C :: Compute Permutations Of Any String Entered - Function Will Not Return A Value
Jun 11, 2013This is my program, for now it is intended to compute permutations of any string entered, but the function ox will not return the final x value. ox is the function that actually computes the permutations so the return of the x value is critical.
Code:
#include<stdio.h>
#include<string.h>
int ox(int x);
int main() {
int x;
char input[10];

C :: Program Where User Inputs A String And Prints Out Length Of String
Jan 29, 2014I would like to understand a function on strings. Below is a code that I took from my teacher where the user inputs a string and prints out the length of the string.
Code:
#include <stdio.h>
#include <string.h>
int main() {
char str[100];
int i = 0;
[Code] ....
Now I understand that it returns the count in "int" so my question is:
Let's say i declared
Code: int count = 0;
at the beginning of the code and then made
Code: count = strlen(str);
why wouldn't i have the same result? Is there a way to do it also?

C++ :: User Defined Program - Compute Price Per Square Inch Of Cake Using Overloading
Nov 21, 2014Create a user-defined program that will compute the price per square inch of a cake using an “overloading”. The cake could be a circle or a square type. In the main function, ask for the price of a circle cake and its diameter, while for the square cake, ask for the price, its length and width. The process must be done inside the different function of each cake. (Note: two sub function for the computation of a circle and a rectangle)
Note that when I made this program something weird happen. After inserting the name, all things follow.

C++ :: How To Recognize Two Words Entered By User For A String
Feb 11, 2013In 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.
C++ :: Program That Compute Final Average Grades Of Class
Jan 28, 2013An instructor needs you to write a program that will compute the final average grades in her class. There are 5 students in the class. Each student must take 2 exams and 4 quizzes as part of their final grade. The weight of each toward the final grade is as follows:
Exam 1 – 30%
Exam 2 – 30% Quiz 1 – 10%
Quiz 2 – 10%
Quiz 3 – 10%
Quiz 4 – 10%
You must use arrays to store each students 3 digit ID number, exam scores and quiz scores. A multi-dimensional array is mandatory. Request from the user the information needed then output all of the information as well as the final average grade for each student.
C++ :: How To Store Class Info Entered By User Into Array
May 7, 2013So 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();

C++ :: Cartesian Class - Display Coordinates Entered By User

C++ :: Write Program That Scans Entered String For Keywords And Responds?
Nov 17, 2014I'm attempting to write a program that will respond to me a lot like cleverbot or Siri. I can take care of making the program do the things I want it to do such as shutdown the computer, play a song, or whatever but I do not yet understand how to make it read strings I say, and make sense of them using certain words in that sentence. I could probably make an endless if statement to see if a string entered (using cin on a string[]) matches a certain other string, covering a million different sentences with a million different combos of words and spelling and capitalization but I want to enter a sentence and have the program search for keywords and then act on them. For example, with "shutdown" and "computer" being the keywords that make the program run the shutdown operation, so that whether I say "Yo, program, shutdown this computer for me!" or "Shutdown this computer", it will use the common terms here, "shutdown" and "computer" to know what to do.

Jul 15, 2014I 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.

C :: Checking What User Has Entered (City)
Mar 9, 2013I am using Dev C++ on a windows computer.

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.
C++ :: How To Use A User Entered File In Fstream
Feb 14, 2014So, 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.
C++ :: How To Collect Input That Has Been Entered By User
Mar 19, 2013I 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

C/C++ :: Creating Constant At Runtime With User Entered Value?
Aug 14, 2014At 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?
C/C++ :: Finding Sum Of Values Entered By User In While-loop?
Aug 26, 2014Keep 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.
