Write a C++ program to find the table of numbers using a while loop. Your program should ask the size of the table. That size defines the rows and columns.

Explain how overloading a unary operator is almost similar to overloading a binary operator with necessary examples and include main() function to demonstrate. Mention the differences between these two in terms of number of operands they deal with.

A customer opens an account at a bank with an initial amount. The account number, name, and balance of the customer are generated. The customer can deposit money and withdraw money as per need, this will modify the existing account balance. It should also be checked if the demanded amount is available during withdrawal. The customer can also close the account, the available amount will be paid out. Write a programme to input and display data for 5 customers with the use of Constructor and Destructor

Make a file by yourself named ”Integer.txt” and add 5 integer values in it. Now, write a C++ program that reads data (5 integers) from the file and store them in integer array. Also make another integer array (int result []) of same size to store the results. The program should check for each number in array if it is prime number or not. If the number is prime, update value in result[] array from 0 to 1. Lastly, write output in another file named “Result.txt” 

The Positive Ones

by CodeChum Admin

There are different kinds of numbers, but among them all, the most commonly used numbers in our daily lives are those positive ones. So, I only want you to count all the positive numbers from the 4 outputted values and print out the result.

Go and search for the positive ones among these four!

Define a function CalcPyramidVolume with double data type parameters baseLength, baseWidth, and pyramidHeight, that returns as a double the volume of a pyramid with a rectangular base. Relevant geometry equations: 

Volume = base area x height x 1/3 

Base area = base length x base width. 

(Watch out for integer division).

Where's the Biggest One?

by CodeChum Admin

We've already tried comparing 3 numbers to see the largest among all, so let's try a more complicated mission where we locate the position of the largest among 5 numbers. There are only 4 possible cases for this mission:

- if the largest digit is the first digit, print "Leftmost"

- if the largest digit is the third digit, print "Middle"

- if the largest digit is the last digit, print "Rightmost"

- if none of the above is correct, print "Unknown"

Now, show me how far you've understood your lessons!

Make a file by yourself named ”Integer.txt” and add 5 integer values in it. Now, write a C++

program that reads data (5 integers) from the file and store them in integer array. Also make another

integer array (int result []) of same size to store the results. The program should check for each number

in array if it is prime number or not. If the number is prime, update value in result[] array from 0 to 1.

Lastly, write output in another file named “Result.txt”

Example

Input:

Integer.txt

2 11 1 17 8

Output:

Result.txt

1 1 0 1 0

Hint: Prime number are those which is only divisible by 1 or itself.
