C :: Generate Random Number Between 50 And 200
Oct 15, 2014I'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?

Feb 21, 2014My 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.

Oct 24, 2014I 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.

C :: Generate Pseudo Random Real Number From Interval (0,1)
Feb 6, 2013How 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, 2013I want to generate random numbers of normal distribution and use scentence like
std::default_random_engine generator;

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, 2013I'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.

C :: Generate Random Numbers
Mar 17, 2013I'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.

C++ :: Generate Random Permutation In Array
Feb 16, 2013I'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.

C++ :: Generate Random Data (fast)
Feb 20, 2013I just want to know how fast can C++ generate data? For example, I have a downstream device that is connected to my pc via a Gigabit Ethernet, and I have to generate some pattern and send it over the Gigabit interface.
I was curious if there is a way that I can see how fast I can generate data? I was curious if I can exercise a good portion of the bandwidth ! for example, sending about 600 Mbits/sec.
How do I find out, first, whether I can do this with C/C++, and, second, how do I know how fast I am sending data?
