How do I fix undefined error in C++?

You need to pass the values to the function Calculate. Variables x, y, z and function are not accessible outside the class and also u need a return type to the function so that you can get the output from the function Calculate.

What does undefined symbol mean?

UNDEFINED SYMBOL AT COMPILE TIME An undefined symbol at compile time indicates that the named identifier was used in the named source file, but had no definition in the source file. This is usually caused by a misspelled identifier name, or missing declaration of the identifier used.

How do you write undefined?

If f is a partial function on S and a is an element of S, then this is written as f(a)↓ and is read as “f(a) is defined.” If a is not in the domain of f, then this is written as f(a)↑ and is read as “f(a) is undefined”.

How do you write undefined in math?

The expression 00 is undefined in arithmetic, as explained in division by zero (the same expression is used in calculus to represent an indeterminate form). Mathematicians have different opinions as to whether 00 should be defined to equal 1, or be left undefined.

What is undefined reference in C?

How do you find undefined?

We learned that a numerical expression is undefined when there is no answer or when you get division by zero. We might get division by zero for those numerical expressions with variables and a denominator. To find the points where the numerical expression is undefined, we set the denominator equal to zero and solve.

What is undefined in geometry?

We’ve learned that in geometry, there are four undefined terms. Undefined terms are those terms that don’t require a formal definition. The four terms are point, line, plane, and set. A point is quite simply, a dot. Points are labeled with one capital letter.
