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.

How do you declare a constant using PHP?
Outside of a class definition, constants can be declared with the define function. The function has two arguments; the name of the constant (a string), and the value of the constant (any variable type).Inside a class definition, constants can be declared with the const keyword. Type the word const, the name of the constant in the form of how it will be called later, an "equals sign," then the desired value of the constant.In both cases, here is an example.
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.

Can you declare constructor as constant if yes why?
Constructors are implicitly constant members of a class. They do not modify objects, rather they initialize them. So constant and not constant objects can invoke them: const MyClass object; // invokes MyClass::MyClass() constructor
How would you declare a constant of 5 called MYCONST?
A constant of 5 called MYCONST would be declared as #define MYCONST 5. This is because the statement used is a define statement.

What is a symbolic constant in c language?
symbolic constants are constants represented by symbols.... constants are values that does not change through out the program execution. e.g #include<stdio.h> #include<conio.h> #define NUM 15 void main() { int a=NUM; printf("The constant is %d",a); getch(); } here #define is a preprocessor. its job is to replace all the entries named NUM as 15. So that the compiler works with the constant 15...
