C++ :: Data Input From Txt
Nov 27, 2012
I have this code.
Code:
#include <string>
#include <iostream>
#include <fstream>
#include <math.h>
#include <sstream>
string scoresort[9];
int HighScore(int PlayerScore){
[Code] ....
Now I can't put data into the array scoresort[x]. I have tried everything. When the scoresort[x] is not an array I can input data. Although when it is an array it crashes my program. It will not process the line.
This is part of the HighScore section for a game that I am currently making.

I want to input data into text file while not deleting the original data in the file and I use something as
ofstream writefile;
writefile.open("example1.txt");
if (writefile.is_open()) {
for(j=0; j<N; j++) {
[Code] ....
But this will delete the original data.

I am trying to write my files to another subfolder . Below is my program.
Code:
cat th6.c
#include <pthread.h>
#include <stdio.h>
#include <string.h>
#define SIZE 8
#define NUMELM 8

I know that an int is usually 4 bytes, ranging from -2^31 to 2^31-1 for a signed int and 0 to 2^32-1 for an unsigned int. My question is simply, bit-wise (I know they are labelled in the code), how does it determine whether to show -2^31 or 2^32-1 if it was 11111111 11111111 11111111 11111111 in bits? Is there a 5th byte to tell the compiler what data type to treat the input as?

i'm making a for loop for a mini game which required the user to enter the input number.Let say if the user accidently entered a character instead of integer the whole program will go haywire so is there anyway to check for the error and prompt the user to input the data again?Here is the simple program...
for(row=0;row<4;row++)
{
printf("Enter Row%d:",row);
for(col=0;col<4;col++)
{
scanf("%d",&num[row][col]);
}

I'm currently trying to solve a programming assignment and i got the logic of it, however i find it hard to implement.
What i need to do basically is fill an array with objects. Each object is a class that contains only one type of data. This means i can place int, double and string for example in one simple array.
However i can't figure out how to read data and then decide what it is. Even if i use templates once i call the function i have to give it a type, so getType<int> for example will not work with double or string.
I know about typeID and how to use it, i just can't figure out where to use it.

Modifying this program to Create a function that has the following prototype: void getInputChar(string, char &);.
The function should display the string on the screen and then use cin to read a char from the keyboard.
#include <iostream>
using namespace std;
bool ignoreCaseCompare (char, char);

Ben has been administering a MBTI personality test. Now he has all the responses, but the task of scoring and compiling results seems daunting. The personality test* is a series of 70 questions for which the available responses are ‘A’ and ‘B’. Based upon the answers to the 70 questions, a personality profile is determined, categorizing the degree to which the responses place the person on four scales:
Extrovert vs. Introvert (E/I)
Sensation vs. iNtuition (S/N)
Thinking vs. Feeling (T/F)
Judging vs. Perceiving (J/P).
Each of the 70 questions relates to one of the four scales, with an ‘A’ response indicating the first of the corresponding pair (E, S, T, or J) and a ‘B’ indicating the second (I, N, F, or P). For instance, an ‘A’ response on the question: At a party do you:
A. Interact with many, including strangers
B. Interact with a few, known to you indicates an Extrovert rather than an Introvert; just the opposite for a ‘B’.
For this test, each question is designed to influence one of the four scales as follows:
questions 1, 8, 15, 22, 29 … are used to determine E/I,
questions 2, 9, 16, 23, 30 … and 3, 10, 17, 24, 31 … to determine S/N,
questions 4, 11, 18, 25, 32 … and 5, 12, 19, 26, 33 … to determine T/F, and
questions 6, 13, 20, 27, 34 … and 7, 14, 21, 28, 35 … to determine J/P.
Notice these come in sequences of “every 7th” question.
The goal of the test is to determine which end of each of the four scales a person leans, and to thus classify him/her based on those leanings (e.g., as ENFJ, INTJ, etc.). Since Ben would also like an indication of how strongly the test taker fell into each of the four, the program should print the percentage of ‘A’ responses for that scale.
Input for this program should come from a file responses.txt. The first line of the file will contain a single integer, n, indicating the number of test results to follow. Each of the following n lines will contain the first name of the test taker, a single blank, his/her last name, a single blank, then the 70 responses he/she gave on the test. Although the test instructions indicate that the results are most valid when all questions are answered, sometimes respondents leave questions blank. In that case, a dash appears at the corresponding place in the list of responses.
Output for the program should be written to the file types.txt. It should include a well-formatted report listing, for each test taker, his/her name, the percentage of ‘A’ responses in each scale, and the resulting personality type. A tie within a scale should result in a dash (‘-‘) for that part of the personality type.

How would I check for proper data type when someone is to input a value into the program? Ex:
int i;
string a;
cout << "Enter a number: ";
cin >> i;
cout >> "Enter a string: ";
cin >> a;
How would you check to make sure that int i would be an actual number and not a letter like "a"?

I want to have input data stored in a database. All information entered is to be stored under a single block. That way whenever I want to recover that information all I have to do is point to that block. Think of it like this. I want a large square block that can hold certain information. Inside of that large block are a finite amount of smaller blocks in which the user entered information about a single subject. Lets say block 1 has a name, address, and phone number. The second block will have the same TYPE of information, but different values as entered by the user. I.E:
BLOCK 1: Name 1, Address 1, Phone 1
BLOCK 2: Name 2, Address 2, Phone 2
etc.
The large block contains all of the smaller blocks, we will name the large block "Address Book" ... How would I implement that? Of course it would be just a simple console program that would erase all information when the program shut down, but I've been trying to figure out how to do it, but just can't seem to grasp a good notion of how to do it. What would be the best way to do that? Structures? How would I make it dynamic so that I wouldn't have to define every block, so that it would be added on the fly when someone inputs new information.

how to stop outputting data based on a user input. The text file is as follows:
1. a
2. b
3. c
and the code I'm using is as follows:
int main (){
string line;
int search;
cout << "Enter a number from 1-3" << endl;
cin >> search;
search++;
ifstream myfile ("example.txt");
[Code]...
What I want to do is to just output number 1 (the whole line) if the user enters number 1. However, I get an error on the second condition w/c is the "&& line!= search"

I'm having issues trying to input data from a .txt file into my array program. The whole program takes the name, # of goals and assists, adds them together to get points, and then puts in a given + or - rating. The program works except for the data input.
Also, this is an alphabetical "Unsorted" list, but is there a way to order the list based on point value and be able to display that as well as a separate "Ordered" list?
#include <iostream>
#include <iomanip>
#include <fstream>
#define NUM_PLAY 30
using namespace std;
int buildArrays(int[], int[], int[]);
void printArrays(string[], int[], int[], int[], int);
[Code]...
And this is the .txt file. Order is Players Name, Goals, Assists, Plus/Minus rating. The points are added when points = goals + assists (Should be in the main coding above).
Bryan_Bickell 2 5 +2
Brandon_Bollig 0 0 0
Dave_Bolland 4 2 -1
Sheldon_Brookbank 0 0 -1
Daniel_Carcillo 0 1 +3

Here's my code so far:
Code:
#include <iostream>
#include <iomanip>
using namespace std;
int main() {
int dayNumber = 1;
[Code] ....
The code, when run, prompts the user to input an integer like this:
Code:
Day 1
Andy :>12
Bill :>7
Charlie :>15
Day 2
Andy :>5
Bill :>25
Charlie :>14
.
.
.
etc.
Ok, so the code prompts the user to enter an integer for each of the 3 persons and then increments the "Day" and so on... When the user enters a negative value (-1, -2, etc.), the loop is broken and the program ends. Alright, everything is hunky-dory so far. 2 things which I can't figure out.
1. when the user doesn't enter anything and just hits return, the cursor drops a line and is still awaiting an input but doesn't show the prompt "Andy :>", for example. How can I get it to repeat the last prompt when the user doesn't enter anything? Like:
Code:
Day 1
Andy :>
Andy :>
Andy :>12
Bill :>25
Charlie :>15
.
.
etc.
2. When the user enters a letter or a special character, the program blows up. How can I correct this?
I've tried changing the data type for the variable used for the input, tried using getline, get, etc. With my current beginner knowledge, I'm missing something. So how can I get this to work?
The program should allow only integers to be entered, while allowing a negative number to trigger the loop to break or the program to end, and while re-prompting the last person if the user entered an invalid input.

I'm still fairly new to c++ and am having trouble with dynamic arrays. My task is to create an array for test scores. The user needs to define the size of the array and then input data to later sort and calculate the average.
Below is what I have so far. I am struggling with the user input part. I receive the following errors for the data input of the individual scores:
"error C2108:subscript is not of integral type"
"IntelliSense:expression must have integral or unscoped enum type"
Code :
#include<iostream>
#include<iomanip>
using namespace std;
int main() {
//user input total number of scores
cout<<"Please enter the total number of test scores."<<endl<<endl;
