_______ are the best visual aids for showing the relationship between ideas in a presentation.
Answer:
A graphic organizers
Explanation:
Graphic users are the best visual aids for showing the relationship between ideas in a presentation.
What are Graphic user?
By the use of menus, icons, and other visual cues or representations, a user interacts with electronic devices like computers and smartphones using a graphical user interface (GUI) (graphics).
Unlike text-based interfaces, where data and commands are purely in text, GUIs graphically show information and related user controls. A pointing device, such as a mouse, trackball, stylus, or a finger on a touch screen, is used to manipulate GUI representations.
The first keyboard input and prompt system was used for the human-computer text interaction (or DOS prompt). At the DOS prompt, commands were entered to request responses from a computer.
Therefore, Graphic users are the best visual aids for showing the relationship between ideas in a presentation.

You are given two sorted arrays, A and B, and A has a large enough buffer at the end to hold B. Write a method to merge B into A in sorted order without using any other array space.Implementation instruction:1) Define one array of size 18 for A and the other array of size 5 for B.2) Initialize A by inputting 13 integers in the ascending order, and Initialize B by inputting 5 integers in the ascending order.
Answer:
#include <iostream>
using namespace std;
int main(){
int arrayA[18] = {1,2,3,4,5,6,7,8,9,10,11,12,13};
int n = arrayA.length();
int arrayB[5] = {14,15,16,17,18};
for (int i = 0; i < arrayB.length(); i++){
arrayA[n] = array[i];
n++;
}
}
Explanation:
The C++ program defines two arrays namely; "arrayA" and "arrayB". The first array has a space size of 18 while the second array has a size of 5. In the program, the second array is merged into the first array
Fill in the blanks, so the print statement displays the result of the function call in order.

9 Run # 1) Fill in the blanks so the print statement displays the result # of the function call
10 ---, --- = order_numbers(100, 99) print(smaller, bigger)
Answer:
Rep;ace the blank with
smaller, bigger
So, the complete line is:
smaller,bigger=order_numbers(100,99)
Explanation:
From the question, we understand that the program is to return the order of a number from least to highest
This has been well implemented in order_numbers function
Because the order function returns two values, the order_function must be called in order to accept two values and the syntax is:
value1,value2 = function(return-value1,return-value2)
In this case, the statement is:
smaller,bigger=order_numbers(100,99)
So, in the next line of the main, the values of smaller and bigger are printed:
print(smaller,bigger)

Write a function solution that, given an array A consisting of N integers, returns the number of fragements of A whose sum equals 0 (that is, pairs (p,q) such that P
Answer:
#include <iostream>
using namespace std;
void fragment(int arr[], int n){
for (int i = 0; i < n; i++){
for (int x = 0; x < n; x++){
if (x != i && arr[i] + arr[x] == 0){
cout<< arr[i] << " , " << arr[x];
}
}
}
}
int main(){
int n = 7;
int myArr = {1, 2, -1, -2, 0, 0, 3};
fragment(myArr, n);
}
Explanation:
The C++ source code defines an array called "myArr" in the main program and its array size n. The void function "fragment" prints out the pairs of the array whose sum equates to zero.
1. Write a function called changeLetter that can directly alter the value of a character variable. It takes one argument: a reference to a character. It returns nothing. If the passed in character is alphabetic ('a' to 'z' or 'A' to 'Z'), then make the character become the next higher ASCII value ('a' becomes 'b' etc.). If the passed in character is not a letter, don't alter it.
2. Write a calling statement for the changeLetter function. It takes one argument: a reference to a character and returns nothing. The calling statement should pass the char variable ch so that it is (potentially) altered.
3. Write a calling statement for the changeLetter function. It takes one argument: a reference to a character and returns nothing. The calling statement should pass the 2nd character in a char array called chAr (by second, I mean the sub-oneth) so that it is (potentially) altered.
4. Assume the following function header:
void fn( int &n )
Write an instruction for the function body that will store 10 into the caller's variable referred to by n.
5. Write a calling statement for the fn function. It takes one argument: a reference to an integer and returns nothing. The calling should pass the integer variable num to the function so that it can be altered.
6. The strlen() function returns
A. the number of chars in an array of char, including the null
B. the number of chars in an array of char not including the null
C. the declared number of chars an array can hold
7. What must be true of the arguments to strcat(s1, s2); More than one answer may be correct
A. s1 must be valid strings
B. s2 must be a valid string
C. s1 must have room to contain the result
D. s2 must have room to contain the result
8. How is a structure different from an array?
9. Write a definition for a structure called Part that can hold a part name (an array of characters that can hold 24 characters plus a null terminator), a part weight (int), and a part price (float). Make up appropriate names.
10. Assume the following structure definition:
struct Person
{
char name[50];
int age;
};
Write a declaration for a variable of type Person and initialize it with your name and the age 10. This should be done as part of the variable declaration statement.
11. Assume the following structure definition:
struct Person
{
char name[50];
int age;
};
Write a declaration for a variable of type Person and initialize it with your name and the age 10. This should be done as several executable statements.
12. Declare an array of 10 Person structures named peopleArray.
13. Assume the following structure definition and declaration:
struct Person
{
char name[50];
int age;
};
Person people[265];
Assuming that the people array contains 265 valid structs, write code to print out the age member for each item in the structure.
Answer:
1. Void changeLetter( char &ref )
{
If( isalpha(ref) )
{
Ref++;
}
}
2. changeLetter( ch );
3. changeLetter( chAr[1] );
4. n = 10;
5. fn( num );
6. (B) the number of chars in an array of char not including the null.
Explanation:
Functions are blocks of codes in any programming language. In C++, a void function is a function that does not return a value, while other types of functions have a return statement. There are three ways to pass an argument to a function in C++, by value, by reference and by pointer.
When a variable argument is passed as a value to a function, the value of that variable cannot be altered by the function, but when it is passed as a reference or a pointer, it can be altered.
To call a function in C++, specific the function name and the opening and closing parenthesis with the required arguments in between. The call must end with a semi-colon.

The method definition, or declaration, is defined as the method __________ followed by the method ________.
a. name, parameters
b. name, return
c. header, body
d. header, signature
e. signature, body
Answer:
The answer is option C "header, body"
Explanation:
Like a class, a method definition has two significant parts: the method revelation and the method body. The method declaration characterizes all the method's attributes, for example, access level, return type, name, and contentions. The method body is the place where all the activity happens. It contains the guidelines that actualize the method.
The lone required element of a method declaration are the method's name, return type, and a couple of brackets: ( and ). A method declaration can give more data about the method, including the return type of the method, the number and sort of the contentions needed by the method, and which different classes and objects can call the method.
In spite of the fact that a method name can be any legitimate identifier, code shows limit method names. By and large, method names should be action words (verbs) and should be in upper case, with the principal letter in lowercase and the primary letter of each inside word in capitalized.
