Literal constants are fixed values that do not change during the execution of a program, such as numbers (e.g., 5, 3.14) or strings (e.g., "Hello"). Symbolic constants, on the other hand, are named identifiers that represent a value, which can improve code readability and maintainability; for example, using PI to represent the value of 3.14. While literal constants are directly written in the code, symbolic constants are defined using keywords or specific syntax in programming languages, often in uppercase to distinguish them.

What is the difference between a symbolic and a literal constant?
A symbolic constant is a variable that is assigned a fixed value that cannot be changed during the program's execution, often represented by a name that conveys its meaning (e.g., PI = 3.14). In contrast, a literal constant is a fixed value directly embedded in the code, such as 3.14 or "Hello", which does not have an associated name. Symbolic constants improve code readability and maintainability, while literal constants provide immediate values without the need for additional identifiers.
What are Advantage of use symbolic constant?
Using symbolic constants in programming has several advantages. Firstly, they enhance code readability by providing meaningful names for values, making it easier to understand the code's purpose. Secondly, they improve maintainability, as changing a constant’s value in one place automatically updates all occurrences, reducing the risk of errors. Lastly, symbolic constants help prevent "magic numbers," promoting better coding practices and making it easier to manage changes in the future.
What are constants and how are they are different from variables?
Variables change, constants do not.
Why do constant constants have units?
Constants in the sense you mean are different to mathematical constants. They usually refer to a system in which two values are proportionate and so are of the units associated with the system.
Do all proportionality constants have no unit?
No, not all do. The proportionality constants that change the units will have units themselves.

What is symbolic constants?
Symbolic constants are constants that the programmer has decided to give a symbolic name (usually one with a meaning to make it easy to remember) so he does not have to retype the numeric value every time he needs it and risk making an error. Many coding standards require ALL constants to be symbolic constants, even if only used once in the program.
What are symbolic constants?
A symbolic constant is a constant with a name, numeric constants are unnamed and must be retyped in the code on each usage. Generally use of symbolic constants is preferred as it makes the code self documenting and allows the compiler to catch typing errors in constant usage.
What is the definition of symbolic constants in c language?
constants are values that does not chnage through out the program exceution..
What is the difference between name constant and literal constant in c plus plus programming?
a named constant is pretty much the same thing as a literal constant, except it is a name. both cannot change. literal constants are numbers, named constants are words. tada!
