The selective structure that uses constants to check specific values is known as a "switch statement" or "switch-case structure." It allows a variable to be tested for equality against a list of constants, each associated with a block of code that executes if that constant matches the variable's value. This structure is often used for cleaner and more organized code when there are multiple potential values for a variable that need to be handled distinctly.

What is the definition of symbolic constants in c language?
constants are values that does not chnage through out the program exceution..
How do you uses enums?
Enums are constant values. You use them when you want to limit the range of acceptable constants.
What is a declared constant?
A declared constant is a variable whose value is set at the time of declaration and cannot be changed throughout the program. In many programming languages, constants are defined using specific keywords, such as const in JavaScript or final in Java. This ensures that the constant maintains its assigned value, providing clarity and preventing accidental modifications. Constants are often used to represent fixed values, such as mathematical constants or configuration settings.
How is a structure initialized?
In C, structures are uninitialized by default. To initialize a structure you will typically zero the memory allocated to the structure and then set specific members to specific values. If all members are non-zero, you can simply set those members rather than zero the memory first. In C++, structures are initialized via inline initializes and/or through the class constructor.
What is mean map in java?
In Java, a mean map typically refers to a data structure that combines a map (or dictionary) with a statistical function to compute the mean of values associated with specific keys. The Map<K, List<V>> structure can be used to store multiple values for each key, allowing for easy calculation of the mean by averaging the values in the list for each key. This approach is helpful in scenarios where you need to aggregate and analyze data efficiently. By iterating through the map, you can compute the mean for each key's associated values as needed.
How many constants are there?
The concept of "constants" can vary depending on the context. In mathematics, constants are fixed values that do not change, such as π (pi) or e (Euler's number). In programming, constants refer to values that cannot be altered during the execution of a program. Thus, the number of constants can be infinite in mathematics, while in specific applications like programming, it is limited to those defined within that context.
Where are the constants located in math?
In mathematics, constants are fixed values that do not change. They can be located in various places, depending on the specific context. For example, in algebraic equations, constants are typically represented by specific letters or symbols and are found alongside variables. In geometric formulas, constants may be included as part of the formula itself. Constants can also be defined and used in mathematical functions, formulas, or mathematical theories.

What are cosmic numbers?
Cosmic numbers are rare mathematical constants that appear to be related to fundamental physical constants in the universe. They are believed to have important connections to the structure and behavior of the cosmos, although their significance is still not fully understood. Examples include values like the fine structure constant and the proton-to-electron mass ratio.
What is the use of constants and variables in programs?
to store values
Why do constant constants have units?
Constants in the sense you mean are different to mathematical constants. They usually refer to a system in which two values are proportionate and so are of the units associated with the system.
What Are facts about Constant?
Constant is a mathematical term that refers to a fixed value that does not change. In algebraic equations, constants are letters or symbols that represent specific numerical values. Constants can be added, subtracted, multiplied or divided in equations to generate different results.
What is the answer in algebraic expression consists of two terms?
values and constants
What are the values that are used in a function?
There are several possibilities. They can be called arguments and there are two kinds, variables and constants. Variables can have different values and constants are always the same.
What is made up of quantities and the operations performed on them does not contain?
In mathematics, a structure that is made up of quantities and the operations performed on them but does not contain specific numerical values is called an algebraic expression. This structure includes variables, constants, and operators, allowing for the representation of a wide range of mathematical relationships without specifying exact numbers. Algebraic expressions can be manipulated and simplified but do not yield a definitive result until values are assigned to the variables.
What is literal constants and symbolic constants?
Literal constants are fixed values that do not change during the execution of a program, such as numbers (e.g., 5, 3.14) or strings (e.g., "Hello"). Symbolic constants, on the other hand, are named identifiers that represent a value, which can improve code readability and maintainability; for example, using PI to represent the value of 3.14. While literal constants are directly written in the code, symbolic constants are defined using keywords or specific syntax in programming languages, often in uppercase to distinguish them.
What is A and B in redwood viscometer?
In a redwood viscometer, A and B are constants used in the formula to calculate the viscosity of the fluid being tested. The formula is viscosity = A + B * time in seconds. The values of A and B are specific to the design of the redwood viscometer and are typically provided by the manufacturer.
