Test 2 Review Outline

Loops while syntax & style SVRL EOF characteristics loop control variable must change value pretest may not be executed when to use

Loops do … while syntax & style characteristics loop control variable must change value postest always executed at least once when to use

Loops for syntax & style three expressions (initialization, continue test, update) increment/decrement operators scope characteristics pretest

Loops Nested loops

Arrays Single Dimensional syntax & style size index range how stored in memory data types referencing single elements of the array initializing syntax & rules Parallel Concerns running off end comparing assigning one array to another outputting content

Arrays What kind of loop to use ‘for’ loop used when know how many elements to store or process usually ‘while’ is used if do not know loop should count the number of stored elements

Arrays Two-dimensional Arrays syntax & style how stored in memory C – Strings what it is (2-D array of char) how used to store strings referencing a single string in an array of C-strings

Functions Syntax & Style function definition where located in source code file header format return type parameter(s) array as a parameter using const local variables scope calling functions void functions functions with return types other than void boolean other function prototypes Passing information to functions Pass by value Pass by reference passing array elements passing arrays

More Functions Scope of a variable or function name Lifetime static local variables global variables where are their declaration(s) located problems associated with scope initialization of local variables with same name global named constants when to use

Functions and 2-D Arrays Specification of 2-D array as parameter in the prototype in the definition calling the function
