Programming & Computer Science Answers

Write a C++ function, smallestIndex, that takes as parameters an int array and its size and returns the index of the first occurrence of the smallest element in the array. To test your function, write a main that prompts a user for a list of 15 integers and outputs the index and value of the first occurrence of the smallest value.

An example of the program is shown below:

Enter 15 integers: 
1
2
3
4
5
6
7
8
9
0
10
11
12
13
14
1 2 3 4 5 6 7 8 9 0 10 11 12 13 14 
The position of the first occurrence of the smallest element in list is: 9
The smallest element in list is: 0

You can use the following integer lists to test your code:

• 56, 34, 67, 54, 56, 87, 66, 92, 15, 32, 55, 54, 88, 92, 30
• 79, 26, 97, 87, 73, 44, 67, 46, 55, 13, 20, 20, 33, 42, 60
• 63, 1, 40, 81, 30, 11, 26, 44, 98, 1, 80, 98, 15, 3, 42

Instructions

Write a program that prompts the user to enter a string. The program outputs the sum of the values (collating sequence or ASCII value) of the characters in the string. For example, if the string is "spring", then the sum of the values of the characters is 115 + 112 + 114 + 105 + 110 + 103 = 659.

An oil slick occurs when an underwater refinery pipe ruptures, pumping oil into the water. The spilled oil sits on top of the water and causes a natural disaster. For simplicity, suppose that the oil sits on top of the water in the form of a circle.

Instructions

Write a program that prompts the user to enter the rate at which the ruptured pipe pumps oil (in gallons) per minute, the thickness of the oil on top of the water, and the number of days for which the area is covered by the spilled oil. The program outputs the spilled area (in kilometers) and the volume of oil (in gallons) on top of the water after each day.

Format your output with setprecision(8) to ensure the proper number of decimals for testing!

You are given a file consisting of students’ names in the following form: lastName, firstName middleName. (Note that a student may not have a middle name.)

Write a program that converts each name to the following form: firstName middleName lastName. Your program must read each student’s entire name in a variable and must consist of a function that takes as input a string, consists of a student’s name, and returns the string consisting of the altered name to print to the terminal. Use the string function find to find the index of ,; the function length to find the length of the string; and the function substr to extract the firstName, middleName, and lastName.

Write a program that uses a random number generator to generate a two-digit positive integer and allows the user to perform one or more of the following operations:

1. Double the number.
2. Reverse the digits of the number.
3. Raise the number to the power of 2, 3, or 4.
4. Sum the digits of the number.
5. If the number is a two-digit number, then raise the first digit to the power of the second digit.
6. If the number is a three-digit number and the last digit is less than or equal to 4, then raise the first two digits to the power of the last digit.

After performing an operation if the number is less than 10, add 10 to the number. Also, after each operation determine if the number is prime. Each successive operation should be performed on the number generated by the last operation. Your program should not contain any global variables and each of these operations must be implemented by a separate function. Also, your program should be menu driven.

Write a program that prompts the user to input a string. The program then uses the function substr to remove all the vowels from the string. For example, if str = "There", then after removing all the vowels, str = "Thr". After removing all the vowels, output the string. Your program must contain a function to remove all the vowels and a function to determine whether a character is a vowel.

The Programming Example: Pig Latin Strings converts a string into the pig Latin form, but it processes only one word. Rewrite the program so that it can be used to process a text of an unspecified length. If a word ends with a punctuation mark, in the pig Latin form, put the punctuation at the end of the string. For example, the pig Latin form of Hello! is ello-Hay!. Assume that the text contains the following punctuation marks:

• , (comma),
• . (period),
• ? (question mark),
• ; (semicolon),
• : (colon).

Exercise 16

A new author is in the process of negotiating a contract for a new romance novel. The publisher is offering three options. In the first option, the author is paid $5,000 upon delivery of the final manuscript and $20,000 when the novel is published. In the second option, the author is paid 12.5% of the net price of the novel for each copy of the novel sold. In the third option, the author is paid 10% of the net price for the first 4,000 copies sold, and 14% of the net price for the copies sold over 4,000. The author has some idea about the number of copies that will be sold and would like to have an estimate of the royalties generated under each option. Write a program that prompts the author to enter the net price of each copy of the novel and the estimated number of copies that will be sold. The program then outputs the royalties under each option and the best option the author could choose. (Use appropriate named constants to store the special values such as royalty rates and fixed royalties.)

1. Define an enumeration type triangleType that has the values scalene, isosceles, equilateral, and noTriangle.
2. Write a function triangleShape that takes as parameters three numbers, each of which represents the length of a side of the triangle. The function should return the shape of the triangle. (Note: In a triangle, the sum of the lengths of any two sides is greater than the length of the third side.)
3. Write a program that prompts the user to input the length of the sides of a triangle and outputs the shape of the triangle.

During winter when it is very cold, typically, everyone would like to know the windchill factor, especially, before going out. Meteorologists use the following formula to compute the windchill factor, W:

W = 35.74 + 0.6215 × T - 35.75 × V^0.16 + 0.4275 × T × V^0.16

where V is the wind speed in miles per hour and T is the temperature in degrees Fahrenheit.

Instructions

Write a program that prompts the user to input the wind speed in miles per hour, and the temperature in degrees Fahrenheit. The program then outputs the current temperature and the windchill factor. Your program must contain at least two functions: one to get the user input and the other to determine the windchill factor.
