12c
To express 136 divided by ( c ), you would write it as ( \frac{136}{c} ). This notation indicates that 136 is being divided by the variable ( c ). Alternatively, you could also write it as ( 136 \div c ).

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.
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.
An example of a quadratic equation is ( ax2 bx c 0 ), where ( a ), ( b ), and ( c ) are constants and ( x ) is the variable.
In C, you can write 2n by using the multiplication operator. If n is a variable of an integer type, you would write it as 2 * n. For example, if n is defined as an integer, you can define it as follows: int n = 5; // or any integer value int result = 2 * n; // result will be 10 if n is 5
To write the sum of 9 and ( c ) in an algebraic expression, you simply combine the two terms using the addition symbol. The expression is written as ( 9 + c ). This indicates that 9 is being added to the variable ( c ).
In the context of C programming, 12 n typically refers to declaring a variable named n and initializing it with the value 12. The correct syntax for this would be int n = 12; where int specifies that n is an integer type. If you meant something else by "12 n," please clarify for more specific information.
To write an algebraic expression for the phrase "the product of 15 and c," you multiply the two quantities together. The expression can be written as ( 15c ). This indicates that you are taking 15 and multiplying it by the variable ( c ).
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;
