Basically the program will ask the user to select a number from 1-8(all numbers are in pairs), and when the user keyed in the value, the program will select the nearest number it encounters and mark the number.
example:before the user enters a value.
# # # # # # # # # # # # # 1 2 # # 4 # # 6 2 8 # # # # 1 3 5 # # # # 3 6 # # 4 5 # # 7 # # 7 8 # # # # # # # # # # # # #
After the user enters a value, assume the user enter number 1 as the value.
# # # # # # # # # # # # # [1] 2 # # 4 # # 6 2 8 # # # # 1 3 5 # # # # 3 6 # # 4 5 # # 7 # # 7 8 # # # # # # # # # # # # #
These are my codes, but the selectnumber function is not working, when i runs the program it just crashes.
