C

Implement the function Append (char** s1, char** s2) that appends the second character array to the first, replaces the first array with the result and replaces the second character array with the original first array. For example, if the first character array is "hello" and the second is "world" at the end of the function the new value of the first character array should be"helloworld" and the second array should be "hello". If the input is invalid the function should return 1. Otherwise, the function should return 0.

Input is double pointer (**). No use of <string.h>, USE malloc

#include <stdlib.h>

#include <stdio.h>

int

Append(char **s1, char **s2){

//implement

}

int main(){

char myArray1[7] = "hello";

char myArray2[10] = "world";

char *myArray3 = myArray1;

char *myArray4 = myArray2;

Append(&myArray3, &myArray4);

return 0;

}

Create a loop which gives the player instructions on what to input. Then read input from the player. The input will be either one of three options:

• If the user enters the word “answer” or some other string you choose to indicate the player is ready to end the game and guess. In this case, output the hidden rule.

• Three numbers separated by spaces. Let’s call a trio of numbers and the corresponding output a Guess. Once a user makes a Guess. If the user enters a sequence that follows the rules, output “Yes!” Otherwise output “No.”

• Treat any other entry as an exception.

Design the logic in pseudocode for Bugz App software company that sells a software package
as follows.
1. The retail price of the package is $99
2. Quantity discounts are given on purchases of 10 or more units as follows The program
must allow the user to enter the customer’s name and number of units purchased, and
output the original cost of the units purchased, the percentage discount given, the dollar
amount of the discount given, and the final cost after discount.
1. If the customer purchases up to 19 units, they receive a discount of 20%
2. 20 to 49 units – discount of 30%
3. 50 to 99 units – discount of 40%
4. 100 or more units – discount of 50%

Instructions

Download and modify the Lab5.cpp program.

Currently the program will read the contents of a file and display each line in the file to the screen. It will also display the line number followed by a colon. You will need to change the program so that it only display 24 lines from the file and waits for the user to press the enter key to continue.

Do not use the system(“pause”) statement.

using namespace std;

int main()

{

ifstream file; // File stream object

string name; // To hold the file name

string inputLine; // To hold a line of input

int lineNum = 1; // Line number to display

// Get the file name.

cout << "Enter the file name: ";

getline(cin, name);

// Open the file.

(Website Registration Form with Optional Survey) Create a website registration form to obtain a user’s first name, last name and e-mail address. In addition, include an optional survey question that asks the user’s year in college (e.g., Freshman). Place the optional survey question in a details element that the user can expand to see the question.

Describe some design trade-offs between efficiency and safety in some language you know.

Write a Java program that uses printf, and takes user input to find the name of the File.

1. FileCompare (20)

Write a program that compares to files line by line, and counts the number of lines that are different. You can use file1.txt and file2.txt when testing your program, but you must ask for the file names in the input.

main

Interactively requests the names of the two files, after creating the Scanner for the keyboard.

Creates a Scanner for each of the two files.

Calls countDifferentLines with references to the two Scanners as parameters and accepts an integer return value.

Prints the result (see sample).

countDifferentLines

Accepts references to the two Scanners as parameters

Compares the two files line by line – They may have a different number of lines

Return the number of lines that are different

Sample output

Please enter name of the first file to compare: file1.txt

Please enter name of the second file to compare: file2.txt

The files differ in 4 line(s)

(Creating an Autocomplete Form with a datalist) Create an autocomplete input element with an associated datalist that contains the days of the week.

in MIPS assembly, ask a user for two numbers and to either enter a '1' for addition or '2' for subtraction. using jal, jump to the appropriate procedure for additing or subtracting. then print out result and ask if there is another calculation (terminate program if 'no').

In coding language C, Write a program in which will use floating point variable (input=232.346) and print out: 1. scientific notation form of input. 2. floating point form of input with total width 12 (default right aligned). 3. floating point form of input with total width 12 (default right aligned) and add 0s for unused space. 4. floating point form of input with total width 12 (left aligned). 5. floating point form of input with total width 12 (default right aligned) and limit number of digits after decimal point to 2 i.e. (precision of 2 digits)
