Below is my home work problem. I don't want the answer, I am just looking for an example of how I can count the occurance of each number in the array numbers and assign that value to the count array.

*---------------------------------------…
* Sample Output:

*** start of 27610_Arrays03.cpp program ***

Number Count
1 1
2 2
3 5
4 2
5 3

*** end of 27610_Arrays03.cpp program ***

Input:
No data comes from the keyboard; all data, including the data
for the array, are contained within the program.

An integer array of 13 numbers: 3, 4, 5, 3, 2, 1, 3, 4, 5, 3, 2, 3, 5
An integer array of 5 counts intialized to all 0.
Compile-time arrays with initialization list of numbers.
NOTE: In main() function

Processing:
TODO #1: complete the coding of the numbers array

TODO #2: complete the coding to call the countValues() function
The values in the numbers array are counted
and the correct cells of the count array are increment.
Output:
TODO #3: complete the coding to call the display() function,
Display as shown in sample output.
Use iomanipulators to format output

TODO #4: complete the coding of the display() function
TODO #5: complete the coding of the countValues() function

what ideas do you have? Does not have to be code, just a general idea?

Since I can't read your code because of the lack of formatting I'll just give you a generic idea using

An integer array of 13 numbers: 3, 4, 5, 3, 2, 1, 3, 4, 5, 3, 2, 3, 5
An integer array of 5 counts intialized to all 0.

`counts[numbers[i]]++; // increment the count for number[i]`
