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.?
IF WS-AGE NUMERIC DISPLAY "NUMERIC" ELSE DISPLAY "NOT NUMERIC' END-IF
What are the rules for the expression evaluation in Java?
* arithmetic expressions are evaluated from left to right using the rules of precedence.. * when parentheses are used,the expressions within parentheses assume highest priority... * if parentheses are nested, the evaluation begins with the inner most parentheses... * the associativity rules are applied when 2 or more operators of same precedence level appear in a sub expression
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 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?

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.
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 scientific definition of a control variable?

What do you call variables in a experiment that you can change?
