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 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 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.

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].
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.

I wanted to add that the template argument is needed because its a "special case" but if that doesn't work what would be the next best way to solve this problem. I want to be able to declare the const size of the array outside the class far removed from it actually. I'm actually going off this page

I'm currently working on assignment which requires to generate a random permutation of the first N integers. For example, if N = 4, one possible answer is {3,1,2,4} without duplicates. {3,3,2,4} is not correct
to fill a[4], generate random numbers until you get one that is not already in a[0], a[1], ..., a[n-1]. for a[0] whatever random number you generate can be put in it. So here is my code. It seem to works but sometime it give duplicates.

View 3 Replies View RelatedI am making a class called "bigint" and i have to have a global constant "size". How do I make that global "size" the size of bigint? If "size" is an array and "bigint" is an object how does that work? Heres the instructions for the program..
Requirements:
-You must use the class construct to implement your ADT.
-The ADT bigint need only work for positive numbers.
-Use a global constant value for the maximum size of the bigint that is, a constant sized array.
Implementation:
-The size of the bigint must be specified by a global constant
-A method (constructor) to initialize a bigint to zero.
-A method (constructor) to initialize a bigint to an int value you provide [0, maxint]. Example: bigint(128).
-A method (constructor) to initialize a bigint to a char[] you provide. You can assume what is provided is a valid bigint. Example: bigint("299793").
-A method to write a bigint that prints at most 60 digits per line.
-A method to compare if two bigints are equal. It should return a bool - true if equal and false otherwise.
//VALID:
const int CONSTANT=100;
int integerArray[CONSTANT]={ 0 };
//but after getting input let's say:

// VISUAL STUDIO 13 Says : randomInteger must be a constant; If so?

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.
I just can't seem to get this right. What I want to happen is when the program runs a random word should pop up.
I have included my code. I'm not sure by putting tag around my code.

Write code that will reverse the numbers in the array and then output the numbers to the screen with a copy of the same output loop used with the original numbers.

is it possible to do this. i am trying to get 6 different numbers stored into 6 elements of an array . this is the piece of the code i think there is a problem with. ie my program scans the numbers and then crashes at this point so think it could be something to do with the commented line?
