C/C++ :: User Input Returning As Blank When Using Array Of Structures

Feb 14, 2014

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.

#include <iostream>
#include <string>
using namespace std;
struct Student {
string firstName, lastName, aNumber;
int numberCourses;
double GPA;

C++ :: Incorporate Array Of Structures To Read User Input Then Reprint That Information To Screen

Nov 18, 2014

I have to create a program that incorporates an array of structures in order to simply read input from the user and then reprint that information to the screen. This is a fairly simple problem, but the issue is that the professor requires that we solve it in a very specific way.

I must have three functions in total: one to receive input from the user, one to print the received values, and of course the main function which calls the other two. Also, the input and output functions must be defined using the following prototypes:

void inputData(Component C1);
void printData(Component *C1);

Where Component is a structure defined above as:

typedef struct// Component {
float cost;
int code;
char name[30];

[Code] ....

I know that this problem could be easily solved by simply passing the entire 'comp' array to the inputData function, or passing a pointer to it, or having it return a pointer, but I am not allowed to do any of these things. I must use the function as defined by the prototype.

C++ :: Keep Looping Until User Enters A Blank Line?

Aug 4, 2013

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?

C# :: User Control Being Blank On Main Window

This is a tutorial that I have gone through completely with success, but now I am trying to create a different project using the same sort of setup.

When I add my usercontrol to the MainWindow it has none of the buttons/TextBlocks on which I have put on the UserControls - It is just a blank box. What could be causing this?

I have changed the name of the project to [snip] because it has a company name in it...

"NumericControl.xaml"

C++ :: Sorting A User Input For Array?

int main() {
int size;
int list[80];
bool isSorted (const int list[], int size);

C++ :: User Input Loaded Into Array Of Elements

Mar 19, 2014

I am compiling using Microsoft Visual C++ and I am trying to create a program that ask's the user for 10 numbers, and these numbers will have to be loaded into a one dimensional array of 10 elements. I read up online as well as my book and looked at sample programs, then created mine which was similar to the sample programs I looked at, but the sample ones compile , while I get C2059 and C2061 Syntax Errors. I am new to programming so I understand it could be one small thing but I after looking over it I am completely clueless.

Heres my program:

Code:
#include

C :: User Input Variable To Global Array

Oct 11, 2013

I am trying to create a global array with user-defined dimensions.the code is:

Code:

int matr_size()
{
int x = 0;
printf("Please enter the number of nodes: ");
scanf( "%d", &x);
printf("There are %d nodes in this simulation.", x);
getchar();
return x;
}

[code]....

I read that an array cannot be defined by a variable in C so I assume that is the issue, but I'm not sure how else to do it. Previously the size was defined by #define NODES and it worked fine but I need this user input.

C++ :: String Array - Sorting User Input

Oct 25, 2013

I have been reading up on arrays and string array. I created a string string text[0] and it is defined by user input. I am trying to sort the input. I want Michael to read Macehil.

When I wasn't using an array and just a string I did this:

return sort(text.begin(), text.end()); a

And it worked fine. Do I need to change my string into a char? If so, would I static cast that?

C++ :: Char Array Size - Undefined Until User Input

Apr 27, 2014

So I'm trying to make a program, Which has nothing to do with the topic. But I ran into a problem.

I need to get a char array size of 6 doing:

char myChar[6];

but the size (6) is undefined until user input.

So I need to do char myChar[var]; (Var being 6 for now).

When I do:
char myChar[6];
It works!!!

But when I do:
int val = 6;
char myChar[val];
It doesn't work.

C++ :: Take User Input Selection Of Columns And Determine Array

Aug 29, 2013

I am writing code for a program that will take user input selection of columns and determine an array based on that.The number of columns will be user selected.The number of rows equals 3^(columns) <--exponent not XOR

- This is because each column has the possibility of having the numbers 0,1,or 2

For example, if the user were to select "4" columns, then the array would have 4 columns and 3^4=81 rows. Then I would like to populate this with all of the possible combinations of 0,1,2

i.e.
0000
0001
0002
0010
0011
0012
0020
0021
0022
0100
....
2220
2221
2222

how I would create the "For" Loop for this?

C++ :: Store User Input Then Display Array Contents?

I'm coding a hangman game. I'm trying to store user entries so i can output them to show the user what they have already entered. Problem is that it's not display anything at all.

I'm trying to store multiple characters of course, and then display all characters stored.

char guess[27]={0};
cin >> guess[26];
int hit=0;
for(int i=0; i<len; i++) {
if( guess[26] == hidden_word[i] ) {
hit++;
select_word[i] = guess[26];
if(strcmp(hidden_word,select_word) == 0) {

[code]....

EDIT: I also get the error - Stack around the variable 'guess' was corrupted. At the end of the game.

C++ :: Build Array Of A Size After Receiving User Input

Sep 25, 2013

I'm trying to build an array of a certain size, after receiving user input. The method I'm trying is

int var = 3;
int* ar = new int[var];

When doing tests I did this (and it worked) and red flags popped off in my head.

int var = 3;
int* ar = new int[var];
ar[0] = 0;
ar[1] = 1;
ar[2] = 2;
ar[3] = 3;
ar[4] = 4;
cout << ar[0] << ar[1] << ar[2] << ar[3] << ar[4] << endl;

This method is considered safe, and possibly tell me why I'm not getting stack errors when trying to overload the array?

C++ :: Validating User Input - How To Declare Array Of Character

Apr 29, 2012

Question simple like that: Let user enter some words from keyboard, one word per line until a '.' (period) entered then print out result, for example:

Code:
Enter a word: word1
Enter a word: word2
Enter a word: .
You have entered 2 word(s):
word1
word2

Problem is I don't know how to declare the array of character at the beginning since I don't know neither how many word user may enter nor how many letter of each word. So I go ahead and declared like this: char word[20][50] but I know it is not best way.

Code:

int main () {
char word[20][50]; //array has maximum 20 words, each word maximum 50 character
int i=0, number_of_word;
do {
printf ("Enter a word: ");

[Code] ....
