Using Struct

1. Program Sample Run 1

For first point:

Enter the value of x coordinate: 0

Enter the value of y coordinate: 3

For second point:

Enter the value of x coordinate: 4

Enter the value of y coordinate: 0

The distance between two given points is 5.

2. Program Sample Run 2

For first point:

Enter the value of x coordinate: -2.1

Enter the value of y coordinate: 3

For second point:

Enter the value of x coordinate: -9.12

Enter the value of y coordinate: 5

Write a function named SameNumberOfFactors that takes two positive integer arguments and returns 1 if they have the same number of factors and 0 if they have not the same number of factors.

Create a C++ program that reads 5 items and their prices and quantities. The program's basic requirements are as follows.

1.Declare four arrays of five elements each: item, price, quantity, and amount.

2. Declare the functions computeAmount, computeTotalAmount, displayItems, and strNew.

3.The expected output is depicted in the figure below.

strNew code:

//function that will adjust the string into specified length by adding spaces
string strNew(string str, int n) {
	int l;
	l = n - str.length();
	for (int i = 1; i <= l; i++) {
		str = str + " ";
	}
	return str;
}//end of strNew function

Output Example

Enter Item 1: Milk

Enter the price: 125.75

Enter the quantity: 3

Enter Item 2:

Enter Item 3:

Enter Item 4:

Enter Item 5:

Amount: 377.25

Total Amount: 377.25

=========================

Item Qty Price Amount

Milk 3 125.75 377.25

Cake 2 500 1000

Spaghetti 1 700 700

Fruits 10 50 500

Waffle 7 45 315

When will the ‘while’ loop be preferred over the for loop? Mention the scenario and write the

programme to demonstrate this?

Write an algorithm that displays an equivalent color once an input letter matches its first character.

For example b for Blue, r for Red, and so on. Here are the given criteria: (The letters as an input data and the color as output information).

Letters Color

‘B’ or ‘b’ Blue

‘R’ or ‘r’ Red

‘G’ or ‘g’ Green

‘Y’ or ‘y’ Yellow

Other letters “Unknown Color”

write a menu-driven program that asks the user to select a favorite color from the given colors. Keep asking the user three times for selecting the color from the list of the available colors. Do this with the help of a suitable loop and switch statement. Finally, you have to display the three favorite colors of the user.
