What type of error is a violation of the rules of a programming language?
Finally you will run the object file to obtain the output. You will probably produce a program listing which is a printout or soft copy of the source program instructions as a reference while working and coding the program. Show When the computer is interpreting or compiling a program that is your source code, an error, whether major or minor will cause it to either produce (output) results or not reach the stage of output at all. There are different types of errors which will cause your program to ‘crash’. We will be looking at some of these errors: v Logic errors Logic errors occur when the programmer makes mistakes in the sequence of the program statements such using the wrong formula or function ( ie using a MOD instead of SQR FUNCTION). The program will usually compile that the compiler converts the source code to object code. NOTE: that compilation with logic errors does not generate any syntax errors or any warning messages but when the program is run it produces the wrong results. v Syntax errors Syntax errors occur when a mistake is made in the programming language rules or violating the rules governing the structure of the language. In short a syntax error occurs when the programmer fails to follow the rules of the programming language exactly. For example if a keyword such as input or print is spelt incorrectly or an endif was left out. v Run-time errors or execution errors Run-time errors occur as the program compiles or runs. These errors are usually due to unexpected events such as division by zero or lack of memory for the computer to manipulate the data or a loop with no end. Run-time errors can be very difficult to trace as the program may produce results most of the time. Example: for x = 1 to 3 Result = result/(average-1) when average is equal to 1 you will be dividing by zero, this cause the computer to hang-up or an error message will be produced. v Debugging Debugging is the process of finding errors in the source code (detection), understanding why they occurred (diagnosis) and correcting them. Errors are found through error messages generated by the program or the operating system or because the program does not behave as expected. TESTING ALGORITHMS Desk checking or dry running is the process of checking an algorithm for errors. You do this by pretending to be a computer and executing the steps in the algorithm one by one, while keeping a record or track of the results. Trace table is a very useful tool which allows you to see the state of your algorithm with as much details as you wish. Each row of the table shows the state of one step in the algorithm and each column shows the value of a variable at that step. The trace table allows you to check the algorithm for errors. For example: Complete the trace table for the following algorithm, given that the number 4 is the input value for X Read X FOR M = 1 TO X DO Y = X-M Z = 5*Y- M END. PRINT Z X M Y Z 4 4 4 4 Testing As you complete your program, you must ensure that it works for any correct input data that the user gives it. The testing phase is to detect errors or problems in the program. Test data: the values that are used to test or check the correctness of the program. The test data should include a wide range of sample data including extreme values and inputs that are not valid. Structured walk through: This is the process of performing a manual trace on the program to detect any possible errors. Executing the program If you have translated the program to its object code without errors, you can now execute the program and see the results. The final two terms commonly used with program execution are: saima jabeen answered There are the following errors can occur:

Logic Errors.. Compilation Errors.. Runtime Errors.. Arithmetic Errors.. Resource Errors.. Interface Errors.. What are programming language errors?Errors are the problems or the faults that occur in the program, which makes the behavior of the program abnormal, and experienced developers can also make these faults. Programming errors are also known as the bugs or faults, and the process of removing these bugs is known as debugging.
Which kind of error occurs if the rules of programming are not followed *?Syntax Error
In other words, syntax errors occur when a programmer does not follow the set of rules defined for the syntax of C language. Syntax errors are sometimes also called compilation errors because they are always detected by the compiler.
