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
I'm making a program that prompts a user for an int value. The value input by the user must be a multiple of 16. If it is not, I must return an error message.

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;

-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).
This is what I have so far:
#include <iostream>
using namespace std;
int main() {
int a;
int b;

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

Write a program that prompts for and reads in test scores. You may assume that valid test scores will be integer values between 0 and 100. You may also assume that the user will not enter more than 35 test scores. Use a preprocessor directive to define this value. User input will be complete when the user enters a -1 for the test score. When all of the test scores have been entered, the program will print out the scores. Use a while or do-while loop to read in the values. Use a for loop to print out the values.
Sample output:
Enter test score 1: 88
Enter test score 2: 67
Enter test score 3: 74
Enter test score 4: 94
Enter test score 5: 79
Enter test score 6: 56
Enter test score 7: -1
Number of scores entered: 6
Test scores entered : 88 67 74 94 79 56
I have created a generic array-like template to create arrays of different types. Now I need to get user input from a menu about which type of array they are building. I tried having the user enter a number and using that number to pick a string from an array of constant strings. But pretty obviously, that threw a type conversion error. Is there a way to convert the literal string of a type into it's type or refer to a type directly.
Here is the code I need to fit a type into at runtime:
SimpleVector<TYPE> myVect = SimpleVector<TYPE>(dataSize);
I know how to open a specific files by using
ifstream infile("something.txt");
but how do you let the user select an arbitrary file from the working directory?
Write a user-friendly C++ program that allows a user to select repeatedly an operation to be performed from a displayed menu of actions. The menu includes the following items:
1. Simple Statistics
2. Vector Addition
3. Dot Product
4. Exit
The menu actions are described by the following points:
Simple Statistics: This action includes finding the average, and standard deviation of a list of data items. The option should allow the user to specify the name of a file from which the data are read into an array. All the results of this option are displayed on the screen.
Vector Addition: This action allows the user to enter the name of a file from which two vectors, V1 and V2, of equal size N are read. Accordingly, the two vectors are added, and displayed along with the resultant vector on the screen. Your program should check that the two added vectors are of the same size. Otherwise, the program should display a message and allow the user to make another choice from the menu.
Dot Product: This action is similar to the Vector Addition in terms of input, output, and checking validity of the vector operands.
Exit: This action terminates the program.
Your program should include at least the following functions:
1. A function, called ReadVector(), which reads a vector of any size from a given file name, and returns the vector and its size to the caller. The function prototype is defined as follows:
void ReadVector(double V[], int &size, ifstream infile);
2. A function, called DisplayMenu(), which displays the menu and returns the user’s choice as an integer value between 1 and 4. The function prototype is defined as follows:
int DisplayMenu (void);
3. A function, called VectorAdd(), which performs the addition of two vectors, A and B, and returns the resultant vector, C. The function prototype is defined as follows:
void VectorAdd(const double A[], const double B[], double C[], int size);
The sum of two vectors, A = (a1, a2, …, an) and B = (b1, b2, …, bn) of size n, is defined as: C = A + B.
Where, C = (c1, c2, …, cn), and ci = ai + bi, for1 i n .
4. A function, called DotProduct(), which performs the dot product of two vectors, A and B, and returns the result. The function prototype is defined as follows:
void DotProduct(const double A[], const double B[], int size, double &result);
The dot-product of two vectors A = (a1, a2, …, an) and B = (b1, b2, …, bn) of size n is defined as
n n
n
i
i i b a ....... b a b a b a B . A
1 1 2 2
1
5. A function, called Simple_Stat(), which finds the maximum, minimum, average, and standard deviation of a list of data items passed to it by a one-dimensional array. The function returns the average and standard deviation values. The function prototype is defined as follows:
void Simple_Stat(const double list[], int size, double &average, double
&std_dev);
So I'm trying to make a program that asks the user for a number and then prints a statement the same number of times the user entered. 3 different statements, using the 3 loops (for, while, and do while). I made the program but for some reason the statement from the do while loop goes off infinitely.
MY CODE:
The error:
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.
i have only recently got into programming. i have this homework assignment that is frying my brains, the program needs to take a number from the user and give the 'reduced' sum. for example: if the user enters 888 then the sum should be: 6. it takes the number and adds its digits im just looking for a direction to where my problem is
#include "iostream.h"
int reduction (int number) {
return number/10+number%10;
}
int main() {
int number,loopcount;
cout<< "please enter a number"<<endl;
cin>>number;

I'm trying to create a program that prints a number of dots specified by the user, there 4 options to do any loop type or to exit the menu. i'm having problems making it so that after you enter a value and it displays the specified number of dots it clears the results. Also we have to make it so that if a negative integer is entered it still prints out the appropriate amount of dots ie: user puts -9 it prints 9 dots, i know you use the abs() function but it doesn't seem to be working for me. I'm assuming my problem with the abs function is i'm not using it correctly. Use case 1 as the example for the rest because I'm trying to implement everything on one case at a time
Code:
int main() {
//initialization statements
int Num1 = 0;

Im trying to create a program that has the user input a 5 digit number. If it's between 10000 & 99999, it will do one thing..(just saying 'yes' for now. Outside those numbers will prompt the user to input again. However, if the user inputs the exact digits 76087, it should display 'term'.
This current code is displaying 'term' whenever the user inputs the 5 digits.

int main() {
int pin;
cout << "Welcome to Movie Food
Enter your 5-digit pin code: " ;
