Which key function in generating random numbers in C or in C++ program. When I created a array of 5 numbers and assign that array to access random numbers using the rand() function to get a random value in program but it does not work...
Code:#include <stdio.h>
#include <stdlib.h>
#include <time.h>
int
main (int arg, char *argv[])
{
unsigned int isd = (unsigned int)time(NULL);
int j;
for (j=0; j<5; j++)
{
printf ("ran[%d]= %u\n",
i, ran ());
}
return 0;
}
A pseudorandom number generator (PRNG) is an algorithm for generating a sequence of numbers that approximates the properties of random numbers. Random number generators (pseudo-random, of course) in C; mostly fast one-liners for "inline" use (to eliminate call / return overhead).
Use the following code to produce random number in C.
Code:include <stdio.h>
#include <stdlib.h>
main(int a, char **va)
{
double x;
z = rand()/(RAND_MAX+1.0);
printf("%g\n",z);
}
Code:int nm = random.Next();
The following code returns a random number less than 1000.
int nm = random.Next(1000);
The following code returns a random number between min and max:
private int RandomNumber(int mn, int mx)
{
Random random = new Random();
return random.Next(mn, mx);
}
Code:#include <stdio.h>
#include <stdlib.h>
#include <time.h>
int main ()
{
srand ( time(NULL) );
printf("RND_MAX = ", RND_MAX);
printf ("A number between 0 and RND_MAX : %d\n", rnd());
printf ("A number between 0 and 99: %d\n", rnd() % 100);
printf ("A number between 0 and 9: %d\n", rnd() % 10);
return 0;
}
