I'm trying to create 1000 random numbers using an array. I keep getting the same number everytime, though. How do I get 1000 different random numbers? Here's what I have so far:
[LIST=1]
[*]#include "stub.h"
[*]int main()
[*]{
[*] int number[1000], i;
[*] int r[1000];
[*]
[*] for(i=0; i<1000; i++)
[*] {
[*] r[i] = (rand() % 10) +1;
[*] srand(time(NULL));
[*] cout << " " << r[i] << " ";
[*] }
[*] getchar();
[*]
[*] return 0;
[*]}
[/LIST]Jump to Postyou have to call srand() to generate a new set of numbers - and its only called once at the beginning of the program.
#include <stime> ... int main() { srand( time(0) ); }
Ignore the int number[1000];
you have to call srand() to generate a new set of numbers - and its only called once at the beginning of the program.
#include <stime>
...
int main()
{
srand( time(0) );
}If you want those 1000 numbers to have a limit use this:
for (int i=0;i<arraySize;i++) {
a=1 + rand() % limit;
}
}
dont forget to use #include <cstdlib>
