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.
difference between constant and static variables in java
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.
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.
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).
The structure tag is a type. The structure variable is an instance of that type.

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.
a literal is a constant value, the difference is a variable can change it's value.
Whether or not you can change its value.
When referring to statistics, variable means that numbers change and can go up and down. If something is constant, numbers remain unchanged.
In a controlled experiment, the control variable remains constant while the experimental variable changes with each trial of the experiment.
In a controlled experiment, the control variable remains constant while the experimental variable changes with each trial of the experiment.
In a controlled experiment, the control variable remains constant while the experimental variable changes with each trial of the experiment.
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.
A parameter is a variable which takes different values and, as it does, it affects the values of some other variable or variables.
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.
Constant speed refers to a consistent rate of motion without fluctuations, while variable speed involves changing rates of motion over time. In constant speed, the object moves at a steady pace throughout, whereas in variable speed, the object may accelerate or decelerate at different points.
