Errors in a Code

Hello guys, you must have been, so far doing all the zig-zag with keyboard to compile your program. But sometimes you may encounter some errors, to which you would have nod your head up to your code without even trying to understand what exactly was the problem, right?

Well today we will discuss about, how missing out the tinniest thing which plays a great role in compilation of your code.

                    Errors in C / C++ / Java Language

There are total three types of error in these languages :

1)   Compile Error

2)   Run Time Error

3)   Logical Error

Compile Error:

These errors present themselves on the output screen at the time of compilation of the program. They can be classified into two

                         1. Syntax Error :  When you break out the rule of the C programming language, our compiler will show Syntax Error.

Eg, int a,b:

This will produce syntax error as the program is terminated by : rather than ;

             2. Semantic Error :  This error presents himself to the compiler when the statements written in the program are not meaningful to the compiler.

For eg,     b+c=a;

In the above statement we are trying to assign value of a in the value obtained by summation of b and c which has no meaning in c. The correct statement will be

a = b+c;

Run Time Error:

Due to some illegal operation performed in the program give rise to run time errors that occur during the execution of the program.

Examples of some illegal operations that may produce runtime errors are:

• Dividing a number by zero
• Trying to open a file which is not created
• Lack of free memory space

Occurrence of these errors may stop program execution, so to encounter this, programs should be written such that they are able to handle such unexpected errors and rather than terminating unexpectedly, they should be able to continue operating. This ability of the programs is known as robustness and the code used to make programs robust is known as guard code as it guards program from terminating abruptly due to occurrence of execution errors.

Logical Error

Logical errors are in the output screen as undesired output and are caused by the illogical way applied in the program to produce the desired output.

Also, compiler doesn’t detect this error, and thus, you have to check out your whole code, line by line.

Hope you all are clear on this now.
