What is symbolic constant in C Plus Plus?

C++ has two types of constants: literal and symbolic. A literal constant is a value typed directly into your program wherever it is needed. A symbolic constant is a constant represented by a name, just like a variable. The const keyword precedes the type, name, and initialization.

Which section consists of symbolic constants?

– Link Section: The Link section provides instructions to the compiler to link functions from the system library such as using the #include directive. – Definition Section: All the symbolic constants are written in the definition section.
