What is the difference between warning and error in C?
Errors report problems that make it impossible to compile your program. GCC reports errors with the source file name and line number where the problem is apparent. Warnings report other unusual conditions in your code that may indicate a problem, although compilation can (and does) proceed.
What does a warning in C mean?

What is the difference between a terminal error and a warning?
Normally you get an error message if the issue is terminal. This doesn’t necessarily mean the program completely stops just that a task did not complete. Warnings are used when the program detects that something didn’t look right but it didn’t cause a termination. Another description is that errors are fatal errors and warnings are not.
What is the difference between error and warning in compiler?
In the face of an error, the compiler cannot produce a translation of your program, because it isn’t a legal program — the compiler cannot figure out what to do. A warning occurs when your program is legal, and the compiler can produce object code for it, but something doesn’t look right.
What is an a warning in C++?
A warning occurs when your program is legal, and the compiler can produce object code for it, but something doesn’t look right. Examples include “control reaches end of non-void function” or “attempt to make integer from pointer without a cast.” If you get warnings, you get object code and you can get a program that you can run.
What is a syntax error in programming?
If that’s the context: An error occurs when your source is not a legal program. Syntax and type errors are typical examples: leaving out curly braces in a function definition, omitting a return type, or accessing members of an incomplete struct.
