Instructions

• Indent your code properly & follow variable name giving conventions.
• There will be no makeup of this assignment.
• Use best coding practices.
• Cheating and sharing is strictly prohibited.
• Student Copying Assignment / Lab / Quiz will be grade 100% negative marks.
• Student Copying Assignment / Lab / Quiz, two or more times will be dropped from lab/course.
• No Excuse will be entertained when Submission timing is over.
• Submit is submission folder till 1:00 pm Thursday, September 11, 2014.
• Follow the submission details told in class.

Basic Practice Problems:

1. All examples and exercises from chapter 6 and 7.
2. Write a C++ program to reverse the element of an integer 1-D array.
3. Write a C++ program to swap first and last element, then second and second last element and so on of an integer 1-d user defined array.
4. Suppose A, B, C are arrays of integers of size M, N, and M + N respectively. The numbers in array A appear in ascending order while the numbers in array B appear in descending order. Write a program to produce third array C by merging arrays A and B in ascending order.
5. Write a function called zero_small() that has two integer arguments being passed by reference and sets the smaller of the two numbers to 0. Write the main program to access the function.
6. Given two arrays of integers A and B of sizes M and N respectively. Write a function named MIX () with four arguments, which will produce a third array named C. such that the following sequence is followed. 
   All even numbers of A from left to right are copied into C from left to right. 
   All odd numbers of A from left to right are copied into C from right to left. 
   All even numbers of B from left to right are copied into C from left to right. 
   All old numbers of B from left to right are copied into C from right to left.
   A, B and C are passed as arguments to MIX (). e.g., A is {3, 2, 1, 7, 6, 3} and B is {9, 3, 5, 6, 2, 8, 10} the resultant array C is {2, 6, 6, 2, 8, 10, 5, 3, 9, 3, 7, 1, 3}
7. Write a program that lets the user perform arithmetic operations on two numbers. Your program must be menu driven, allowing the user to select the operation (+, -, *, or /) and input the numbers. Furthermore, your program must consist of following functions:
   1. Function showChoice(): This function shows the options to the user and explains how to enter data.
   2. Function add: This function accepts two number as arguments and returns sum.
   3. Function subtract: This function accepts two number as arguments and returns their difference.
   4. Function multiply: This function accepts two number as arguments and returns product.
   5. Function divide: This function accepts two number as arguments and returns quotient.
8. You have to write a program in which you have to declare an array of SIZE , any constant value.

• Call a function initArray(int []) and pass the array in it. The function should initialize all the array elements to user given values. Function returns nothing.
• Now call another function doubleArray(int []) which receives same array as that of initialized array and returns the square of each element of the original array.

Example :

Arr [SIZE]={1,2,3,4,5,6,7,8,9,10};\\if SIZE was 10, input was like this

Returned array will have 1,4,9,16,25,36,49,64,81,100.

1. Write separate function to perform following tasks with in the program for character array. You can define constant size as 500. Take input in array and

1. Find the length of a user given array
2. Concatenating two user given character arrays
3. Replace a user given word (a character array) from a user given array.

1. Write a function convertbinary(int a) that takes one parameter and convert the received number in binary, and display the binary value. Test with main().

1. Do the task discussed in end of the class for row and column major traversal of 2d and 1d arrays.

Tasks to submit as an assignment

1. You have to write a function that takes 3 Parameters as their default values “4”. The function should return the L.C.M of all the arguments passed. You will call the function in main() like

LCM(3);        

LCM(4,4);

LCM(1,2,4);

LCM();

        Or it can be called after taking values from user to pass as parameters.

1. Paper, Scissor and Rock is a very famous game. Two players choose any of the given choice.

1. If Player 1 chooses “Paper”and Player 2 choses “Rock”. Player 1 wins (As paper covers Rock).
2. If Player 1 chooses “Paper”and Player 2 choses “Scissor”. Player 2 wins (As scissor cuts paper).
3. If Player 1 chooses “Rock”and Player 2 choses “Scissor”. Player 1 wins (As Rock can’t be cut by scissor).
4. If both player choose same choice. It’s a Draw.

Now you have to write a program that makes this game. In a way that in main () you will only call functions and nothing else. Functions are:

1. MENU()

• In this, you will show a user to select a choice that whether he/she wants to play with Human or Computer or wants to Exit.

1-Play with Human

2-Play with Computer

3-Exit Game

• The function will return a choice.
• On the Basis of the choice returned, call another function. playHuman(), playComputer() or exitGame().

1. playHuman()

• In this you will take inputs from Player 1 and Player 2. According to the choices made.  Decide who wins or lose or draw.
• After showing output. Ask the user again whether he wants to continue playing or not.
• If “Yes” play again. Otherwise “Exit”.

1. playComputer()

• In this you will take choice from Player and call a function (with in playComputer(), call a function computerChoice()) that will return the random choice of computer about Paper, Scissor or Rock. According to the choices made., decide who wins or lose or draw.
• After showing output. Ask the user again whether he wants to continue playing or not.
• If “Yes” play again. Otherwise “Exit”.

1. exitGame()

Exit will simply close the program.
