used is not recognised by the compiler. This is usually because the programmer has either made a simple typing slip, or because he or she has not completely understood the rules of the language as they apply to https://www.macs.hw.ac.uk/~pjbk/pathways/cpp2/node123.html the programming construct. In some sense, compile time errors are the easiest to correct, because they always result in an error message. Unless the error is so severe that the compiler cannot continue, the translation process will continue with the possibility of detecting further errors. It is possible that the errors detected are not ``genuine'' errors, but consequences of earlier errors. A simple example of this is the problems caused if there is an error time error in the declaration of a variable. The compiler will not recognise the variable as such when it is used, and it will complain about `` Undeclared variable''. In order to recover from this, many compilers make some assumption about the variable and continue, so that other errors can be found. Typically this will involve assuming that the variable has been declared of type int, and continuing. This assumption may itself cause further compilation errors if an compile time error int variable is not acceptable. A common cause of apparently correct programs causing compilation errors is a comment which is not terminated correctly. Apart from the // comment which terminates at the end of the line, C++ supports a comment that starts with /* and extends until a matching */ character pair. Omitting the closing */ causes havoc! Similar problems occur with missing quotation marks on strings " or characters '. Typing errors in variable identifiers and keywords can be difficult to spot: watch out for confusion between the letter l (el) and the digit 1 (one). Other characters that often cause errors, particularly when transcribed from handwritten notes are z and 2, s and 5, and o and 0. The compiler also distinguishes between upper and lower case letters. It is not good practice to have identifiers which only differ in the case of some letters. A good strategy for dealing with compile time errors is to identify the first error reported. Once the first error is identified, usually either in the statement in which it is reported, or possibly the previous statement, one can attempt to decide which errors are consequences of that error. These can safely be ignored. Errors which cannot be explained in this way should be investigated too. Once as many as possible of the errors have been corrected,
