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.

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?

Write a program that computes a running sum of inputs from the user, terminating when the user gives an input value of 0

I would like to understand a function on strings. Below is a code that I took from my teacher where the user inputs a string and prints out the length of the string.
Code:
#include <stdio.h>
#include <string.h>
int main() {
char str[100];
int i = 0;
[Code] ....
Now I understand that it returns the count in "int" so my question is:
Let's say i declared
Code: int count = 0;
at the beginning of the code and then made
Code: count = strlen(str);
why wouldn't i have the same result? Is there a way to do it also?

My program was to allow the user to enter a value as a C string in the form: xxx,xxx,xxx,xxx,xxx.xx, where x can be any digit. Well, so far here is my attempt. I think the question is, would I have to implement a switch statement for the digits, the comma, and the decimal, so that when a user inputs, let say 52,000.00 the switch statements would read the 1st digit, checks for decimals/commas and if not, proceed to read 2nd digit, and repeat?

I am trying to get the cin.get working where the user is allowed to enter an 80 character string and how to do that.
I am new to C++ and wrote some code here that is not working how I want it to:
Code:
int main() {
vector<string> distinct;
string parag;
typedef vector<string>::size_type vec_sz;
vec_sz size = distinct.size();
[Code] ....
Basically, if I run it, it takes a string, stores it in a vector string, and then outputs it to the screen as I hit enter. But then it waits for another string to be entered. How can I stop it waiting for new input after I hit enter? I tried comparing parag with and terminating there, but I am getting compiler error. I am using code::blocks.
creating a program using while that terminates the loop when two intergers any two between 1 to 100 are equal with each other
View 2 Replies View RelatedMy assignment is : Please use C type strings ( array representation of strings). Write a program that will ask the user to enter a string. It will then regard that string as a worked-on string and allow the user to perform the following editing functions on it:
s – search
i – insert
a – append
d – delete
a – append
d – delete
r – replace
e – exit
s – search
This option will allow the user to search for a specified string in the worked-on string. If the string is
found, it will display the starting index (position) of the searched string in the worked-on string.
here is what i have so far.

I have a thread with a while(1) loop in it. When the user push the stop button I would like that thread to end.
I thought about creating a bool and checking its value periodically in the thread and when I push the stop button I change the value of the bool for that the thread breaks out of the loop and finishes.
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?

I am having trouble returning use input from iterations after the first series of input from the user. My readCourseArray function can only have one parameter and it is information from the structure Student. This information is gathered from a function which is not in the code below because it works fine. I have hard coded a few lines to try to figure out why I am not getting any input after the first pass of the readCourseArray function. I have tried to delete the tempArray in the function after each pass assuming that that could be the issue. But it was not. At least from what I have gathered. I have tried ignoring new line characters which I never really though was an issue but I tried anyways.
I guess what I am asking is: Is my problem coming from the function itself or from my assignment of the cArray to the return tempArray values?
Like I said, the first pass will print out all of the user input (if I put the code in) but all others will return bad values. I did have a do/while to print out the values but it caused the program to crash. I assume because it hit a bad value and needed to break.

Modify your code by adding your own tests to see if your functions work right. Include at least 6 separate tests, of your choosing.
For example, test the compare function with the first parameter as a blank string -- then with the 2nd as a blank -- then both. Test compare with the first string shorter than the second -- then the other way around. Test your copy function with long strings.
I am struggling with how to use the compare function with a parameter as a blank string. I tried leaving the first parameter blank but doing ("",text) but I don't think that is the correct way of doing this.

I 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.

#include<stdio.h>
int add(int b, int a);

I 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.
