Arrays: Lists and Tables Although the value of a variable may change during execution of a program‚ in all our programs so far‚ a single value has been associated with each variable name at any given time. In this chapter‚ we will discuss the concept of an array—a collection of variables of the same type and referenced by the same name. We will discuss one-dimensional arrays (lists) at length and focus briefly on twodimensional arrays (tables). You will learn how to set up and use arrays to accomplish

statements that we learn in Week 1:DeclareYou use Declare to tell the computer the names of variables and the types of variables. The syntax is:Declare variablename as type A variable name must begin with a letter‚ can include letters‚ numbers and the underscore. Spaces are not allowed. The variable type is based on the data that the variable will hold. For example‚ if the variable stores a name‚ then your variable is a string. If you are using currency values with dollars and cents‚ then you need

Constants : A symbol having a fixed numerical value is called a constant. Example : 7‚ 3‚ -2‚ 3/7‚ etc. are all constants. Variables : A symbol which may be assigned different numerical values is known as variable. Example : C - circumference of circle r - radius of circle Where 2 & are constants. while C and r are variable Algebraic expressions : A combination of constants and variables. Connected by some or all of the operations +‚ -‚ X and Example : is known as algebraic expression. etc. Terms :

is a local variable? What statements are able to access a local variable? A local variable is declared inside a module and cannot be accessed by statements that are outside the module. 5. In most languages‚ where does a local variable’s scope begin and end? Usually begins at the variables declaration and ends at the end of the module 6. What is the difference between passing an argument by value and passing it by reference? Passing an argument by value copies the data from the variable but does not

The independent variable is that “Data are available for 63 countries‚ with a total sample of 420‚599 individuals. Using a 3-level variance-known model‚ the authors found that individualism was a consistently better predictor than wealth‚ after controlling for measurement‚ sample‚ and temporal variations.” The dependent variables are that individualism is consistently associated with more well-being
