Do comments use memory?
No they will Not occupy memory because they are not executing or taking part in running and compiling. Only after compiling the system will try to allocate memory as mentioned by the user,as these statements are not taking part in compiling system will not able to allocate memory.
What are comment lines in C language?
A comment starts with a slash asterisk /* and ends with a asterisk slash */ and can be anywhere in your program. Comments can span several lines within your C program. Comments are typically added directly above the related C source code.
Are comments considered lines of code?
Originally Answered: do comments count in source lines of code written? Yes they do. Comments line will not be interpreted by the server or client but will still affect the size of the final file. Normally comments should be used to explain specific parts of code, params,etc..
Are comments in C visible to compiler?
Comments are normally stripped out during preprocessing, so the compiler itself never sees them at all.
What language uses for comments?
Position of Comment Indicator
| Language | Comment Syntax |
|---|---|
| FORTRAN | C in position 1 |
| BASIC | REM at beginning of the line |
| COBOL | * in position 7 |
What type of comments does C Support?
C++ supports single-line and multi-line comments. All characters available inside any comment are ignored by C++ compiler.
Why comments are used in program?
In computer programming, a comment is a programmer-readable explanation or annotation in the source code of a computer program. They are added with the purpose of making the source code easier for humans to understand, and are generally ignored by compilers and interpreters.
Does the compiler ignore comments?
Comments are used to document what a program is for and how a program is constructed. Comments help the programmers or users to communicate and understand the program. Comments are not programming statements and are ignored by the compiler.
What information is important to write in comments?
Commenting involves placing Human Readable Descriptions inside of computer programs detailing what the Code is doing. Proper use of commenting can make code maintenance much easier, as well as helping make finding bugs faster. Further, commenting is very important when writing functions that other people will use.
What are comments in C programming language?
At run-time, a comment is ignored by the compiler. There are two types of comments in C: 1) A comment that starts with a slash asterisk /* and finishes with an asterisk slash */ and you can place it anywhere in your code, on the same line or several lines. 2) Single-line Comments which uses a double slash // dedicated to comment single lines
How do you comment out multiple lines in C?
The compiler will assume that everything after the /* symbol is a comment until it reaches the */ symbol, even if it spans multiple lines within the C program. You can create a comment that displays at the end of a line of code. In these examples, the compiler will define a constant called AGE that contains the value of 6.
What is a double slash comment in C++?
C++ introduced a double slash comment prefix // as a way to comment single lines. The following is an example of this: This form of commenting may be used with most modern C compilers if they also understand the C++ language. You can create a comment that spans multiple lines. For example:
What are comments and why are they important?
Comments are especially important in large projects containing hundreds or thousands of lines of source code or in projects in which many contributors are working on the source code.
