There is no such thing as a constant variable. A value is either constant or it is variable, it cannot be both. To answer the question, a constant value cannot be changed anywhere in a C++ program. Only variable values can be changed.
In C++ all false relational expressions have a mathematical value of 0.
You can calculate a value if you assign a value to variable "x".
A variable is a place to store a value that may change while the a program runs.
It is impossible to give any decimal/numeric value if we are not given the values of at least one variable, so the answer is B + B + B + C + C + C.
If I understand the question correctly, and that is by no means certain, then x = (y-1)/2
Its type, its value and its memory address.
Without an equality sign the given expression can't be considered to be an equation and so therefore a solution is not possible.
There is no variable, and the equation is not valid.
A 'float' variable may contain decimal values other than integer, and may also be expressed as scientific notation. As a result, float variables can express very large or very small values (10^38, 10^-38).
In call by value, you can only pass values stored in variables and catch them in other variables, actual variables are mostly unaffected (value of only one variable can be modified in one call). In call by reference, you pass address of variables, so actual variables are modified (multiple values can be modified in one call).
This is an instruction to increment the value of a variable by 1 (in this case, either the variable count or the variable total).
To find the values of X and Y you need two independednt linear equations. There are no equations given, only an expression involving a third variable, i
Both ++you and you++ have the same ending result. The variable you is incremented. The difference is that, if you use the combination in a larger expression, then you++ will have the initial value of you, while ++you has the incremented value of you.
The numerical value will depend on the values of each variable. The expression can't be further simplified, except that the parentheses can be omitted.
A variable is any named value of a specified type that can hold any value of that type, and that can change that value at any time while the name is in scope. A constant is exactly the same as a variable except that its value must be set at the point of instantiation and the given value cannot be altered while the name remains in scope. In other words, a variable is a value that may vary while a constant is a value that always remains the same.
It is an expression in two variable: it is NOT an equation. There is no standard form for expressions.
It is a variable which can take any value.
And what is the question? - The value of such an expression will depend on the value assigned to the variable, in this case, "t".
Without an equality sign the given expressions are not equations and so finding the value of y is not possible
It is, in fact, an identity - which is an equation which is true for all values of the variable.
You declare a variable by first defining its data type and then its name followed by a semi-colon. Here is an example: int variable; The example above declares an uninitialized integer variable. You can initialize the variable by giving it a value such as "int variable = 1;". It is important to initialize your variables, because you can get errors when executing your program that the variable does not have a value or is uninitialized. Variables that are uninitialized have whatever garbage value happens to be when the program is executed. Here are all of the data types that a variable can be: *int - integer value *char - character value *bool - boolean value
In the expression 5 + y + 8, y is a variable. We know how much 5 and 8 are, those are definite quantities. Only y has an unknown, and hence variable value.
Instantiation is creating the instance of the variable/object . While Initialization is to provide the variable with some value. int i; // i is an instance of an integer i=10; //initialised with the value 10
