im working on our project and this part of the project which says to add a new a room.
Details:
Open the file (ROOMS) that maintains all the ROOMS records.
Ask the user to enter the required data Room_Type and Room_Rate, then save it.
Keep asking the user (Do you want to continue?) until the user enters (N OR n), this should stop the data entry and get the user back to the main menu.
Myproblem :: i keep getting error at the bottom says my while statement is wrong " IntelliSense: no operator "!=" matches these operands"
My other problem:: how do i get back to the main menu?
so what ive done till now is.
#include <iostream>
#include <fstream>
#include <string>
using namespace std;
int main() {
int choice,i=1,Room_rate;
string alphabet;
string Room_type;
I have the program working but when I check if the input to make sure it is not a char it creates a infinite loop. I used an if statement to check for the issue and solve it but its not working. I even tried throwing an exception but I learned later they are not used for things like this.
Code: #include <iostream> #include <limits> #include "contacts.h" using namespace std; int main()
The code below replaces lowercase characters by upper case and uppercase character by lowercase. Also, I should be able to break out of the loop when I enter 'exit'. It does what it is supposed to do. But I had to come up with a function to break out of 'the while loop'. Is there any shorter or more concise way to break out of the loop when 'exit' is entered?
I am trying to do a while loop that terminates the program when 99999 is entered but otherwise allows infinite integers to be entered. My problem is that when a negative number is entered it crashes and also when I enter a number it displays it twice.
#include <stdio.h> #include <stdlib.h> main() { int number; printf("Input an integer. "); do { scanf("%d",&number); /* read a single integer value in */ printf("%d ",number); } while (number != 99999); }
I was asked to create a loop that outputs until Quit is entered for customer name. This is what my output is suppose to look like: I will also attach the code I made. Im sure there is something wrong with my while command. But I believe there is something else I have to add to print out the last customer name: quit output.
Keep track of the sum of values entered (as well as the smallest and the largest) and the number of values entered. When the loop ends, print the smallest, the largest, the number of values,and the sum of values. Note that to keep the sum, you have to decide on a unit to use for that sum; use cm.
I'm working on a code that needs to loop a switch case back to the beginning after a certain input is entered.
ex) Code:
printf("Select an option); printf("1. Play game"); printf("2. Status"); printf("3. Exit"); scanf("%i", &userinput); switch(userinput);
[Code]...
For my program, I want option 2 to display something, then loop back to "select and option" after the user presses enter. How would I write that? Would i use a while? do while?
I am stuck on an exercise where i am supposed to use a loop to take user input and keep a running sum until the user enters a 0. the code i have so far is:
#include <iostream> int main() { using namespace std; int num; int total = 0; int x;
[Code] ....
The full text of the error message is: error c2678:binary'>>':no operator found which takes a left-hand operand of type 'std::istream' . and one more thing i was wondering, is there a difference between c++ and visual c++?
I'm currently working on a project that utilitzes a Caesar Cipher. Basically, it reads input from a file and then, depending upon the input file, requires encrypting or decrypting. The cipher used to encrypt/decrypt simply adds/subtracts an integer from each character in the input file. All input is lowercase alphabetic characters (ASCII 97-122). My problem is trying to figure out how to wrap the ciphered characters, e.g., if the cipher require a shift of +5 and the character read was 'x', a shift of +5 to the right would produce 'c' (beginning with 'x' and counting up 5 letters: 'y', 'z', 'a', 'b', 'c').
I've written some crude and cumbersome loops that will work, but there has to be a better way. It is my understanding that it can be done using the modulus operation, %, but I cannot figure out how. I spent several hours trying to figure out the modulus approach, but no luck.
I'm trying to make an alphabet soup on C programming, and I'm stuck with a problem.I need to make a function able to automatically find all the words that exist in alphabet soup.
I know how to store numeric data using keywords int, long, float, and so on. I'm making my own program called "Who is your soul-mate".The only question I want to ask is what's the keyword for storing alphabet data? As you can see below on my source file. I want to replace "int" keyword with another keyword that can store alphabet data. It's all in standard C.
#include <stdio.h> int soulm01, soulm02, soulm03; int year_of_birth; int main(void)
Be given a string of chars, where each single char belongs to the following alphabet: a..zA..Z0..9 (So, in the string there are only lowercases, uppercases and digits. No blank, no comma, ...).
For every char of the given alphabet, count how many times in the string
1----- the char is preceded by its predecessor in the alphabet (consider that the predecessor of 'a' is '9') 2----- the char is followed by its successor in the alphabet (consider that the successor of '9' is 'a') 3----- the char belong to a sequence of identical chars whose length is at least three (i.e.: in the string cc74uyrpfccc348fhsjcccc3848djccccc484jd for three times the character 'c' satisfies this condition) 4----- what is the longest substring of characters strictly rising (the following is greater (>) of the previous) 5----- what is the longest substring of successive characters (i.e.: fhkjshdfruytyzABCDEfglsj => 7) 6----- the frequencies of any char (if in the string the character 'g' occurs 12 times, its frequency is 12)
I am trying to find the max number entered by the user, and it should terminate when a negative number is entered. For my code, it will just end when the user inputs a lower number than the previous. i.e.- 10 20 15 "The highest number is 20" when it should be "10 20 5 40 15 -1" "The highest number is 40". No arrays or do/while loops either.
#include <iostream> using namespace std; int Max(int x); int main() { int x;
A problem that lets the user enter any positive integer, but you do not have to check for this, and then calculates the sum of the digits and displays this to user. For example, if user enters 14503, the outputted sum of the digits would be 13. You need turn in an algorithm, C++ source code and output.
how do i even go about making 1 add to 4? and so on. I'm lost.
I am currently taking a C# class. Our current assignment has us entering a player name, and number of hits and displaying these in one set of labels. I have coded everything for the primary function of this program and it works. However, I also have to have a second set of labels that show the highest number of hits entered (if I enter 44, the first and second labels change to 44; if I then enter 27, the first label changes to 27 and the second stays at 44; and if i enter 55, the first label changes to 55 and the second label changes to 55) and the corresponding player name. I have tried searching and reading and I can't seem to figure out how this is done.
I am making a program that will suggest meal options when choosing specifics contained within, e.g. style, base, main, sauce.
What I would like to know is how to collect the input that has been entered by the user, say you are given 4 lists and each has an option, how could I chain these together in order to cout a suggestion that is in my database?
------------------------------------------------------------------------------- Example (not my real Q's and A's):
OUTPUT: What meat would you like? INPUT: "Beef" //<collect this! OUTPUT: What sauce would you like? INPUT: "Tomato" //<and this! OUTPUT: What would you like to have as the main/base? INPUT: "Pasta" //<and this! OUTPUT: I can suggest... "Spaghetti Bolognese" //< and return this from the database using the 3 filters --------------------------------------------------------------------------------
