C++ Help with Sorting in my code. Create functions to sort the array.

I need to sort the the .txt input and output it in a certain way that's in the examples below. It's already in arrays from the code, could really use help with sorting it.. Need main to keep main as clean as possible so need some functions, if necessary. Please add comments so i know what's going on.

Each input line has 4 attributes(num, color, shading, shape) To be considered a group, three input lines either have to match atleast 3 attributes(Examples below: Please Look at them before starting). Three input lines are also considered a group if none of their values match.

input line: num color shading shape

The numbers are ordered 1, 2, 3, the shading is ordered empty, striped, filled, the color is ordered brown, orange, yellow, and the shapes are ordered circle, square, triangle.

Each group is output by first sorting the cards in the group, and then printing out each of the cards in the group (using the same format as the input file) separated by a period and a space.

One group is output per line, and the groups are ordered based on the first input line in the group, then the second, and then the third.

Example

For this example, the input file input1.txt contains:

2 filled orange circle

1 empty yellow triangle

2 empty orange circle

3 filled brown square

1 striped yellow triangle

2 striped orange circle

1 empty brown triangle

3 empty yellow square

1 filled orange triangle

And the input file input2.txt contains

2 filled brown triangle

1 striped yellow square

1 filled brown triangle

3 filled yellow circle

Empty Striped Filled

Output from the program should look like the following (inputs are in blue text):

Enter the set input file name (or done to terminate the program):

textfileB.txt

1 empty brown triangle. 1 striped yellow triangle. 1 filled orange triangle

1 empty brown triangle. 2 empty orange circle. 3 empty yellow square

1 empty yellow triangle. 2 striped orange circle. 3 filled brown square

1 striped yellow triangle. 2 empty orange circle. 3 filled brown square

2 empty orange circle. 2 striped orange circle. 2 filled orange circle

Enter the set input file name (or done to terminate the program):

textfileB.txt
