12C
If we're talking strictly algebra. 12 equals p of c can be written as: 12= p(c) meaning, 12 is the answer for some function p, when c is the variable.
I can tell you that it is not an illegal variable name in C. I do not currently have a C++ compiler installed, but I would assume that it would also be valid in C++.
The variable c times the variable b simply equals cb. Just as the variable x times the variable y would equal xy, and so on.
An example of a quadratic equation is ( ax2 bx c 0 ), where ( a ), ( b ), and ( c ) are constants and ( x ) is the variable.
Assuming that x and y are two variables, such as they might be in Algebra, and that the expression "xy" is meant to be the multiplication of x times y, you would write it as x * y This expression could be used with a third variable in an assignment statement, or as a condition in an if statement where it can be compared to another variable or a constant.
In C++, enum signifies a slightly stronger type than in C. For example, in C, one could write: enum Direction { UP, DOWN }; Direction d = 1; In C++, this would be illegal, only UP or DOWN can be assigned to a variable of type Direction, though there is still implicit casting to integer, so one could still write: int i = UP; Another difference has to do with the way variable are declared in general in C++. In C, once the enum was declared as above, declaring variables of type Direction would have to be done through the enum keyword, like this: enum Direction d = UP; In C++, the name "Direction" becomes a type in itself, so you can write: Direction d = UP;
12 degrees below zero is written as -12°C.
a) fixed variable b) variable resistance c) body weight resistance

A variable changes. It varies. A non variable does not change. It is constant. For example if I write a mathematical expression such as x + 1, then x is a variable. Its value can be whatever value we choose. However 1 is a non variable. Its value is 1 and never changes from 1. In a scientific experiment a variable would be something that you changed from one test to another. A non variable would be something that remained constant from test to test. As a final example: the speed at which light travels in a vaccum is a constant. It is referred to by the letter c which stands for the universal constant. However, the speed at which your car travels is a variable. It changes.
It would be 12 degrees Celsius.
