3. Are Strings Created Equally?

by CodeChum Admin

Do you believe in doppelgangers? Well they are very much possible with strings! Check if the two given strings are the same or not.

Instructions:

1. Input two strings in different lines (one each line).
2. Print out the strings in one line, separate them with a \.
3. Check whether the two strings are equal, print out "Equal" if they are.

Instructions

1. Input two strings in different lines (one each line).
2. Print out the strings in one line, separate them with a \.
3. Check whether the two strings are equal, print out "Equal" if they are.

Input

Two lines containing a string on each.

hello
hello

Output

The first line contains the two inputted strings separated by a \.

The second line contains a string result.

hello\hello
Equal

They say that the one in first place is always greater than the one in the second and third place. Are they always right?

Instructions:

1. Input three integers in different lines (one each line).
2. Print out the integers in one line.
3. If the 1st integer is greater than or equal to both the 2nd integer and the 3rd integer, print "Yes".

Instructions

1. Input three integers in different lines (one each line).
2. Print out the integers in one line.
3. If the 1st integer is greater than or equal to both the 2nd integer and the 3rd integer, print "Yes".

Input

Three lines containing an integer on each.

3
2
1

Output

The first line contains all the three inputted integers.

The second line contains a string which is the result.

Write a C++ program which accepts amount in rupees as input (integer) within Range from

Rs. 100 to Rs. 100000 and then asks the user for particular currency note preference and display the total

number of currency notes of Rs. 500, 100, 50, 20, 10, 5, and 1. The user can be given a maximum of 200

notes of his preferred choice. (5 marks)

For example: when a user enters a number, Rs. 57477 and enters 50 notes as his preferred choice, the

results would be like this.

Currency Note : Number

500 : 94

100 : 4

50 : 200

20 : 3

10 : 1

5 : 1

1 : 2

Using switch-case statements only, write a C++ program that displays the following menu for

the food items available to take orders from the customer: (10 marks)

● Burgers

● Pizzas

● Sandwiches

When the user selects one of the options, a further submenu is displayed according to the chosen option.

The online food shop offers Crispy Chicken Burger (600 Rs.), Beef Burger (650 Rs.), and Fish Burger (700

Rs.) in the Burger category; Chicken tikka, Chicken Fajita and Four Seasons in the Pizza category; whereas

Club (300 Rs.), Chicken (325 Rs.), and Vegetables (315 Rs.) in the Sandwiches category. Prices of each food

item is also displayed to the user in the selected sub menu. The user will select the food item and quantity

of the item. In case of the Pizza items, the user can also select the size of pizzas (i.e. Small (850 Rs.),Medium (1200 Rs.), and Large (1600 Rs.)). The program outputs the total charges according to the chosen

options.

IFone, a cellular company, offersthe following three postpaid data packages to its customers.

(5+5 marks)

● Package A: For Rs. 100 per month, 1 GB data is provided. Additional data can be purchased for

Rs. 20 per 100 MB.

● Package B: For Rs. 200 per month, 2.5 GB data is provided. Additional data can be purchased

for Rs. 10 per 100 MB.

● Package C: For Rs. 1000 per month, unlimited access is provided.

Part A: Write a program that calculates a customer’s monthly bill. It should ask how many GBs the

customer has used in the month and which package the customer has subscribed for. It should then

display the total amount due.

Part-B: Modify the program in Part A so that it also displays how much money Package A customers

would save if they purchased packages B or C, and how much money Package B customers would save if

they purchased Package A or C. If there are no savings for a particular package, your program shall print

an appropriate message.

You are given a 9*9 grid as shown in the figure below. You can determine the color

of each square from the grid. The number of each square is also shown below. Write a C++ program for

this below given grid. The user is given two options to select from.

Part A: When the user selects 1st option, the user will enter number of square in this grid (any

number from 1-81). Your program will determine the color of the square.

Part B: When the user enters 2nd option, the user will enter two numbers from this grid. Your

program will determine if the two squares entered in this 9*9 grid have same color or not.
