C++ :: Trying To Get User Input Into Array
Apr 25, 2014
I have written a program and i had to pass an array into a function and now i have a variable for the subscript of the array and i was the user to input data, specificlly a string, more specifically first and last name without having to create two arrays, i have to do this with other things in the program as well, here is part of the program:
int addFunc(const int totNum, string city[],string state[],string street[],string name[],
int addNum[],int zip[],int telNum[],double bal[],int dateLp[], int addCount, int accNum, int usNum)//function will add a new account {
int countAf = 1;
if (usNum < 20)
[Code] ....
it should be able to take firstname space lastname

I am making program that allows the user to determine how big the array size will be and then asks the user to make up numbers to fill the array. Every time run the program on Dev C++ it says "program has stopped working"
Heres My Code:
//Assignment 19 Program 2
#include <iostream>
using namespace std;
int main()

My parameters are that the users input has to be from 1 to 9 and the same number can't be entered twice. How do i modify this code to make sure that the user did those things or an error message should appear that their input is invalid.
#include <iostream>
using namespace std;
int main() {
int square[3][3];
[Code] ......

Say you the user inputs x number of names and then is to put in x amount of values for each name. How would you display these values in a 2d array and be able to add the values for each row which will represent each name?

Were supposed to be able to sort an array which is user input, but the first number they input is supposed to be the length of the array, and everything after that is the actual array.
Here is my code:
#include <iostream>
#include <iomanip>
using namespace std;
int main() {
int size;
int list[80];
bool isSorted (const int list[], int size);
[code]....
I'm stuck on how I'm supposed to use the first digit of input for the array size.

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
<iostream>
int
main()
[Code] .....
My program is also attached

If the user puts in a 6. I need the array to display the even number from 0 - 6. Right now what it does is it displays the first six even numbers. Okay as I'm writing this I'm starting to see where my problem might be..
Code:
void sumIntegers () {
int arr[50];
int i = 0;
int num = 0;
int sum = 0;

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.

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?

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.

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?

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.

How would you search in a vector array from a user input string?
ex: user input : "Hello"
output: search vector array and find the line that has the string "Hello" and output the array "Hello" is on?

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;
[Code] .....

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?

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: ");

i was trying to solve a problem in SPOJ and what i wanted to do is to accept an input number from the user and to convert it into a array of integer.
Code:
#include<stdio.h>
int * toarray(int *num);
int main(void)
{
int testCases;
}
[code]....
But whenever i try to print the array in the main function i get only two value and the rest address
Code:
1//number of testCases
23456 //input number
6
2293452
4
2293700
1974439125
Process returned 0 (0x0) execution time : 4.152 s
Press any key to continue. However, if i tried to print the array from within the function, it prints the numbers just fine.
print the array elements from the main program, so that i would be able to go on with the rest of it

I'm trying to make a c++ program of this but i don't know how to use the bubble sorting.
Write a C++ application that asks the user to enter 10 numbers. The program then stores those numbers in an Array. The program should display the Mean , Median, and Mode.
Mean is the average of the 10 numbers.
Median is the average of the 5th and the 6th numbers. (But you have to arrange the numbers in ascending order first using Bubble Sort before calculating the Median.)
Mode is the most frequent number among the 10 numbers.

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.

In this simple end-of-chapter problem, the ages of two people are to be compared and determine who's older. The problem I'm experiencing is that the second user name input is being skipped and going straight to the second users age.
So while running the program it looks something like:
What is user ones name?
<input name>
How old are they?
<input age>
What is user twos name?
How old are they?
<input age>
<if statement result>
Here's my code:
Code: #include <iostream>
#include <string>
using namespace std;
int user_one_age;
int user_two_age;
string user_one_name;
string user_two_name;
[code].....
