Initialization

conditions

body

What are the 4 components of a loop?

Accumulator

It is sum of the variables of the counter

For loop

It is a loop used to repeat a specific block of code a KNOWN number of times

while loop

It is a loop used to repeat a specific block of code an UNKNOWN number of times

do-while loop

A loops used when a block of code is needed o be executed at least once

False

True or false

\
In **for (initialization; condition; dec)** loop statement; the final value for the loop control variable should be greater than the initial value in order to execute the statements inside the for loop

True

True or False

\
In **for (Initialization; condition; inc)** loop statement; the initial value of the loop control varable should be less than the final value in order to execute the statements inside the for loop

Array

It is a collection of variable of the same type that are referenced by a common name.

Extraction

It is a function that accepts an array *a* and element of its index type *i* and returns an element of the array’s base type

\
ex: cout << a\[i\];

Storing

It accepts an array *a*, an element of its index type *i,* and an element of its base type x

\
ex: a\[1\]=4

300

How many elements can int name \[30\]\[10\] store?

rows

in int name \[30\]\[10\], what does 30 determine?

columns

in int name \[30\]\[10\], what does 10 determine?

True

True or false

\
The index for a 2D array should always be an int

False

True or false

\
It is possible to run a 2D array using variables instead of int constants

\
ex: int name \[a\]\[b\];

Functions

These are the building blocks in C language. It is a subroutine that containts one or more C statements that performs one or more tasks

Function definition

it is a set of instructions for perfoming a task

Local variable

* A variable defined within a function
* It cannot be recognized by other functions

Global variable

a variable declared outside of all functions and can be used in any part of the program

Formal Parameter

They are variables that are declared to ACCEPT the actual parameter values

Actual Parameter

They are values that are given or passed to the formal parameter
