I need your help with my C++ program to find the Average Computation values and symbol for each city from the txt files and display them in the output. I managed to display the city name and id. You are not allowed to hard code as the coordinates and values can be changed. You are also not allowed to use vector for this if its possible. I have included the txt files and my codes below, you can edit in function3(). Refer to below for explanation.

readfile.txt

// The range of 'horizontal' indices, inclusive // E.g. if the range is 0-4, then the indices are 0, 1, 2, 3, 4 GridX_Range=0-8

// The range of 'vertical' indices, inclusive // E.g. if the range is 0-3, then the indices are 0, 1, 2, 3 GridY_Range=0-8

// [x,y] grid-areas which are occupied by cities city.txt

// each [x,y] grid-area cityValues.txt

Below is the diagram to aid your understanding.

Bright Yellow grid areas indicate the actual grid area occupied by a city.(e.g. [1,1])

Light Yellow grid areas indicate the grid areas surrounding the occupied city. For example above, the coordinate[2,8] has following grid areas surrounding its perimeter: [1,7],[1,8],[2,7],[3,7],[3,8].

The grid areas [1,9],[2,9],[3,9] are not shown as they are beyond the upper limits of the vertical grid range. As a result, they are not included in the Average computation. Refer to below for calculation.

For each coordinate listed in the city.txt file, the Average computation value is derived by the following: AC = SUM(city value + surrounding grid areas)/Total no of grid areas

For example, for the coordinate [2,8]: AC = (32 + (21+75+38+52+29))/6 = 41.17
