C++ :: Assigning Input To Value - Random Output
Jul 24, 2014
I'm using getline, and stringstream to assign an input to a value. How to do something similar with a random output.
//Battle with Samer
#include <iostream>
#include <string>
#include <sstream>
#include <ctime>
#include <cstdlib>
using namespace std;
const char* PokemonSamer[6] = {
"Charizard", "Umbreon", "Mew", "Arcanine", "Espurr", "Luxaray"
[Code] ....
When I run <PokemonSamer[rand() % 6]>, I want to be able to save whatever that output may be, and save it to <string Samer>. Is this possible?

What I am doing is using fgetc to take a char input from the user, and then directly after that calling a function which will clear the buffer and remove the character. But for some odd reason all my inputs are being assigned before taking the char input by the user. Here is my code for the relative problem:
Code:
char playAgain; Code: playAgain = fgetc(stdin);
readRestOfLine(); Code: void readRestOfLine(void) {
int ch;
/* remove all characters from the buffer */
while(ch = getc(stdin), ch!='
' && ch!=EOF)
;
/* clear the error status of the input pointer */
clearerr(stdin);
}
And en example through terminal of the issue, with print statements debugging the value of play Again:
So in both instances here I have entered 'y', one returning it as ASCII 10 which is ' ' and ASCII 121 which is 'y'.

I will keep this simple as I have the code written for my testing software program, I just want to add a feature of randomly generating the answer choice output order, I do not want to randomly output the full questions, but instead the choices (answers to the question), for example =
#include <string>
#include <iostream>
#include <limits>
cout <<" " << endl ; \ space
[Code] ....
As you can see I would like to output the answers, choices randomly as in answer choice 3 will appear at the top instead of 1. and so on, it doesn't matter if the numbers move with the txt as the numbers beside the
questions are txt.
It's a 32bit console application.

I am constructing a random text generator and i am almost done i just need final output. Here is my coding
#include <iostream>
#include <cstdlib>
#include <ctime>
#include <string>
using namespace std;
const int NUM_FRIENDS = 5;
[Code] ....
This is how the output is supposed to look like
Program Output
== Who Should I Text? ==
Enter seed
Enter friend 0
Enter friend 1
Enter friend 2
Enter friend 3
Enter friend 4
You should text: Cat
These other friends didn't make the cut:
Adam
Bill
Damion
Edward
I can't figure how to output the remaining names.

today I've been working on a rock, paper and scissors game. It compiles OK, except:
It doesn't use a random number from 1 -3, or goes out of scope.2. It doesn't COUT and it doesn't flush the buffer.3.
My code is as follows:
#include <windows.h>
#include <iostream>
#include <cstdlib>
#include <ctime>
std::string randomPC(int &);
void PCSelect(int &);
[code]....

I can't compile this code as I am at work and the computers are security protected, So i''l have to wait until i get home to test this, but I am pretty sure I am wrong. The problem is I have to create two vectors with 10 elements and input random numbers into it, then pick one of the elements of the second vector at random and append it to an element from the first vector at random. This has to be done 10 times and the I am assuming i have to print the 10 results. This is what I have:
#include <cstdlib>
#include <ctime>
#include <iostream>
using namespace std;
int main() {
vector<int> random (10);
[Code] ....

I need my program to read a list of numbers from and input file, random.txt, and calculate the following statistics on those numbers:
A. The number of numbers in the file.
B. The sum of all the numbers in the file.
C. The average of all the numbers in the file.
D. The largest number in the file.
E. The smallest number in the file.
#include <iostream>
#include <fstream>
#include <iomanip>
#include <string>

I would like to, when running cat, send in some data like "testing" to its stdin, and then catch the output of stdout, and put it into a character array variable.Currently the parent stalls till the child is done.I imagine the parent has to some how detect that the child executed 'cat', and then send in input to stdin?Then somehow detect that 'cat' is done executing, and read the output from stdout? I have looked around and found "dup2", but I don't understand how to send in and get data to the child from the parent, especially since the "file descriptors" is not pointing to any files in the first place..

I have a program that needs to output the input with a setprecision of 2 but when it outputs 0, it has to be "0", not "0.00"
How will I go about that?
Here is my code:
void PrintAllSales(double sales[][SLSPRDT]) {
cout << fixed << showpoint << setprecision(2) << endl;
cout << "ALL SALES
";
WriteLine('=', 63);
[Code] .....
And here is how it comes out:
1234
ALL SALES
===============================================================
Product # | 1 | 2 | 3 |
Salesperson 1 | 2000.00 | 0.00 | 299.00 |
Salesperson 2 | 0.00 | 2543.98 | 95.99 |
Salesperson 3 | 0.00 | 0.00 | 19.99 |
Salesperson 4 | 0.00 | 3854.75 | 0.00 |
But it should be like this:
1234
ALL SALES
===============================================================
Product # | 1 | 2 | 3 |
Salesperson 1 | 2000.00 | 0 | 299.00 |
Salesperson 2 | 0 | 2543.98 | 95.99 |
Salesperson 3 | 0 | 0 | 19.99 |
Salesperson 4 | 0 | 3854.75 | 0 |

How to structure the input of one .dat file and outputting into another one. I have to loop through a file structured "doe, john, 1500", check for errors and then increase the mp by 50. You also have to do this through using a person class too. I think I need to use a while loop to go to eof and use getline to input correctly, but im not sure how to structure it.
Data file:
Horowitz,Jake,1200.24
Flabitz,Bubba,1712.38
Blackwell,Sharon,1872.93
Molerat,Rufus,501.00
Goodall,Jane,1567.43

for our school project, we have to make a program which involves three students and the prices each of them paid for the meals. The program has to calculate how much each of the students has to pay/receive to/from the others. Most of it, we got from our teacher. The error we are getting is that we have to 'take care of the input/output order'. So if you type in the names/numbers of the students in a different way, so for example if you type first number 1, then 0, then 2 and 0 and 1 have to pay money to number 2, number 0 has to be in front of 1. Our output is that number 1 is in front of number 0.

I'm learning C++. Is there some way to make program function on input from a port like usb port and can I send bits through the port? For example A usb cable connected to a circuit. I press a button and an AND gate on the circuit gets activated by a bit from the usb port and a fan in the room turns on.

I want to create a function that will accept input from the user and return the input, to be used for further calculation. I know how to accept and return with integers as parameters , but how do i do it with arrays?
Suppose there is an array of numbers arr[]. Now, i want a function that accepts the input from the user, and return the array for further manipulation.
For example, if the array is arr[5], then i should call a function and accept the values from the user. Then, i should return the imputed values and print the same. How can i do this.

Write a program that opens two text files (input1.txt and input2.txt) for input and one for output (output.txt). The program should merge the two input files in the output files. While doing the merge, it will read one line from input1.txt and one line from input2.txt and write those in the output file one after other. Then it will read the next line from input1.txt and next line from input2.txt and write them one after other in the output file.
This is my code:
#include <iostream>
#include <fstream>
#include <string>
using namespace std;
int main() {
ofstream myproject;
myproject.open("input1.txt");
[Code] .....
I need to:
1. how to get the second line in the input1.txt file and so on.
2. After the writing in output.txt, count the number of lines in output.txt.
3. write the number of times term ‘line’ appears in output.txt file.

Alright, so to better myself with network logic I've decided to make a small net game.
I need to input commands to the console as well as output status updates at the same time. I'd prefer to write a gui interface for that, but I'd rather work with WinAPI as little as possible (I mean, look at the way it's designed...).
I'd like to do this with standard operations, limiting dependencies is a must for me.

Ok so This is what the output of the program should be.
enter the count of input integers: 1
The count of the integers must be two or more. Please enter a valid number : 3
Enter integer #1 : 2
Enter integer #2 : -1
Enter integer #3:5
The positive numbers entered and their squares are:
2 4
5 25
My Code :
//header files
#include<stdio.h>
