In computer programming, a number without a variable is referred to as a "magic number," because it seems to appear out of nowhere (like magic!). This is typically considered a bad thing, as that number will have no implicit meaning.
{
diameter = 10;
area = 3.14 * diameter; // here 3.14 is a magic number
}
{
pi = 3.14
diameter = 10;
area = pi * diameter; // now the meaning of this statement is unambiguous
}

What is the Algorithm for exchanging values of two variables?
There are three primary algorithms to exchange the values of two variables. Exchange with Temporary Variable temp = a; a = b; b = temp; Exchange Without Temporary Variable Using Exclusive Or a = a ^ b; b = b ^ a; a = a ^ b; Exchange Without Temporary Variable Using Arithmetic a = a + b; b = b - a; a = a - b;
What is Variable Turbine Technology?
various number of spools
Which of the following is not a variable data type real integer number or string?
FILE, struct stat and struct tm are some examples.
Why static variables in a function have global extent?
A variable declared static outside of a function has a scope the of the source file only. It is not a global variable. A variable declared outside of a function and without the static qualifier would be a global variable.
What is the independent variable of a variable?
Just the number, for example: 7x the variable is 7. The variable is the number without the variable(x,y,z, etc.)
A single number without a variable?

What is a number without a variable in a equation?

How do you represent a monomial with a degree of 0?
That would be a pure number, without a variable.
What is the degree for a number without a variable?
anything without a variable is to the first power. To find the degree, you look at what the power of the number is and that will be the degree. The degree is the number of times your coefficient is a factor. Since the exponent is one, so is the degree. Ex. 2x squared = 2nd degree
Can you multiply a number with a variable and a number without one?
yes you can so like 3x*5 would =15x
What is the definition of constant used in math?
A number without a variable. Ex.) 5 is a constant, 5x is not.
What is a variable minus a number and variable?
