Errors Check List

If you are struggling to understand your compile errors I will try to make a list here of the most common ones. This list can be updated as the course runs and we find the most common errors...

• VIEW Make sure you can view line number to help track down errors.
• VIEW Make sure you can view the error list (has to be turned on in VS).
• ERROR MESSAGES Try to interpret error messages from the compiler as best you can.
• CHECK Every statement ends with semi-colon ";".
• CHECK There is exactly one main function.
• CHECK Keywords are written in lower case.
• CHECK We have included all the required libraries.

• CHECK We have written at the top of the code the statement:

  using namespace std;

  or have prefixed all standard library data types and functions with std::

• CHECK Every open bracket is matched by a close bracket
• CHECK Function arguments are written in parentheses ()
• CHECK Code blocks are written in braces {}
• CHECK Array indices are written in square brackets []
• CHECK Every variable has been declared before it is used
• CHECK If we write int/int remember that it will return an int!!!
• CHECK Calculations by hand to see if the results are correct.
