C++ :: Program To Generate Random Number Between 1 To 100 - While Loop Will Not End

Feb 21, 2014

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.

#include <iostream>
#include <iomanip>
#include <ctime>
using namespace std;

int main() {
srand(time(NULL)); //the function that generates random numbers

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 :: Can't Generate Number In Random Function

Jun 16, 2013

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

Code:

#include <stdio.h>
int main(){
int a;
a = rand();
printf("%d",a);
}

[code].....

i ask to you that is function to generate the number, why the number is cannot generate

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++ :: Constant Array Size - Generate Random Index Number

Nov 20, 2014

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

what goes after the rand () % ?

C++ :: Random Number Generation In A Loop

Jan 2, 2014

I've researched this quite a bit and the overwhelming answer I've been seeing for a loop generating the same pseudo-random number is that you're seeing the random number generator inside the loop, but that is not the case with me . . . At least not that I can see.

Basically, as I mentioned, I have a loop "birthing" new bunnies in a loop. And all the new bunnies are being created with the same name and other details.

Here is the code:

void BunnyGraduation::breed() {
for (unsigned int male = 0; male < colony.size(); male++) {
if (colony.at(male).getSex() == Bunny::Sex::MALE && colony.at(male).getRadioactiveMutantVampireBunny() != true && colony.at(male).getAge() >= AGEOFCONSENT) {
for (unsigned int female = 0; female < colony.size(); female++) {

[Code] ....

srand(time(0)); is seeded ONCE in the constructor of the bunny object itself. . . Now, come to think of it, the constructor is called every time an object is created . . . And the constructor contains the srand() . . . and the constructor is being called in a loop. . . So therefore, yes, the srand() is being called inside the loop.

C :: Random Number Generator Inside / Outside A Loop?

Nov 15, 2013

I've been working on a program on and off for around a week now and I've been struggling towards the end of the program.First of all, the program is a maths quiz which generates two random numbers per question.I'll give you one part of my code:

Code:

srand ( time(NULL) ); //seeds the random number generator
int score = 0;
int a = rand()%12 +1; //generates a random num between 1-12
int b = rand()%12 +1;
int c = a+b;
int d;
}

[code]....

I've basically copied the above code 10 times and changed the variables by going through the alphabet e.g.

Code:

int a = rand()%12 +1; //generates a random num between 1-12
int b = rand()%12 +1;
int c = a+b;
int d; all the way to

Code:

int an = rand()%12 +1;
int ao = rand()%12 +1;
int ap = rand()%12 +1;
int aq = an+ao-ap;
int ar;

Now what I'm going to do is remove all the declared variables and create a loop. But my problem is; If I wanted to declare four variables for e.g.

Code:

int a = rand()%12 +1;
int b = rand()%12 +1;
int c = rand()%12 +1;
int d = a+b-c;

Would I place the srand( time(NULL)); inside the loop? it's confusing because I know an example of a basic loop with an array would be:

Code:

#include <stdio.h>
#include <conio.h>
int main(void)
{

int test[5]={21,18,47,21,4};
int I;
int total=0;

for (I=0;i<5;i++)
total += test[I];
}

[code]....

how or where to include the random number generator in the loop and to make it ask 10 questions at random.

C :: Program That Will Generate But Not Display Three-digit Target Number

Oct 6, 2014

Write a program that will generate, but not display, a three-digit "target" number that has three distinct digits. (Hint: use random number generator.) Then, input a maximum of ten user guesses and for each guess, output the number of hits and matches in the guess. Stop when the user guesses the number or runs out of guesses. For example, if the target is 427, the guess 207 has one hit (7) and one match (2).

C++ :: Creating A Random Number Generator Program?

using namespace std;
int main() {
//Re-seed the random-number generator
time_t now;

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.
