A constant and variable are variations of data types.
int a;
is a variable and its value can be changed by the program as the program runs.
const int b;
is a constant with a fixed value and will have its value set and may not be changed by the program as as the program runs.
All data types may be declared as a constant.
Variable Value Can Be Changed By You In Programme.

∙ 11y agoA constant is a symbol that cannot be modified by the program while it is running, while a variable is a symbol that can be modified by the program while it is running. Constants are usually optimized as inline values, while variables will be stored on the stack or the heap.

Difference between variable and constant in terms of memory types?
constant means data item whose value cannot be altered or change. whereas variable is named storage location whose value can be manipulated during program run.
What is the difference between a constant and a variable in java programming language?
A constant in Java is defined using the "final" modifier. For instance: final double Density_Of_Water = 1.000; would set Density_Of_Water to 1.000. This value can not be modified throughout the program because "final" told the compiler that this value would not change. A variable however, can be changed by the user throughout the program.
What is constant explain their storage representation with suitable example?
A constant is a variable that is immutable. The storage representation is exactly the same as for any other variable of the same type, the only difference is that all constants are allocated in the program's data segment (static memory).
What is the difference between macros and constant variable?
Macros are processed at preprocessing time where as constant variables are processed at complie time. Macros doesnot have any scope but constant variables has scope. Macros doesnot have the type checking where as constant variables have type checking.

What the difference between a variable and control?
The difference between a controlled variable and a variable is in their state. A controlled variable is something which is rigid and constant while a variable is liable to change and inconsistent.
What is the difference between a variable and a literal in prgramming?
a literal is a constant value, the difference is a variable can change it's value.
What is difference between variable and constant?
Whether or not you can change its value.
Difference between variable and constant in statistics?
When referring to statistics, variable means that numbers change and can go up and down. If something is constant, numbers remain unchanged.
What is the difference between an experimentation variable and a control variable?
In a controlled experiment, the control variable remains constant while the experimental variable changes with each trial of the experiment.
What is the difference between experimental variable and a control variable?
In a controlled experiment, the control variable remains constant while the experimental variable changes with each trial of the experiment.
What is the difference between an experimental variable and a control variable?
In a controlled experiment, the control variable remains constant while the experimental variable changes with each trial of the experiment.
What is the difference between independent variable and a constant variable?
A constant is something that will ALWAYS remain the same in your experiment. For instance, the materials you use and the unit of measurements you use are examples of constants. An independent variable changes with the experiments.
What is difference between parameter and arbitrary constant?
A parameter is a variable which takes different values and, as it does, it affects the values of some other variable or variables.
What is the difference between permanent gases and variable gases in the atmosphere?
The difference between permanent and variable gases is that variable gases change in response to activities in the environment, and permanent gases stay constant.
What is the difference between a coefficient and variable?
A variable is a part of a term which can change. A coefficient is a numerical constant, associated with a variable. For example, in the term 3x^2 , 3 is the coefficient, while x is a variable.
