Hi. I need help with the code for a fish race
The question I was given is as follows:
*You are asked to design a “Fish Race” game. Two fishes of different colors and shapes will race until one of them reaches the race’s end line. Your program should display a message at the end of the race showing which fish has won the race. To win the race, three fishes from the same type should reach the end line. When one of the fishes reaches the end line, another fish from the same type and color of the winning fish starts moving again towards the end line. Your program should display two counters at the top of the screen showing how many fishes have currently reached the end of line.
Note that each fish will be on a separate row (line) and each fish will move horizontally in random steps (each random step can only be between 1 and 4 steps).
*
My problem is that the fish aren't moving towards the finish line. Only the first fish moves and that too just one step.
Before one fish atleast was able to cross the finish line but then my VS crashed while I was making changes to the code and I can't figure out what I changed.
So below is the code. I hope somebody can help me please
