Write a program that prompts the user to enter an item#, the program should determine if the item is in the file and print the price of the corresponding item. If the item is not in the file an error message should be printed.
All I have so far is
string item_no=0;
cout<<"Enter a item#";
getline(cin,item_no);
if stream openData;
I need to finish the rest in pseudo code
Write a program that prompts the user to enter an integer and then displays that integer as a product of its primes and if it is a prime then it should say so? Above is the question I have been given
#include <iostream>
#include <vector>
using namespace std;
int main () {
int num, result;
cout << "Enter A Number " << endl;
system ("pause");
return 0;
}
This is what I have so far, do I have to use a for loop, a while loop or a do loop,
Here is the whole code:
#include <iostream>
#include <ctime>
#include <cstdlib>
//This program prompts the user to select a number between 2 and 12
//computer throws two dices
//player win if selected number matches the sum of the two dices thrown by computer

Write a program that asks the user to enter a student’s grades on four exams. The program should display the four grades and the average of the four grades,rounded to the nearest tenth. To add the grades, use a variable called total_grade, which you should initialize to zero.As the program prompts for and obtains each grade, add the grade to total_grade using the += operator.

EXAMPLE

Write a C++ program that asks the user to enter an even number only. If the user enters an odd number the program should use input validation to ask the user to enter another number.
- The user can enter as many numbers as he wants
- The program should also keep a count of how many numbers entered and display how many odd and even numbers entered.

The program has to us see a while loop and display the income total, expense total, and total profit or loss. I've got it really close, but I'm doing the loop wrong. It counts the sentinel value (-1) towards the total, instead of just ending like it is supposed to.

i'm trying to write a calculator. the user will enter the terms and they will be stored in arrays. i will be storing those terms in string arrays and then later turn them to double to work with them. but the user should be able to enter terms like sin(252) and the program should be able to recognize it and calculate it.
View 4 Replies View RelatedI am trying to write up something to have a user to enter a four digit number. Only four digits, Ex: 0001, 0116, or 9999. There is no getting around the selection 0001 or 0002. I understand if not done correctly, the first three 0's will be ignored.
I've been just playing around with what I have below but I just don't remember how to do it nor can I find a good example online to figure it out. I know it is not correct just typing to try to remember. I am aware that it is gibberish right now, this is just me brainstorming.
int number;
cout<<("Please enter the four digit number(Ex: 0001):
");
cin>> setw(2) >> number;
cout<<)"Please enter four digit date. Two digits for month and two digits for year:
");
cin>> date;
if (number< || number > 30)
cout << "Invalid choice. Try again." << endl;
cin.clear();
I'm stuck because I can make the calculator just find but the user will have to press enter after every number, what is s solution to this?

B. Circle in a Square Write a C++ program that will ask the user to enter the area of a square. Then the program will display the biggest area of a circle that will fit in a given square. Using math.h library is not allowed.
View 1 Replies View Related-Write a program using while loops that prompts the user for a set of integers.
-Your program will ask for one integer at a time. If the number 0 is entered, the list is complete and your program will output two results: the sum of the even integers and the sum of the odd integers.
-After each integer is entered by the user, your program will print out whether the integer entered by the user is less than, equal to, or greater than the previous integer. Assume for the first integer entered by the user that the “previous integer” was 0.
-Your program must handle a variable number of inputs (in other words, you cannot hard code for the test cases).

the problem that I'm running into is that the compiler skips to the end when I put my initials in //User input > "Initials"
I'm using Microsoft Visual C++ 2010 Express.
Here is the assignment:
Plan and code a program to do the following. You found an exciting summer job for 5 weeks. It pays $15.50 per hour. You will input the number of hours per week that you worked and then compute your total earnings. You must pay taxes of 14%. After paying taxes, you will spend 20% of your money on cloths and 5% on school supplies. After buying clothes and supplies, you will use 25% of the remaining money for savings.
Input
Your 3 initials and the hours for each of the 5 weeks. Use the following numbers of hours for your first test 25, 30, 20, 23, 22.
Calculations
Gross pay is the rate of pay times the sum of all hours you worked. Use CONSTANTS for each of the following rates:
Tax rate 14% of the gross earnings
Clothing 20% of earnings after taxes
School supplies 5% of earnings after taxes
Savings 25% of earnings after taxes and expenses
Output:
Output your initials, total hours worked, gross earnings, taxes, net earnings after taxes, clothing expense, supplies expense, amount going to savings and amount left to spend. Output must be aligned to the right as shown with 2 decimals in all numbers. Sample output:
Initials ABC
Total Hours Worked 120.00
Gross Earnings 1860
Taxes paid 260.40
Net Earnings 1599.60

View 2 Replies View RelatedMy assignment is : Please use C type strings ( array representation of strings). Write a program that will ask the user to enter a string. It will then regard that string as a worked-on string and allow the user to perform the following editing functions on it:
s – search
i – insert
a – append
d – delete
a – append
d – delete
r – replace
e – exit
s – search
This option will allow the user to search for a specified string in the worked-on string. If the string is
found, it will display the starting index (position) of the searched string in the worked-on string.

You enter decimal number into the program and what base you want. The integer part of the decimal is being handled fine, but the decimal is not.
For example, I enter 15.6847 and base 10, which means I'm going from base 10 to base 10. It spits out 68469999999999 for the decimal part. (Do not worry about the first block of numbers. The second block seperated from the first by a space is where the decimal will appear in order.)
