C++ :: User Press Space To See Next Line Of Output?
Jun 10, 2013
I have been trying to make a small program that I will be using in a larger program that will make the user press space to see the next line of output.
Not exactly sure what I'm doing wrong, but I'm pretty sure that I need to put the space that the user would enter into an output file, and the read the input file
It runs, but it doesn't allow me press space before showing the next line.
I added a getline(cin, charVar) before, but I got a whole bunch of errors.
#include <iostream>
#include <string>
#include <cctype>
#include <cstdlib>
#include <fstream>
using namespace std;
// function for dialouge
[Code] ....

My program closes after the out even though i've used cin.get():
I want the program to stay open at least until you press enter, even after the whole output.
Code:
#include <iostream>#include <string>
int main()
{
std::cout << "Please enter your name";
std::string name;
std::cin>> name;
// build the message that we intend to write

When the user gives no input, they have to press enter twice before "Done." is printed.
cout << "What do you want the name of your page to be? ";
std::getline(cin, pageTitle);
if (cin.get() == '
')
pageTitle = "Welcome to Website.";
cout << "Done.
";
Is there a way to print "Done." after pressing enter once?

When i set any 3 inputs length, the space should be move in right position. I try to fix the space move forward into 1 space, but don't know why it doesn't work. Specially, when the number is 4 or 5. The space didn't move 1 space.
using System;
class length{
static void Main(){
int i,j,k;
string star = "*";
string s1 ="";
string s2;
int[] nums = new int[] {3,4,5};

I trying to get input from the user and split into words that separated by a space.
string s = "1 2 3";
istringstream iss(s);
int n;
while (iss >> n) {
cout << "* " << n << endl;
}
The code above works fine but i want to get the string from user. the code below only prints the first word and trashes rest of the words in the sentence.
string s ;
cin>>s;
istringstream iss(s);
string n;
while (iss >> n) {
cout << "* " << n << endl;
}

I'm not too sure why I'm missing a line from the output. I've been going over my code like crazy and something seems to cause a line which would be size = 0: [nothing here] missing in my output. Here's my code:
Code: class binSTree: public binTree<T>{
public:
void insert(const T& x); //insert node with value x
bool search(const T& x); //searches leaf with value x
[Code].....
Other files are included but they are 100% correct as I used them in my past couple of assignments. The public version of remove is suppose to call the search function and determine the result of the search for a leaf with value x. Calls private remove and returns true. Otherwise it returns false if the search isn't successful.

void printList(int list[],int cnt,int numsPerLine){
for(int i=0;i<cnt;i++){
cout<<list[i]<<" ";
if((i%numsPerLine)==0)
cout<<"
";
} }
So cnt is 20, numsPerLine is 10, and list[] is initialized with a const = 20
i%numsPerLine on the first loop equals 0 and thus outputs a new line.
I'd like it to new line after 10.

Taken from Accelerated C++ book, I modified those code to use getline() instead of std::cin >> only to find out that the output has extra line. Why is that so?
#include <iostream>
#include <string>
int main() {
std::cout << "What is your name?" << std::endl;
std::string name;
[Code] .....
What is your name?

I'm trying to get this programme to work but I can't get it to output the string data at the end of the line.I have copied and pasted the line in question below but it may be a prob with the prog further down.
It reads character input ok but doesn't put one string into another or recognize when a string is quoted in a printf.
Code:
printf("%s what is your second name?
", surname, name2, name);
#include <stdio.h>
int main ()
{
char name[20];
[Code] ....

I am having an issue with the statement "Both the input and output files' names should be read from the command line." I don't understand what this means or what I need to do.

int get_command_line (char * sa) {
char * s;
char * l = fgets(s, 300*5, stdin);
int i = 0;
int j;
int n;

The aim is to have the function return the number of arguments made after assigning each of the arguments to a c string stored in an array of five pointers. This is how I declare this:
int main(void)
int n;
char s0[300];
char s1[300];
char s2[300];

My goal is to create a loop that keeps taking user input over and over until the user doesn't enter anything into 'cin >>', leaves the line blank, and simply presses the ENTER key to move on, at which point the program is supposed to break out of the loop and continue on with the rest of program execution. Something like this:
Code:
do {
cout << "
Enter a name: ";
cin >> input1;
if (input1.empty())
[Code] ....
As you can see, I've already tried using the empty() function, but that didn't work, the program simply stays in the loop and doesn't break out, no matter how many times I press enter. It just keeps prompting me to enter a name. I've also tried using something like
Code: if (input1 == "")
but that doesnt work either. How do I break out of this loop?

My program allow user to draw lines and the user should know the length of the line that he draw in centimeter (.cm)
I did use
SetMapMode(MM_LOMETRIC) function to convert the device units into logical units
and it works correctly but I don't know how the line length will appear to the user to let him draw in correct length
I think to make the length appear on the mouse when the user draw but I don't know how I calculate and display it.

I want to be able to write a program where I can record user input but combine it with command line arguments. For example I do a simple getline(); and the user types test how to combine it so it could be like test /q and it gives a different output depending on what additional input was added. Can this be done with lots of different inputs?

How can I create in my C++ program so a user can paste a text and then choose a character on specific line and place?. The above thing isn't that important. I just want to place a character on a specific line and place.
I mean something like this:
Enter a character:
You choosed " / "
On which line do want the character?
You choosed "Line 1 and 2"
Where do you want the the to appear on the line? (left or right)
You choose left.
Results:
Line 1. / hello
Line 2. / hello

How to get this thing to work. All i need to do is ask user to input a name and then it brings out the line from the .txt file containing the information.
For example in my case I'm doing a member search function I'm required to ask user to input the name of the customer and then print out all the details (which consumes 1 text line in the .txt file)
Here is the code, This is the write to text file method (100% working)
Code:
cout << "Customer Name: ";
cin >> name;
// ...
ofstream myfile("customer.txt", ios::app);

I'm trying to write a program that takes input from the user (thats a char) and outputs it to the monitor in hex form.The program is meant to continuously take input from the user then output to the monitor in hex form until an EOF is detected this triggers the program to close.The following code does this except that I get a lower case 'a' at the end of each output.I think the 'a' has to do with the enter key and if that is the case how can i tell the program to ignore this input from the user.
Example: input from user: ABC output to monitor: 41 42 43 a
Code:
#include <stdio.h>
int main(void) {
char myChar;
while(EOF != (myChar = getchar())) {
printf("%x ",myChar);
}
system("pause");
return 0;
}

I am writing a code in a class that will change the user input which is integer to a string. For example if the user enter 13347..the output should change to "one three three four seven" on the user screen.I'm not getting the right output.
Code below:
#include <iostream>
#include <string>
using namespace std;
string arr[]={"one","two","three","four","five","six","seven","eight","nine"};
class convertTo{
public:
int signed num;
int convet(){
cout<<"Enter a number to convert to string "; cin>>num;

I created a C program that extracts some information from computer and displays it on screen. It is completed today and is going to be applied to startup programs of domain machines. It runs at logon and takes somewhat 5-10 seconds to finish execution. The output is shown on console screen & user can either close the window by clicking on 'x' or pressing 'Ctrl+c' during execution. How do i prevent both of these events?
Basically the most time consuming processes are
Code: popen("systeminfo","r");
popen("wmic qfe get installedon","r");
1st command is getting OS name,version and hotfixes installed.
2nd command gives me the date of updates installed.
I then filter out data & print required information only.
