C++ :: Program Skips Over User Input?
Dec 6, 2014
I am so close to finishing this program of games, but I'm running into some issues while debugging it.
I've attached the google drive folder since there are several files (ignore the ones with [conflict], etc)...
First, I have the main menu using a switch to select the game. The default was set to exit. If initially when immediately opening the program you put in for say, a letter, it would exit like its supposed to. But if you went and played any of the games ], went back to the main screen, and entered a letter then, it would crash. I've put in a testing line to make sure that you enter a number, and not anything else.
Now however, if you play a game and then want to go back to the main menu, it will simply skip over waiting for your response and close the program. The same thing happens in the slot machine, I want to have it spin the slot machine by pressing enter, but it simply skips over the input, and I'm not sure why.

I just recently finished up a program that implements Dijkstra's Algorithm and I thought I would make a nice little menu for the user.
so the user can input their locations, I use Getline just in case their location contains spaces. However, when the user selects 2, It skips over the first input for the "Source" location and only lets the user input for the "Destination".
Any reason why this would happen? Am I missing something with Getline? Anyway, here's the code...
template <typename V, typename E>
void Graph<V, E>::Driver() {
bool done = false;
int menu(0);
InputFile();

I don't understand why my Do While loop skips over the input the second time round?
#include <iostream>
#include <cstring>
#include <cstdlib>
#include <string>
using namespace std;
//prototype
string reverseInput(string *);

I am altering this program to include some alterations for a class. When I run it with start without debugging, it just skips to press any key to continue. It will not display the cout << "Volume of box1 = " <<boxVolume1.
#include "stdafx.h"
#include <iostream>
using std::cout;
using std::endl;
class CBox {
public:
double m_Length;
double m_Width;

I need the program to do a calculation after the user inputs 10 numbers . This is what I have tried so far:
int count;
float value, high,low, sum,average;
sum=0;
count=0;
input:
printf("Enter a number (enter negative value to finish program):
");
scanf_s("%f",&value);
[Code] ....
output:
average=sum/count;
if(count==10) {
printf("total values :%d
",count);
printf("The Highest value :%f
Lowest Value: %f
",high,low);
printf("The average of the values is:%f
",average);
}

I built a program that accepts two input from the user, using a array inside a loop, it is pass to a function inside a class which will display the two number, the problem is when the user is inputting a number and it is 1 the program continuously as the user to input a number, and when 2 is entered the program ask another number and end, but for example you entered 2 and 3. . . it will then outpu 2 and 4 (so 3 + 1 ) and always the last number is plus one. here is the code.
main.cpp
#include <iostream>
#include "newclass.h"
using namespace std;

So we have a weekend assignment that is "Write a c++ program that will allow a user to input their first name into a string, and use the switch/case statement to produce the following output. Your Program should prompt the use rwith the numbers and the options for each (school, classification, and mood) allowing them to make a choice"
My issue is with the output. The output at the end is the number that they input and not the name of the case they chose, so if they chose option 1 for school it does not print out "BRCC" at the end for the output it prints a 1.
#include <iostream>
#include <string>
using namespace std;
int main(void) {
string name;
cout << "Please enter your name: ";
cin >> name;

I need a program to run that will accept an input for user id. It will take the customer input and capitalize the letters, and return invalid id with the user inputted values. Then if it's valid it will add a counter counting the number of letters and numbers. It will keep track until the user puts in !. It seems when I try to pass values from the array to my toUpper function to capitalize it it doesn't seem to work right.

I need to create a command where the user inputs a character and it'll exit out the program rather than executing any of the other code.
For example :
If I wanted to do like
char key;
if (key == D || key == d)
{
}
What would I need to put in between those brackets under the if statement to allow the user to enter the letter D and it would close out the program?

I'm trying to write a program that capitalizes every other word of a user output. (ex: if input is "i love you", the output is "i LoVe YoU").
I am using a for loop (although an if loop might be easier?) and I'm assuming that it is possible to write this program using a for loop (although I may be wrong--maybe only if loops can write this program). I have everything down EXCEPT the last step where I have to print the entire sequence. What i have so far is:
Code:
#include <cs50.h>
#include <stdio.h>
#include <string.h>
{
// get user input
printf("Type a sentence: ");
string s = GetString();
[Code] .....
The code above basically only prints out the capital letter (ex: input is "hello", output is "EL"). I don't know how to print out the entire sequence.

// clang++ -g -std=c++11 main.cpp -pthread
#include <iostream>
#include <thread>
#include <unistd.h>
void thread1(void) {
while(1)
[code]....
Thread 1 does some background work, and thread2 is waiting for the user's input. If I join thread1 then the app can never exit. If I neither join nor detach thread1 then I get "terminate called without an active exception Aborted" which is not a good thing to have. If I do detach on thread1 does thread1 ever terminate? If not, how to terminate it? Also, how do I check if it's terminated or not?

I need to create a program that will prompt the user for an input, then it will save their input to a file and then it will prompt the user to input "Open" and then the file containing their first input, will open up and show their input.

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 |
-------------
| 7 | 8 | 9 |
-------------
Player 'C' enter a square: 5
-------------
| 1 | 2 | 3 |
-------------
| 4 | C | 6 |
-------------
| 7 | 8 | 9 |
-------------
Player 'U' enter a square:
-------------
| 1 | 2 | 3 |
-------------
| 4 | C | 6 |
-------------
| 7 | 8 | 9 |
-------------
Player 'C' enter a square:

I have an a problem I need to make lottery random generation program what asks from user how many lines to gerenate random numbers. But i am now stuck.
Console.WriteLine(" choose how many numbers ");
int i = int.Parse(Console.ReadLine());
Random randomizer = new Random();
for(int j = 0; j < 7; j++) {
i = randomizer.Next(1, 39);
}
Console.WriteLine("Your random numbers are{0}", i);
Console.ReadLine();

#include <iostream>
#include <string>
#include <limits> //for std: numeric limits
#include <algorithm>
//Function to get an integer from the user that is greater than or equal to zero.
int getPositiveIntFromUser(const std::string& prompt) {
int retVal = -1;
[Code] ....
The first part works, but it doesn't calculate the GCD or LCM at all, it just crashes!

Code:
// clang++ -g -std=c++11 main.cpp -pthread
#include <iostream>
#include <thread>
#include <unistd.h>
void thread1(void) {
while(1) {
int i = 88 * 2;
[Code]...
Thread1 does some background work, and thread2 is waiting for the user's input.
If I join thread1 then the app can never exit. If I neither join nor detach thread1 then I get "terminate called without an active exception Aborted" which is not a good thing to have.
If I do detach on thread1 does thread1 ever terminate?
If not, how to terminate it?
Also, how do I check if it's terminated or not? -- I realize it's platform specific, I am on Linux.

My program works primarily by receiving user input however; using 'char' and 'fgets' i have to stipulate how many characters i want assigned, and this isn't practical for what I am after. Example below.
Code:
char example[50];
printf("What colour is the sky?
");
fgets(example, 50, stdin); Is it possible that the assigned number (in this case '50') is determined strictly by the user input?
for example, user input is Blue then 50 is then 5?

This program will allow the user to input string then scans the file if it contains the same string given by the user. But i always get "MATCHED" even if i enter random string. I tried and tried to place the if statement in different positions but i dont get my expected output.
Code:
#include<stdio.h>#include<stdlib.h>
#include<time.h>
#include<string.h>
int main() {
int found;

I need to write a program to make the user input some text, and the first letter of each word has to be uppercase. (have to use while loops)
So for example lets say the user inputs:
i lOvE pRoGrAmMiNg
The output needs to be:
I Love Programming
Code: int main()
{
char c, lower_c;
printf("Enter Text");
while (c != '' && c >= 0)
{
if (c >= 'A' && c <= 'Z')
lower_c = c + 32;
else
lower_c = c;
[Code]...
I have started this code by making the letters lowercase (I don't know if this was the right way to approach this, ). I am not sure how proceed after this step, the step of making the first letter uppercase. (PS for the program, loops should be while loops)

So I am writing a program that counts the letters of 3 lines of input from the user. I am using a 3 x 80 character array as the "notepad". Upper and lower case characters are incremented on the same counter array.
Code:
/*Letters in a string*/
#include <stdio.h>
#include <string.h>
#include <ctype.h>
void countAlphabet(char *);
/*Character counting array*/
int alphabet[26] = {0};

Figure this out using [TURBO C]
Create a program that will let the user input an amount in the form (367). The Program should determine the no. of coins for each dominations : 50,25,10,5,1. (using Turbo C)

I am writing a C++ program which takes date & time input from the user. This is then parsed into a struct such as:
struct time
{
short year;
short month;
short day;
short hour;
short min;
};
My question is: how can I convert such a struct into a time_t object, which is an unsigned long giving the time as the number of seconds elapsed since the epoch Jan 1st 1970, 00:00, as set out in time.h.
I am wondering if this can be achieved using the standard library, or whether I just need to write a function to perform the appropriate arithmetic.

The problem that I am having is that , the program outputs numbers that are perfect numbers and im not sure where i can add a statement to make it so that if it isn't a perfect number it doesn't output...
#include<iostream>// allows user input/output
#include<conio.h>
#include<fstream>//data file / result file
#include<iomanip>
#include<cmath> // math function
#define in_file "data.txt"
#define out_file "result.txt"

I tried to work on this program for while, but I am not able to get it to work
Directions:Write a program that reads an integer n from the user.
Display the first 100 numbers, with newlines every n numbers, using % operator
#include <stdio.h>
int main(void){
int a = 0;
int b = 99;
printf("Enter a number: ");
scanf ("%d", &a);
[Code] ....
When I run this code it asks me to enter a number. It doesn't matter what number I enter it gives me the numbers from 1 to 100 in one horizontal line.
I want this program to do something like this:
for example if the user enters n=6 the program should give:
0 1 2 3 4 5 6
7 8 9 10 11 12 13
and so on
