I'm trying to create a connect four game, but I've ran into a problem while trying to read valid user input.
Code:
// 4 in a row game
#include <stdio.h>
#include <stdlib.h>
#define NUM_ROWS 6
#define NUM_COLS 7
}
[code]...
If the user enters an invalid number, then it works fine, but if a character is entered, the while loop in main never breaks.
I have tried to submit this topic before but i didn't submit my whole code and it was removed. So here it is. All I am trying to do is load form2 from form1 then back to form1 from form2 for a certain number of times the get out of the loop. I am new to C-Sharp and it seems as though I cant seem to figure out a way to do this.
Here is form1 and form2 code. I have commented out a few things I have tried.
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
[Code]....
I found a for loop in an example that I don't understund fully.
Code:
for (i=64; i; i/=2)
printf("i: %d
",i);
Now this is dividing by 2 until it reach '1' and stops. But why does this stops?
Having multiple issue trying to get a while loop to stop after the third entry.
#include <iostream>
#include <fstream>
#include <string>
#include <stdlib.h>
using namespace std;

string line;
[Code] .....
I am just working on the while loop right now. Then the function after I get the loop working.
I wondering how to stop a infinite loop. The program clears a file then opens it and refreshes it over and over(the file is going to be modified by another program). I want it to start from the beginning anytime i press enter or escape, it doesn't really matter as long as you can restart it.
Here is the complete code:
#include <cstdlib>
#include <iostream>
#include <fstream>
#include <conio.h>
#include <windows.h>
using namespace std;
void x() {Sleep(1000);}

I'm new to C programming and am quiet lost, create a program that takes a start and stop time and prints the passed, or show me where I can find the information needed?

View 2 Replies View RelatedJust a quick newbie question: I'm doing a console application and whenever I open a .exe using system(), the console pauses and does not run the next instruction until I close this exe. For example when I do this:
...
system("mspaint.exe");
printf("Hello");
It opens ms paint and does not print the next message until Paint is closed. How do I work around this?
I am trying to display a messagebox, but instead of just displaying the message box, there is also a console the pops up. How do I prevent the console from popping up? I'm using Visual Studio 2012. I'm creating an empty project, but I still get the console.
View 1 Replies View RelatedMy program is designed to take a reading from a glucometer and light an LED if the reading is too high or too low. I used this code:
#include <eHealth.h>
void setup(){
pinMode(13, OUTPUT); //first alert
pinMode(12, OUTPUT); //green LED
[Code]....
The glucometer stores the tests and the code just pulls the most recent one, however even if I unplug the glucometer the first if statement keeps repeating and the LED in pin 12 keeps shining. Is it the if statement itself malfunctioning, or is the Arduino storing the data it pulled and just repeatedly plugging that into the if loop?
double number = 10000000;
int range;//the length of the string result
string result;//holds the number in a string
ostringstream convert; //stream used for the conversion
convert << number;
result = convert.str();
range = result.length();
I'm trying to convert a double to a string and when the number goes to ten million it goes to scientific notation and it shows it in the string. How do I stop it from do that?
Code:
#include <stdio.h>
#include <stdlib.h>
/*
You are to write a program that will allow a user to enter infinite numbers (greater than zero)(One number at a time). You must have a way for the user to stop entering values.Once the user stops, you will immediately display the following:
The lowest number entered is:
The highest number entered is:
The number of values entered is:
The average of the numbers entered is:
*/
main() {
int userNumber=0, sum=0, count=0, highNum=0, lowNum=0, lastNum = 0;
double average;
printf("Enter a number greater than 0: (Enter -1 to stop)
");
scanf_s("%i", &userNumber);
[Code]....
My program outputs everything I need except the lowest number entered. I have been spending a considerable amount of time on this problem to no avail.
If I wanted to add an emergency stop to an elevator programme should I use an if statement? Eg
Code:
If (emergency stop) {
Void main();
}
Or something along those lines?
This is a problem I have been having with every program I write since I started using SDL 2. Whenever I compile my code and run my program, everything works perfectly fine until at some point (usually after 3-8 minutes of running), the program will stop responding completely and I will have to exit out of the console to close it. The code I believe is relevant is:
void MainLoop()
{
InitLoop();
while ( !QuitMain )
[Code].....
If I change SDL_PollEvent(&Event) to SDL_WaitEventTimeout(&Event,100), then the problem goes away (I did that and had the program running for about an hour without it stop responding before I decided that it solved the problem), so I believe that the problem has something to do with event handling. Also, it might be noteworthy to mention that when I use SDL_WaitEventTimeout with the second parameter being a small number (because 100 milliseconds is a long time to wait and makes the program run at like 8 FPS), the problem returns.
My program has a goto label in it and when the program is not instructed to goto the label, it does. When control goes to the line that it is on, even if no where does it say to execute the label's content, it does execute it.

When my program is working with a big list, it always connects to the internet and checks information from a website. It is going fast, but when I'm trying to update a label on every connection, it just shows at the end, when everything is checked. Progressbar value is updating. How to solve this?

It's a tic-tac-toe program. I haven't finished doing everything I need to for the project, I'm just trying to get certain parts working as I go.
Anyway, my problem: The program will print the board and ask the first player which square they want to mark. Then it will print the updated board, print the question for the second player to input their square choice but not actually stop to let the user enter anything. Instead it prints the board again and then prints the question for player one again -- this time stopping to let them type in their choice.
Here's my code:
#include <stdio.h>
// Function prototypes
void printBoard(char board[3][3]);
int main() {
int quit = 0;
// Loop so game continues until player quits
[Code] .....
And it looks like this when I run it, as an example:
-------------
| 1 | 2 | 3 |
-------------
| 4 | 5 | 6 |
-------------
