I would like to know the algorithm or flow for finding unequal elements in an array entered by user. I tried using for loop but didn't get the expected output
Code:
#include <iostream>
#include <string>
using namespace std;
int main() {
int a[10],b[10]; //array of integer elements

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;

How to find the largest and smallest number entered by a user. So far I'm able to add, find the average and count how many numbers are entered.
I'm just having trouble with find the max and min. I tried if statements and it breaks the program will it wont let me exit the while loop or the program will do a force close after entering a value.
Code:
#include <stdio.h>
#include <stdlib.h>
int main(){
int maxNum=0, minNum=0, value, count=0, sum=0;
double average;

The program should find and delete all vowels in a word that is user entered. This is what I have so far and I know it should be essentially this format I just don't know how to set enteredword and word equal to each other.

using namespace std;
void vowelremover(string&);
int main () {

I am trying to write code to find all the prime numbers before a user entered number. I started with a working program and when I tried to create a function, it got all messed up.
Code:
#include <stdio.h>
int is_prime( int num );
int get_positive_integer(void);
int main( ) {
int upper; /* upper limit to check */
int num; /* current number to check */
int isprime;
/* used to flag if number is prime or not */

It says the error is on line 23
So I have an array of my own class, "Restaurant," but I'm having a hard time figuring out how to store the info entered by the user into the array.
In total, I have two classes. I will show you all I have, it's a lot but I know it will be easier to understand.
My problem is in the AddRestaurant(), since that is where I should ask the user for all the information and store it in the array.
Also consider that I have to use the FTime class as well to handle the time. Basically I want to do something like this:
info[count].SetRating();
which will put the rating part of the class Restaurant into the array[count]
Also, my program doesn't compile because of the AddRestaurant and PrintAll functions since what I am showing is what I want to do, not what works.
//main.cpp
#include <iostream>
#include <iomanip>
#include <string>
#include "Restaurant.h"
#include "FTime.h"
int ReadMenuChoice();

exercise in c: write a program which calculates % of even numbers entered by a user in an array;
1) check if user hasn't entered float value; if has issue warning;
2) give the option for user to press "stop" to exit program any time.
int c,sk[100],i,sum1=0, sum2=0, rel;
printf ("How many numbers will you enter?
");
scanf ("%d", &c);
printf ("Enter %d numbers (to exit program press - stop)
", c);

I have an if statement that should either match a text variable that the user has entered and a another text variable that has been got from an array but they won't match even if they are the same,Im at a lost with it.

I need to create a program that will find the total of all the elements in array. I need to use for loop and the array size is 10.The output should be like this: i used user input
Input array 0 : 2
Input array 1 : 4
Input array 2 : 6
Input array 3 : 7
Input array 4 : 8
Input array 5 : 9
Input array 6 : 10
Input array 7 : 12
Input array 8 : 16
Input array 9 : 20
Sum of 10 numbers in an array is = 94..Press any key to continue..I have a code but the output is not like that. Here is the code,
// Program to store 10 integers array
#include <iostream>
#include <stdio.h>
using namespace std;
int getArray(int x[]);

Develop a function that finds the greatest difference between two consecutive elements stored in an array. Develop a 9 element array of doubles to test your code. Print to the screen which two numbers have the greatest difference as well as the value of the difference. Finally include an overloaded version of the function that will work if the array is composed of integers. Include your code used to test this function.

I read up online as well as my book and looked at sample programs, then created mine which was similar to the sample programs I looked at, but the sample ones compile , while I get C2059 and C2061 Syntax Errors. I am new to programming so I understand it could be one small thing but I after looking over it I am completely clueless.
Heres my program:
Code:
#include
<iostream>
int
main()
[Code] .....
My program is also attached
So I'm trying to sort an array of 10 elements provided by the user. For Example:
Person 1: 5
Person 2: 3
Person 3: 9
etc etc...
I want it to also pair the value with the person. So it should read:
person 3: 9
Person 1: 5
Person 2: 3
Sort the values in descending order.
I can sort the array, but I cant get the Person number to pair with the value...

In my code, the user enters the name of a city, and then according to what city it is, the program displays the coordinates of that city
I can't find a way of figuring out and checking which city the user has entered so the code can displays its appropriate latitude and longitude.
So, I am making a name-database-type-thing and I want the user to be able to enter there own file. Like, here:
string fileName;
string name;
cout<<"What is your file name?"<<endl;
getline(cin, fileName);
ifstream nameFile(fileName);
getline(cin, name);
nameFile<<"Name: "<<endl;
Well, that last part is in a loop, so you can enter an unlimited number of names to the .txt file.
So, it won't let me use the string in ifstream. How can I fix this? This maybe unclear, so if it is just say so and I will edit it.
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

how I can ignore strings from being entered by the user. When the use enter's a string it always evaluates it as even. I though I might use a cin.ignore(); but I am unaware of how to use it.

In my little experiment i am trying to get the compiler to recognize 1 word with 2 parts from a list of names.
For example: if the user wanted to choose "candy bar", from a list of items which include: "candy bar", "cat", "dog"
My current code can recognize words without a space like cat and dog. But how can i recognize candy bar?
I tried using getline but its of no use.
At the moment I am making program that will use a 2d selection of "cells" to make a "map" of sorts. However, the size will not be known until run time.
I figured using an array would good, because once the size is chosen it won't be changed. However I can't create an array without using a constant.
So the first question is, can I create a constant at run-time with a user entered value that can then be used for an array size? If so, how?
Otherwise, what are my options to achieve this? I know vectors can be used, but A, my compiler keeps giving me problems even when C&P some code bits (yes I even remembered to #include and such) and B, I noticed that vectors reserve extra memory for when the size changes but this is bad (well my dinky little program won't notice, but trying to set good habits as I learn, so I'm keeping it in mind) as I don't need and don't want to allow the size to change after creation.
Which leads to number three, if I do have to use vectors, how can I prevent any accidental size changes after the initial size is determined?
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.
