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
}
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;
Optional is the assignment of the value of course.int number; //Variable Declarationint number=2; //Assignment Declaration
various number of spools
FILE, struct stat and struct tm are some examples.
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.
Just the number, for example: 7x the variable is 7. The variable is the number without the variable(x,y,z, etc.)
Magic number
a constant
A constant.
Constant? not positive
That would be a pure 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
yes you can so like 3x*5 would =15x
A number without a variable. Ex.) 5 is a constant, 5x is not.
a variable minus a number and the same variable is b-6b= -5b
the number next to a variable that multiplies the variable
You have not told us what expression you wish to simplify.
