First past the post election program I want this progrram to:
1. Obtain the number of votes for each candidate2. Display the number of votes awarded to each candidate3. Display the total number of votes cast
I’ve highlighted the bits I’m having problems with I’m a beginner to Javascript and its a bit of a struggle at the moment. I have done as much of the code as I can however, I just need some advice. Thanks in advance.
