You can look at this code, hope to adopt

``````#include
using namespace std;
int main() {
float a;
cin >> a;
float b = a * 0.6;
int c = b / 1;
float d = b - c;
cout << c << " " << d * 10 <return 0;
}
``````

Part of the answer quotes GPT, GPT_Pro to better solve problems
Questions about C++, simple electricity problems, You probably mean how to implement a simple electricity calculator in C++?

First, we can define a function to calculate the cost of electricity:

``````double compute_electric_fee(double quantity, double price){
return quantity * price;
}
``````

Then, we define a main function that calls the above function:

``````int main(){

// 测试一组数据：用电量为100度，1度电价为1.5元
double quantity = 100;  // 用电量
double price = 1.5;  // 1度电的价格

double electric_fee = compute_electric_fee(quantity, price);  // 计算电费

cout << "the electric fee is: " << electric_fee << endl;  // 输出电费

return 0;
}
``````

The above code implements a simple test. When we have multiple sets of test data, we can use a loop to put them all into an array, then iterate through the array to test all the data, and print the result:

``````int main(){

int size = 5;  // 测试数据的组数

// 定义一个二维数组来存储所有测试数据：[[quantity1, price1], [quantity2, price2], ...]
double data[size][2];

// 填充测试数据：[[100, 1.5], [200, 2], ...]
data[0][0] = 100; data[0][1] = 1.5;  // 第一组测试数据：用电量100度，1度电价为1.5元
data[1][0] = 200; data[1][1] = 2;  // 第二组测试数据：用电量200度，1度电价为2元
// ...

for (int i=0; i<size; i++){  // 遍历测试数据集

double quantity = data[i][0];  // 获取当前测试的用电量值
double price = data[i][1];  // 获取当前测试的1度电价格

double electric_fee = compute_electric_fee(quantity, price);  // 计算电费

cout << "the electric fee is: " << electric_fee << endl;  // 输出电费

}

return 0;
}
``````

Through the above steps can achieve a simple C++ electricity calculator. In practice, we may also need to consider other factors, such as monthly minimums, coupons, different prices for different forms, summer surcharges, and other factors that may affect the final fee. These factors should be based on the actual situation to adjust the code.
