ERRORS and It's Types

By -


Error are the most important term in programing...
Every beginner as well as professional programmer should face the problem of errors.

There error can be defined as

 " Error is not getting a genuine result due to mistaken instruction. "

Or 

" These are the simple mistakes which leads to not getting correct results or may be program will not execute "



In Book or in Internet you can find out many types of errors but all errors are similar to or slightly different from each other...
but there are only THREE TYPES OF BASIC ERRORS  i.e,

1- Syntax Error / Compile Time Error 
2- Run Time Error 
3- Logical Error / Semantic Error


Syntax Error -
- These are the errors, when grammatical rule of C++ (any language) is not followed.
- There errors are shown at the time of compilation.
- It is also called Compile time error.

Eg- Syntax of for loop
        for ( ;  ; )
       {
        }  // this is correct

        for ( ;  ; ) ;
       {
        }  // this is incorrect

Run Time Error -
- These are the errors which occur at the time of program execution.
- These errors are shown at the time of execution.

Eg- a) Dividing by zero
       b) Type mismatch


Login Error -
- These error occur when logic is incorrect but syntactically the statement is correct.
- It is also called Symmetric errors.
- Login error can't be seen , it leads to wrong result.

Eg- both are correct
if(x==y)     // compare the value of x and y.
if(x=y)       // value of y copies to x.

Include Vs Import

There are two terms IMPORT and INCLUDE ,  In C and C++ Programs ,  Include Statement is used #include directive makes the compiler go to the C/C++ standard library  It copy the code from the header files into the program.  The whole include file code will copy into the program  As a result, the program size increases wasting memory and processor’s time.  In Java Programs , Import  Statement is used import statement makes the JVM(Java Virtual Machine) go to the Java standard library, execute the code there ,  and substitute the result into the program.  Hence, no code is copied hence no waste of memory and processor’s time. Hence import is more efficient mechanism than #include. By - Somesh Sah

Object Oriented Program (Paradigm)

Paradigm - It is a mythology and implementation of the program. (It is a way of programming) Therefore, There are three ways (Style) to write a program - ♣ Procedural Programming  ♣ Object Based Programming ♣ Object Oriented Programming  Procedural Programming -  ☻ Importance is given to the procedural (Function and Methods) ☻ Data is secondary ( data moves openly) ☻ It follows Top-Down Designing. Example - Basic and C  Object Based Programming - ☻ These languages support Classes  ☻ These languages does not support Inheritance and Polymorphism    Example - ada Object Oriented Programming - ☻ These language support all the mentioned features Encapsulation Abstraction Polymorphism Inheritance ☻ Data is hidden ☻ It follows bottom up design  Example - C++ , Java etc. Now, Object Oriented Programming (OOP's) in detail  DEFINITION OF OOPs " O...

Call By Value & Call By Reference

By -

FORMAL PARAMETER - These are the parameters which appear in the function definition or declaration is called Formal Parameter.  ACTUAL PARAMETER - These are the parameters which appear in the function call is called Actual Parameter. Call By Value - In Call By Value , value of actual parameter is copied into Formal Parameter. The function work on formal parameter only. Actual parameter is intact. Change are not reflected is called function. Call By Reference -  In this type, instead of copying a value of actual parameters into formal parameter, the function receive address of the actual parameter. Works on the original value, Changes are reflected in the calling function. Summary -    By - Somesh Sah
