- Differentiate between constants and variable
Constants
variables
characteristics
Value is not changeableduring the course of the program
Value can be changedanytime during the course of the program
usage
Use constant when you want to declare something that won't change midway in your program execution.
Use variable to store data thatmay or will change during the running of the program.

What are all the variables?
There are 'constant variables' , 'independant variables' and 'dependent variables' Constant Variable- things in the experimment that should be kept the same Independant variables- something that can be varied in an experiment Dependant variable- something that can be affected
What variables in turbo C?
There are mainly 3 types of variables in c. Integer, Float and character :)
Are C variables initialized to 0 by default?
Only global/static variables are, local variables aren't.
What is literal in c language?
a string constant
What is constant variables?
Variables are items, which change their values during the execution of a program. Constants do not change the value during the execution of a program.
Differentiate between C Constants and C variables?
A constant value cannot be changed once set. A variable can be changed whenever you want.
What does constant of proportion mean?
If two variables are in direct relationship then the ratio of the two variables is known as the constant of proportion between them. In algebraic form, if X and Y are the two variables, then direct proportionality implies that Y = cX and c is the constant of proportionality.
Are constant variables and derived variables the same?
Constant variables are constant, they do not change. Derived variables are not constant. They are determined by the other values in the equation.
What is constant variable in c?
Constant variables refers to those variables whose values cannot be changed. These variables should be initialized along with their declaration. Attempt to change the value of a constant variable will generate compile error. The syntax for declaring a constant variable is:const data-type variableName = value;
What is the constant of proportionality in math?
If two variables, X and Y, are in direct proportion then Y = c*X for some fixed value c. This value, c, is the constant of proportionality for this relationship.
What is the definition constant of proportionality?
The state of being in proportion.
What are the characteristics of inverse proportionality relationship?
If the product of two variables is equal to a constant, then they are inversely proportional. eg. If xy=c where c is a constant, then x and y are inversely proportional.
Differentiate the three types of variable?
differentiate the three types of variables from one another
Are constant variables and independent variables the same?
No they are not the same. A constant variable keeps going at a constant rate.
What is a constant variables in c language?
It are a variable you add modifer 'const' to. It means these variable mustn't be modified.
What is the direct proportion?
Two variables, X and Y, are said to be in direct proportion if X/Y is a constant. Equivalently, Y = cX for some constant c.
What is the general form of a direct-variation equation?
y = cx where x and y are the two variables and c is a constant.
