I need help with the following c++ code. An explanation of the logic used to solve the problem will also be appreciated either with a flow chart or in words.

This last one is the same except the triangle needs to be displayed to the right.

3.2 Code Write a C++ program in a file named main3.cpp (using the algorithm from your flowchart) that reads in one positive integer value, q, from a file called input3.txt and writes to a file called output3txt a right-angled isoceles triangle of base length q made of asterisks. The hypotenuse must face the right, with its side on the left For example your input file may contain the value 7: Listing 8: Example of input3.txt
