How do you identify variables in a research topic?
To identify dependent research variables, look for items in your research question or hypothesis that show the result, effect or outcome of changing the independent variable.The basic rule is to look for what causes reactions.
How do you write a variable in research?
The variables should be explained in more detail in the methods section of your paper.As with any academic writing, clarity and being succinct is most important, there are no rules about the structure and style for writing about independent or dependent variables.

How many data types are there in C?
There are five data types that are primary, but various derived data types are also present in C language that help in storing complex types of data.The derived data types are basically primary data types, but they are a bit more grouped together or twisted, such as a structure, array, pointers, union, etc.
