Difference Between Compiler Error & Compiler Warning | Lesson-14 | Learn C Programming

This video talks about compiler warning, compiler error their differences.

In this lesson, to give examples of compiler warning and compiler error, I will be writing flawed code in C so that it the compiler throws an errors or warnings and with the help of those we will be understanding the difference between compiler warning and compiler error in C.

I would request you to write a book on c language and publish it soon

compiler warning: warnings are minor mistakes which could compile and generate a binary file, warnings can be generated when user program in a unstructured way and unsupported features, where compiler tells the programmer to modify to give the expected result.
Compiler error: this is a major issue in a program which defines a syntax error or a not recognised character in the program, and doesn't get compiled and doesn't generate binary file.
Thanks sir

[nitish]

Compiler error : I won't show your result until you rectify your mistake.
Compiler warning : Do as u wish. Iam letting you to fall in mudpit, your appearance after crossing mudpit is based on your fate..

Thank you for such informative class sir❤️❤️

Warnings is allows user to run source code and binary file generated ....whereas compile time error means compile time failure in code n no binary file generated for source code .

[palanibhavesh]

Q:- What is the difference between compiler error and compiler warning? Write it in your own words.
A:- Compiler produces Compiler Warning ⚠ :
--- if we have used any obsolete features (outdated features or unsupported features) in our C - source code (or)
--- if we have written our C - source code in some unusual way or using some improper standard procedure for writing code or different than what is actually
recommended..
Then in above said instances we get compiler warnings.
* The Binary file or Executable file(.exe ) is generated by the compiler even though we get compiler warnings.
Eg: If we don't use <stdio.h> header file then we can still get the output using printf() statement but with a compiler error.

Compiler produces Compiler Error :
--- If there are syntax errors like missing a semicolon( ; ) at the end of a statement in the code.
* Unlike compile warnings, in compiler errors the compiler does not generate the binary file or executable file until the generated error is resolved.

[bhanuprasannareddy]

In my point of view errors are occurred in program code .If we done any mistakes while coding it will give an error.
Warning :means we are successfully run the program but Warning occurs at final result of the program execution

[devaarasi]

When we run any program, which results in compiler warning will be capable of creating a binary file, but same program which is occured by compile time error doesn't create a binary file

[kcankith]

After a compilation when we get a "warning" we can generate a binary code whereas when we get a "error " we cant generate a binary code.

[sameerak]

compiler warning: source code allows our program to compile and it also generates a binary file.
compiler error: It doesn't allow our program to compile and doesn't generates any binary file .

[s_hilpa]

Compiler Warning:
•The compilation gets completed successfully.
•The binary file is generated.
Compiler Error:
•The compilation is a failure.
•Binary file is not generated.

[Thenmozhibca]

Compiler Warning :
✓ Programmer uses obsolete feautures or in use of non - standard features of standard C there exists a Compiler Warning.
✓In which, Binary file has been generated eventhough there is a Warning !

Compiler Error:
✓ The Programmer might have use wrong Syntax or missing vocabulary like }, ; etc..
✓In which, Binary file has not be generated until if it is free of Error.

[diptijadhav]

Sir slide get blur for 1 or 2 minutes is it due to poor network...?

[kasimanvenky]

Compiler warning:Whenever you will allow the source code and run the program. Then the binary file will be generated.
Compiler error: whenever you will run the program then will get compiler time error. Then you will rectify that error and compile the program then only binary file will be generated this is called compile time error.

[sasmitadas]

Compiler warning: Allows to run our program
Binary file is generated but does not guarantee desired output
Compiler error: Doesn't allow to run our program
Binary file is not generated.
It indicates wrong syntax.

[dhanyam]

Warning ⚠️ allows the program to run and generate it's binary code whereas errors will not allow the program to run and the binary code will not be generated until the error is rectified.

[keerthanaravishankar.]

Complier warning : is given the result.but danger point of the program
Complier error : is not given the result for the program

[shreyamukkawar]

Compiler Warning:
Warnings may indicate danger points where you should check to make sure that your program really does what you intend
Compiler Errors:
You get compiler time errors when the compiler realises that the programmers has used wrong vocab of C language while writing the C source code.

[abhishekgoswami]

Compiler Warning:
It still allows compile the program and so that its binary file to be generated
Compiler Error:
It doesn't allow to compile the program and so that its binary file

[jesuspresence]

Compilation is successful and generate binary file is known as"compiler warnings".
Compilation is not successful and can't generate binary file is a " compiler errors"

[priyangam]

Compiler Warning:
Source code successfully compiled by compiler and binary file will be generated
Compiler Error:
Compiler won't generate the source code and binary file won't be generated
