Carrying out a c++ 2d array - c++

Question

My array is supposed to accept 3 values for 3 salespersons, store and print the array but somehow I can't get it going. I'm not too familiar with c++ 2d arrays so this is a tad bit new to me. The code is supposed to accept user input, and then output the prices of the products into table like format.

I had to clean up a lot of code to get this to even begin to compile. There were many cases where the closing } of a block was not present. These mistakes are easy to make, but they're also easy to spot if you're disciplined about maintaining a consistent indentation style.
Once I indented the code it became fairly obvious where the errors were, but identifying these in the original is very hard.
Here's the cleaned up code:
#include <iostream>
#include <iomanip>
int main( ) {
const int salesPersonCount =3, productCount = 3;
int rows = 5, columns = 5;
int sales[rows][columns];
double total;
for (int p = 1; p <= salesPersonCount; p++) {
std::cout << "\n \n Information for SalesPsn"<< p <<" : \n \n";
//Sales Person
for (int m = 1; m <=productCount; m++) {
//Product Number
std::cout << "\n Please enter sales value of product "<< m << ":";
std::cout << "\n ";
for (int i=0;i<rows;i++) {
for (int j=3;j<columns; j++) {
std::cout << "\nThe 2-D Array is:\n";
for (int i=0;i<2;i++) {
for (int j=0;j<2;j++) {
std::cout << "\t" << sales[i][j];
}
std::cout << "Sale " << std::setw (17) << "Salespsn1" << std::setw (22)<< "Salespsn2"
<< std::setw (27)<< "Salespsn3" << std::setw (32) << "Total" << std::endl;
}
std::cout << std::endl;
}
}
}
}
return 0;
}
Note this still has a lot of problems you're going to need to resolve, like how you're capturing sales and information into variables p and m which are also used for iterators, plus how nothing actually puts data into the sales structure, but at least you've got something you can fix.
My advice: When you get into a deep hole, stop digging. If you can't figure out what to do, clean up your code. I've solved many problems in the course of better organizing what I've done, in adding comments to parts that should work yet don't. There's no shame in being stuck, but if you're stuck because of a mess you didn't clean up that's on you.

I went over the code and this is the final product... Turns out no input was needed I was overthinking. Thanks for the help #tadman For anyone who is interested:
#include <iostream>
#include <iomanip>
#include <string>
#include <stdio.h>
#include <math.h>
#define ROW 3 //number of rows
#define COL 3 // number of columns
//Function Prototype section
void enterItems(double salesArray[][COL]);
void getRowTotal (double Sales[][3], double total[][3]);
void getColTotal (double Sales[][3], double total[][3]);
void DisplayArray (double Sales[][3], double total[][3]);
using namespace std;
int main (){ //function main begins program execution
//storing 3 sales person and 3 different product
//Declares Arrays
double Sales[ROW][COL] = { {250,200,300 }, {500,350,220 },{150,600,450 }};
double total[2][3] = {0};
//Calls Functions getRowTotal, getColTotal and DisplayArray
getRowTotal (Sales, total);
getColTotal(Sales, total);
DisplayArray (Sales, total);
//Signifies that program is successfully executed
return 0;
}
//variables
int z = 0, j = 0;
//Declares And Defines getRowTotal
void getRowTotal (double Sales[][3], double total[][3]){
for(z = 0; z < 3; z++)
total[0][z] = Sales[0][z] + Sales[1][z] + Sales[2][z];
}
//Declares and Defines getColTotal
void getColTotal(double Sales[][3], double total[][3]){
for(z = 0; z < 3; z++){
total[1][z] = Sales[z][0] + Sales[z][1] + Sales[z][2];
}
}
//function DisplayArry
void DisplayArray (double Sales[][3], double total[][3]){
//Table Headings
cout << left << setw(10) << "Title" << setw(15) << "SalesPerson1 " << setw(15) << "SalesPerson2 " << setw(15) << "SalesPerson3 " << "Total";
cout << "\n_______________________________________________________________________________________________\n";
cout << fixed << setprecision(2) << showpoint;
//Displays the Sales and row headings
for(z = 0; z < 3; z++){
cout << setw(8) << "Product " << z + 1 << setw(1) << " ";
for(j = 0; j < 3; j++)
cout << setw(17) << Sales[j][z];
cout << setw(17) << total[0][z];
cout << endl;
}
cout << setw(8) << "Total";
for( z = 0; z < 3; z++)
cout << setw(19) << total[1][z];
cout << "\n_______________________________________________________________________________________________\n";
