Shooting competition
Hello people! I need help with an exam task that I can not handle ... I'm new to programming and I have no idea how to do it. I'll be grateful for your help! Here's her task:
Console application (without input from the console - possibly with arrays with fixed application data). At a shooting competition that takes place once a year, there are up to 30 contestants. For each individual competition, a stand-alone list of participants information is made. Each athlete is described with the name, PIN and points he receives (eg Ivan Ivanov - 1234567890 - 60). Competition data was entered in 2015, 2016, and 2017. Provide information - for the competition with the highest total number of points and the competition with the lowest total number of points. - the competitor (s) with the highest total points for all years.

¿race?

¿for each year or you make a weighted average?

Sorry! Broken English... The same competitors for all years. For example, John Dow with maximum points for 2015 + 2016 + 2017.

What is wrong in this code???

¿why are you asking? ¿does it solve your problem?
the code is quite convoluted and doesn't have a single comment, not going to analyse it.

so I thought it would make a decision on my assignment, but I'm mistaken... I would not want help here if I knew how to solve my problem myself...
Why don't you ask the one who gave you that code yesterday?
