I need to create A program That makes a 12x10 Array Grid Filled With Random Numbers From 0-99.
Then I need To Allow The User To Input A Number Between 0-99 And Then The program will then search through the array and count how many of the users number there is inside the array.
Code:
#include <iostream>
using namespace std;
int main() {
int input;
int number;
int row=0;
int col=0;
int Array [12][10];

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

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.
The program is to generate random numbers to a file and will have one integer parameter, Open a file and then using a loop write the required number of random numbers to the file. Scale the random numbers from 1 and 100 inclusive. Then closes the file .The last function will read the numbers in the file into your program. so far i have
Code: #include <iostream>
#include <string>
#include <iomanip>

I am trying to generate 3 random numbers between 1 and 6 using a function called generate_rand. but everytime im having an error : no oprators "<<" matches these operands and the last error was :end of file found before the left brace
my program is the following :
# include<iostream>
#include<cstdlib>
using namespace std;
[Code]....
srand (time(NULL));
for(int i=0; i<N; i++) {
points[i].x=(rand()%(32767-(-32767)))+(-32767);
points[i].y=(rand()%(32767-(-32767)))+(-32767);
cout<<"x="<<points[i].x<<endl;
cout<<"y="<<points[i].y<<endl;
}
Im trying to generate random numbers between -32767 and +32767, where im going wrong, this code generates only negative numbers
I'm trying to write a program that generates a random number between 50 and 200. I made a program that generates random numbers, but how to make those random numbers be in-between 50 and 200. Any example of a program that generates random numbers that are confined in-between certain values?

i just search random function, there are random function using rand();but when i compile this code

i ask to you that is function to generate the number, why the number is cannot generate
So I have to generate a random number between 1 and 6 and then store that same random number into an int variable. Eg, if the random number is 4, that must be stored into int i.

View 4 Replies View RelatedI 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.

Assignment on making a program like candy crush but it is called as number crush.
View 3 Replies View RelatedHow 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].
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?
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>

I am just starting out programming and have an assignment due in the near future. the problem is I cant seem to figure it out. I started it already but got stuck cant seem to figure it out. Here is the assignment.
Create a program that will generate a list of 200 random numbers (ranging from 1-1000) and determine the medium, mode, and average of the list of numbers. Have the program display the original list ant then display the list in ascending and descending order on the screen.
This is my coding so far and I am confused to what the constant for array size is
//initialize arrays
string states[ARRAY_SIZE]={"Alabama", "Alaska", "Arizona"};
string capital[ARRAY_SIZE]={"Montgomery", "Juneau", "Phoenix"};
while (play again) {
//generate random index number
int index = rand () % _______
what goes after the rand () % ?
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;

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] ....
