C/C++ :: Program To Take A Number From The User And Give Reduced Sum
Dec 30, 2014i 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;

C++ :: Give Appropriate Color Code For Resistor After User Input
Sep 18, 2013I am in the process of writing a program that will give the appropriate color code for a resistor after the user enters an integer value for the resistance needed and selects the tolerance form a list. My question is this: Is there a way to allow the user to enter a value such as 75000 and C++ use each digit separately, as if they entered 7 [enter], 5[enter], 0 [eneter]... and so on? But, then use the entire value as an integer too? Also, it should read a value such as: 45835, as 45000, or 1843 as 1800.

May 31, 2014So I'm writing a program that will read a text file and it will do certain "functions" the text file will be like a game, and the program will be able to run many different games. The problem i'm having is in one of the "functions" i believe it's the one meant to get a correct choice from a file and a user input and put them into strings, it gets the wrong input. I know this because i tested both strings the "function" writes too. it gets the correct file answer but the user input is always "c" for some reason.
#include "stdafx.h"
#include <iostream>
#include <iomanip>
#include <fstream>
#include <string>
#include <stdlib.h>
using namespace std;
int progfiles() {
[Code] ....
This is the code, most likely the section that is surrounded with "///" contains the problematic "functions." This is the command Line output...investigate why they're dieing or continue on your journey?(i-investigate/c-continue) got input and answer
i
c
i
Press any key to continue . . .
The got input and answer are tests to make sure it got both, the first 'i' is my input, the 'c' is what it says my input is, and the 'i' is the correct answer from the file. this is the part of the file that the program reads to get that output
"1 Do you want to go investigate why they're dieing or continue on your journey?(i-investigate/c-continue) 2 8 i 7 3 4 You continue on picking up speed to get to the egg first.. and.. Oh No, You accidentally bumped into the walls! 2 12 5 1 You go over, and as you realize the walls are acidic and that's why the other sperm are dieing.. 2 6"
C :: 2 User Inputs For Calculation
Apr 9, 2014I want to have calculations take place inside a switch statement that calls the appropriate function. The menu portion of the program works well, but I can't figure out how to let the user actually input 2 different numbers to the functions. My questions are:
1. If I use scanf to assign values to the variables, what determines end of input to each variable? (ie.. scanf("%d%d", &a, &b) what is the end of a, what is the end of b?)
2. Should I assign the variables to user input inside the switch, or try to do it in the functions below?
3. Is there something I haven't thought to ask that will screw me over? I'm really new to this.
Code:
#include<stdio.h>
int add(int b, int a);
int mult(int b, int a);
main() {
[Code] ....
This really was a test of multilayer menu, but I want to add functionality if I can.
Changed a variable before posting and didn't change all the conditions testing it.
C :: Keep User From Putting Inputs

C :: How To Put What The User Inputs Into Array
Jul 23, 2014I have a project that requires I take user input from menu options and put it into an array which I will average out. I can set the menu up I think, but I cannot understand how to put what the user inputs into an array. Granted I just took the lecture on arrays today. Also we can only use functions to do the work.

C++ :: Error Message While Debugging
Mar 17, 2013 I'm getting an error message that I can't seem to fix. The error clearly states that during the link aspect of the debugging and build there is an error that says that the stdio.h file is either missing, invalid or corrupt. When I try to program using any of the other headers I'm getting the same error. The files are there I can see them in the include folder, so I'm asking what can I do to fix all these headers and beware I am a beginner at programming and using any kind of compiler.
This is the error I receive.

This is the compiler I am required to use for an online course and all instruction is given for the Microsoft visual 2010 express edition. Also the only file I think that's being referenced is the #include <stdio.h>.

Jul 31, 2013I have recently looked into a self created project where I wanted to compare user input against a list of strings in an external file. That has since been completed to my great satisfaction, however it did throw up some interesting issues in my knowledge and understanding of user input..What is the best way to pick up user input i.e scanf,stdin etc. and when should either be used and can a mixture of types be used, and if so, when and why.
A quick program to take different input methods and display differnt output method (obviously corresponding i.e scanf/printf - fgets/fputs)
My first pothole came when I have setup the method for scanf - fine. Then I setup the method for fgets(test,100,stdin) for example and the fgets method no longer picks up stdin from the user..
C++ :: calculating Sum Of Numbers Between Two User Inputs
Mar 17, 2014How to calculate the values between numbers that a user types in.
Write a function which takes two parameter of integer type and both parameters are positive integer. These number should be provided by the user of your program. The first parameter is lower than the second parameter. You function should be able to calculate the sum of the square of each of the numbers between the two inputs and should display that. Please write a main function to display the working of your function. Call the function at least three times by using some loop in the main function.
C/C++ :: Linked List Inputs From The User?
Sep 8, 2014#include <iostream>
using namespace std;
void insert(int data, int positionOf_n);
void print();
struct node {
int data;
struct node *next;
[code]....
this is the original code which use the insert function call in the main as predefined that doesn't allow the user to input the value that they want
#include <iostream>
using namespace std;
void insert(int data, int positionOf_n);
void print();
struct node {
int data;
[code]....
and this the code which i tried to replace the limitation of the above code by using two for loops in the main function instead of the <insert(5,2)> from the above code which allow the user to insert it own values to the linked list, but it keeps crashing.

C++ :: Create Fibonacci Sequence With Some User Inputs
Aug 26, 2013I'm trying to make a fibonacci sequence with some user inputs. I'm using arrays for this, the user inputs are for the Nth term and the starting number (as in the number in front of 0).
My problem is that when the program runs it's an infinite loop which constantly prints the starting number. Which, I think, means that my WHILE loop isn't coming to an end and my 'count' variable isn't increasing.
#include <iostream>
using namespace std;
int main() {
int start;
int term;
cout << "Input a starting number for the sequence: ";
cin >> start;
cout << "

Sep 10, 2013I want to program a program that produces a random number between 1-10, then if the number is correct, says like HEY GOOD JOB and if its not says try AGAIN! also, at any point the user can quit by typing in X.
I know that I can use stuff like cout << "Hey put in a guess now" to prompt the user but I dont know how to accept inputs.
For example, how do I use scanf to do this?
I know that if I use scanf, it takes in a value, but where the heck does it store it?
eg. scanf(%s,guess);
Is that valid? I get an invalid expression error when trying to use that in C++.
