Constant is the speed of light and as the speed of light cannot change it is 'constant'
to store values
so scientist can compare result
There are 4 constants.
Variables change, constants do not.
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.
Integer constants Character constants Real/floating point constants String constants
Coding constants in c means writing the constants in a certain way that the c language understands.
By using algebra. You have to isolate the variable and use the constants to find the varaible.
Enums are constant values. You use them when you want to limit the range of acceptable constants.
It's arbitrary. That's the way that constants are defined.
To determine the activation energy of a chemical reaction using two rate constants, you can use the Arrhenius equation. By plotting the natural logarithm of the rate constants against the reciprocal of the temperature, the activation energy can be calculated from the slope of the resulting line.
The Universal Economic Constants are Production, Investment, Savings and Consumption.
