You declare a variable when you create it by specifying its datatype and name in a programming language. This tells the compiler or interpreter to allocate memory for the variable. Variables must be declared before they can be used in most programming languages.

The variable that is measured in an experiment is the variable?

The Independent/Manipulative variable is the variable that you purposely change, and the Dependent/Responsive variable is the variable that changes as a rest of the Independent variable. You measure the dependent variable to see the effects of the Independent variable.


What is the variable that causes a change in another variable?

An independent variable is the variable that causes a change in another variable, known as the dependent variable. The independent variable is manipulated or controlled in an experiment to observe its effect on the dependent variable.


What is the name of the variable that's used to predict another variable?

The variable that is used to predict another variable is usually called the "independent variable" or the "predictor variable." This variable is manipulated or controlled in an experiment to observe its effect on the outcome variable, which is known as the "dependent variable."


What is a variable called that causes a change in another variable?

A variable that causes a change in another variable is called an independent variable. This variable is manipulated or controlled by the researcher to observe its effect on the dependent variable.


What variable causes an effect?

The independent variable is the variable that is changed or manipulated by the researcher and is hypothesized to cause an effect on the dependent variable. The dependent variable is the variable that is measured in response to the changes in the independent variable.

Why all variables are declared with in the function?

It is not necessary to to declare variables inside the function in C. If you declare a variable inside a function, the variable becomes local for the function and another variable of same name can be declared in any other function, but you can not use the variable declared in other function. When you declare any variable outside the function body then the variable becomes global and can be used in any function of the program. Note: errno is an example for a variable declared outside any function.

How do you declare variables and constants.explain with example?

Depends on the programming language you are using. I will give two simple examples. In Command Prompt and when creating a batch file, you declare a variable by entering the "set" command. You can use different switches to change the type of variable you are declaring. /p makes the variable able to accept user input. /a makes the variable a numerical expression. In Python, you declare a variable just by stating the name of the variable and its value. x = value.
