What are the data types of variables in foxpro?
In FoxPro, the main data types for variables include Numeric, Character, Date, and Logical. Numeric variables can store numbers, while Character variables hold strings of text. Date variables are used for storing date values, and Logical variables can represent true or false values. Additionally, FoxPro supports Memo fields for storing large text blocks and Array types for collections of variables.
Why structure variables cannot be compared?
They can be compared with memcmp, but you should be careful if your structures contain:- pointers- alignment gaps- numeric variables (byte order!)- nested structures/unions
What is the default initial value for all numeric types?
If they are instance variables the default initial value is 0. If they are method local variables, they are null and must be initialized to some value before they are used
What is an abstract equation?
An abstract equation is an equation where it is impossible, with the information given, to find the numeric values of the variables. For example 2X=4Y can be reduced to X=2Y or Y=X/2 or 2=X/Y but you cannot find the numeric values of X or Y.
How to check whether a character is numeric in an alphanumeric field in easytrieve.?

What is the definition of numeric constant?
Numeric constants have the capacity to store numeric value.
What is the numeric factor of the variable or variables in a monomial?
the coefficient
What is a numeric variable in ms dos basic?
In MS-DOS BASIC, a numeric variable is a type of variable that is used to store numbers, which can be integers or floating-point values. These variables can be manipulated using arithmetic operations, allowing for calculations and numeric processing within the program. Numeric variables in BASIC are typically defined by names that start with a letter and can be followed by letters, numbers, or underscores. Examples include variables like A, X1, and TotalAmount.
What is the definition of numeric constraint?
A numeric constraint deals with distances and size. Width, length, and depth are examples of these.

What is the definition of a computer program?
An organized list of instructions that, when executed, causes the computer to behave in a predetermined manner. Without programs, computers are useless.A program is like a recipe. It contains a list of ingredients (called variables) and a list of directions (called statements) that tell the computer what to do with the variables. The variables can represent numeric data, text, or graphical images.
What is a numerical number?
A redundancy. Numbers are numeric by definition.
Social security numbers numeric values therefore social security is an example of?
Since social security numbers have numeric values, a social security number is an example of a qualitative variable.
What data can be referred to things that can be counted?
A quantitative variable is numeric and therefore can be counted discretely or continuously. The other side of the spectrum is qualitative variables.
What is the difference between numeric and string variables?
Numeric variables store numbers for doing mathematics, counting etc.. String variables store printable sets of characters that can be read by humans in what ever language. int i=3; /* a numeric variable in c */ char *hello = "Hello world, Im 3 years old" /* string that contains a number */ Computer languages generally provide many different ways to transform one into the other.
What numbers variables?
In statistics and mathematics, numeric variables refer to types of data that represent measurable quantities and can be expressed as numbers. They can be classified into two main types: continuous variables, which can take on any value within a range (like height or weight), and discrete variables, which consist of distinct, separate values (like the number of students in a classroom). Numeric variables are essential for quantitative analysis, allowing for various statistical operations and calculations.
What is the meaning of qualitative variables?
Qualitative variables are variables that are used to categorize data based on characteristics or qualities, such as color, gender, or type of vehicle. They are non-numeric and are used to label or describe observations rather than measure them.
