As the title states, I have a problem where all the comparison operators are generating an error. The assignment explicitly states that no arguments are passed to the function. What should I do here on out? Any help would be appreciated. Thank you.
It usually means that the linker can't find a function with the proper signature. Make sure your function prototype, function implementation and function call all agree as to the number and types of parameters.
By the way the error messages usually will tell you exactly what the problem was so in future post the complete error messages, all of them exactly as they appear in your development environment. Then perhaps someone can help you decipher the error messages. And note that one error may generate multiple messages, which can help pinpoint the actual problems.
