C :: Generate Words From User Input (Phone Number)

Aug 13, 2013

The basic idea of this exercise is to generate words from a user-input, seven-digit number(a phone number). The code runs, but for some reason, I can't get it to print the numbers into the file.

Code:
/*Write a program that will generate a word based on a randomly generated, seven-digit number. there should be 2187 possible words. Avoid "phone numbers" that begin with 0 or 1*/

#include<stdio.h>
#define PHONE 7
void wordGenerator(int number[]);
void wordGenerator(int number[]) {
//loop counters for each digit in the number

C :: Generate Random Numbers

Mar 17, 2013

I'm trying to generate random numbers so that I can assign people to teams. So far I have come up with this

Code:

int generateTeam(){
int i, teamNumber, c, n;
for (c = 0; c <= 5; c++) {
n = rand()%100 + 1;
}

[code]....

}//end generateTeam I'm not sure how to make it so that I can exclude the previous random number when generating the next one. As an example, I have 22 students and I get the number 19. Now I can't have 19 again because that guy already has it.

My program asks me to write a C++ program that generates a random number between 1-100, and lets the user guess the number until he/she guesses correctly.

I have every thing done but my loop will not end. I know I have to "update" the loop to end it but I don't know what that means.

C/C++ :: How To Execute For Loop And Generate A Random Number

Oct 24, 2014

I have to write a C++ program that picks a random number between 0 and 49. If the number is even lets say 30, then the computer will display 30, 32, 34, 36... all the way till 100, if its odd lets say 17, then the computer will display 17, 19.. till 99. I got the computer picking a random number, I just can't figure out how to display every other number using a for loop statement. Here's my code for random number generator:
   
#include <iostream>
#include <cstdlib> 
#include <ctime>  
using namespace std;  
int main()

C :: Generate Pseudo Random Real Number From Interval (0,1)

Feb 6, 2013

How can I generate a pseudo-random real number from interval [0,1] ?

Can it be generalized to any interval? Like [0,a], where 'a' is a parameter?

I tried searching for it, I only found rand(), srand(), random(1), and randomize. None of it actually seems to work for me..

Later I actually succeeded with something like

srand( (unsigned)time( NULL ) );
printf( " %6d
", rand() );

but it only produces up to five digits integers and I cannot divide by 99999 to get it into [0,1].

C++ :: How To Generate Real Random Number From Normal Distribution

Jun 26, 2013

I want to generate random numbers of normal distribution and use scentence like

std::default_random_engine generator;
std::normal_distribution<double> distribution(0,1);
arrayX[i][j]=distribution(generator);

But I find that each time the array I got are the same. So how should I generate random numbers with different seedings with normal distribution?

C++ :: Generate 100 Random Integers Between 0 And 9 And Displays Count For Each Number

May 3, 2013

I've been currently stuck on a C++ problem. Here's the question:

Write a program that generates one hundred random integers between 0 and 9 and displays the count for each number. (Hint: Use rand()

% 10 to generate a random integer between 0 and 9. Use an array of ten integers, say counts, to store the counts for the number of O's, l 's, . .. , 9's.)

I think I'm pretty close, but I keep on getting "0" for the occurrences (or counts) of each random integer.

#include <iostream>
#include <cstdlib>
#include <ctime>
#include <conio.h>
#include <fstream>
using namespace std;
const int SIZE = 100;

C++ :: Generate Numbers For A Binomial Coefficient From Number Interval

Mar 27, 2013

I'm trying to write a code which will generate numbers for a binomial coefficient from a number interval [2-10], i think it should look like this:

n=2
r=2
n=2
r=3
n=2
r=4
n=2
r=5
.
.
.
n=10
r=10
-The program should stop here.

This is badly written, but it still has the basic idea in it.

#include <iostream>
using namespace std;
int main () {
int n=2;
int r=1;

C++ :: Generate Report Based On Input Received From Text File - User Defined Namespace

Nov 11, 2014

Write a program to generate a report based on input received from a text file. Suppose the input text file student_status.txt contains the student’s name (lastName, firstName middleName), id, number of credits earned as follows :

Doe, John K.
3460 25
Andrews, Susan S.
3987 72
Monroe, Marylin
2298 87
Gaston, Arthur C.
2894 110

Generate the output in the following format :

John K. Doe 3460 25 Freshman
Susan S. Andrews 3987 40 Sophomore
Marylin Monroe 2298 87 Junior
Arthur C. Gaston 2894 110 Senior

The program must be written to use the enum class_level :

enum class_level {FRESHMAN, SOPHOMORE, JUNIOR, SENIOR } ;

and define two namespace globalTypes (tys and fys) for the function :

class_level deriveClassLevel(int num_of_credits) ;

The function deriveClassLevel should derive the class_level of the student based on the number of credits earned.

The first namespace globalType tys should derive the class level based on a two year school policy.
and the second namespace globalType fys should derive the class level based on a four year school policy.

Four Year School Policy:
Freshman 0-29 creditsSophomore 30-59 credits
Junior 60-89 creditsSenior 90 or more credits

Two Year School Policy:
Freshman 0-29 creditsSophomore 30 or more credits

NOTE : use ignore() function with ifstream objects whenever you want to ignore the newline character.

For example :
ifstream transferSchoolFile ;
transferSchoolFile.open("student_status.txt", ios::in);

while( !transferSchoolFile.eof()) {
getline(transferSchoolFile,name) ;
transferSchoolFile >> id >> credits;
transferSchoolFile.ignore(); //Used here to ignore the newline character.
….
}

I did this in parts so I got it working with a four year criteria without the user defined name spaces.

include <iostream>
#include <fstream>
#include <string>

using namespace std;
enum class_level { FRESHMAN, SOPHOMORE, JUNIOR, SENIOR };

[Code] ....

So that worked fine then I tried with name spaces -

#include <iostream>
#include <fstream>
#include <string>
using namespace std;
enum class_level { FRESHMAN, SOPHOMORE, JUNIOR, SENIOR };
class_level classLevel;

[Code] ....

I know I have some stuff to mess around with but I am currently stuck with two errors, first -

Error1error LNK2019: unresolved external symbol _main referenced in function ___tmainCRTStartupC:UsersstephenDocumentsVisual Studio 2013ProjectsinputConsoleApplication1MSVCRTD.lib(crtexe.obj)ConsoleApplication1

then -

Error2error LNK1120: 1 unresolved externalsC:UsersstephenDocumentsVisual Studio 2013ProjectsinputDebugConsoleApplication1.exeConsoleApplication1
