据结构:
以下是一个简单的C语言超市收银系统实现示例:
```c
include
include
include
define MAX_PRODUCTS 100
define MAX_CART_ITEMS 100
typedef struct {
int id;
char name[50];
float price;
int stock;
} Product;
typedef struct {
int id;
int quantity;
} ShoppingCartItem;
Product products[MAX_PRODUCTS];
ShoppingCartItem cart[MAX_CART_ITEMS];
int product_count = 0;
int cart_count = 0;
void add_product(int id, const char name, float price, int stock) {
if (product_count = quantity) {
cart[cart_count].id = id;
cart[cart_count].quantity = quantity;
cart_count++;
products[i].stock -= quantity;
break;
}
}
float calculate_total() {
float total = 0;
for (int i = 0; i < cart_count; i++) {
for (int j = 0; j < product_count; j++) {
if (cart[i].id == products[j].id) {
total += products[j].price cart[i].quantity;
break;
}
}
}
return total;
void print_cart() {
printf(
