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
Sep 27, 2013On my program I use a counter to count to 10, then i ask for a string, in this case "yes" or "no", during the count, i want to keep the user from putting inputs in, due to the fact that if they put both "yes" and "no" before the program reads the string.

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 :: Picking And Choosing Between User Inputs
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++ :: Enter As Many Numbers Until User Doesn't Type E To Exit
Oct 27, 2013Enter as many numbers as you want as long as the user doesn't type 'e' to exit.
Problem: When I enter a number, it works fine, but if I enter e then it'll go in an infinite loop since the letter is being stored in an int variable. How can I (when I press 'e') make it convert to a char to make it end the program?
#include <iostream>
using namespace std;
int main() {
int num;
cout << "Enter a number or press e to exit:";

Our class has just started c++ and we have not learned arrays and classes yet, so I'm guessing there is a way to do this without it? Or no?

C :: Stomp Size Of Array With What The User Inputs?
Apr 5, 2013How can I stomp the arr size of 50 with the value the user inputs? The function doesn't sum up the even integers from 0 to the value the user inputs. Instead it sums up exactly that many even integers.
Is there a way I can stomp the size of the array with what the user inputs so that the sum calculation never goes past the value the user inputs?
Code:
void sumIntegers () {
int arr[50];
int i = 0;
int num = 0;
int sum = 0;

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 << "

C++ :: Random Number Generator - How To Get User Inputs
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++.

So I originally used string but I heard from Daleth that Char was better, but I don't know how to apply it. I figured out cin.fail, but I've yet to finish this part.

C# :: DataGridView - Context Menu To Show Up When User Right Clicks On Fifth Column
May 22, 2014I have a datagridview with many columns. I want a context menu to show up when user right-clicks on the fifth column (column index = 4).
private void dgv_CellMouseClick(object sender, DataGridViewCellMouseEventArgs e) {
if (e.Button == MouseButtons.Right) {
DataGridView.HitTestInfo hit = dgv.HitTest(e.X, e.Y);
if (hit.ColumnIndex == 4) {
contextMenuStrip1.Show(Cursor.Position);
}
}
}
The problem is, the hit.ColumnIndex value is either 0, -1 or 1, no matter where I click. So the condition never met and the context menu never shows up. Why the values 0, -1 or 1?
