这是我的代码

Hello all,

I would like to find the total value of sales during a specific month by each department and in each stores?

I'm having hard time to get total sale value for specific month by each department and in each stores.
Can Someone please help me in this matter

Thank you for taking the time to help.


Here's my code

#include <iostream>
//defining the following global variables
#define NUM_DEPTS 2
#define NUM_STORES 2
#define NUM_MONTHS 12


using namespace std;

//Description: Creating a function to calculate and print the total value of sales
//during a specific month by each department and in each store.
//Pre-condition: We need two parameters array sale, and month. 
//Post-condition: After calling the function inside the main we get the total value of sales 

void  sales(float sale[][NUM_STORES][NUM_MONTHS],int Month);

//Description: Main function where program begins
int main(){
	int Month;
	//Creating three dimensional array of float-point type 
	float sale[NUM_DEPTS][NUM_STORES][NUM_MONTHS] =
	{ 1.1, 1.2, 1.3, 1.4, 1.5, 1.6, 1.7, 1.8, 1.9, 2.0, 2.1, 2.2,
	2.1, 2.2, 2.3, 2.4, 2.5, 2.6, 2.7, 2.8, 2.9, 3.0, 3.1, 3.2,
	3.1, 3.2, 3.3, 3.4, 3.5, 3.6, 3.7, 3.8, 3.9, 4.0, 4.1, 4.2,
	2.1, 2.2, 2.3, 2.4, 2.5, 2.6, 2.7, 2.8, 2.9, 3.0, 3.1, 3.2,
	};

	system("pause");
	return 0;
}


void  sales(int sale[][NUM_STORES][NUM_MONTHS], int Month){

	int sum = 0;
	
	//creating Three for loop to get the total value of sale 
	for (int i = 0; i < NUM_DEPTS; i++){

		for (int j = 0; j < NUM_STORES; j++){

			for (int k = 0; k < NUM_MONTHS; k++){
				sale[i][j][k];

				cout << "The total sales value " << sale[i][j][k] << endl;


			}
		}
	}


}

推荐答案

答案在你的循环中看起来很容易：

The answer looks so easy in your loop:

sum += sale[i][j][month]; //only use the montth
cout << "add sales value " << sale[i][j][month] << endl;

但是想想结构或类更好的解决方案。作为一些数据结构：

But think about some better solution with structs or classes. As some data structure:

struct {
  int department;
  int stores;
  int sales;
} MONTH;

它有助于整理和清理数据

it helps to organize and clearify data
