Generating random numbers

[JackieCho]

for (int i=0; i<15; i++)
    {
        nx[i]=rand()%8+1;
        printf("%d",nx[i]);
    }

I want to the function of timer "srand(time(NULL))" to generate seed for random numbers.
By running this for loop,I think I should expect random numbers ranging from 1 to 8.However, I get some wried numbers from the console window like 88,044,077,066,088,088,066,022,044,044,088,022,033,66814990522,-156026525933,1606416712. One more thing,I think I am going to have 15 outputs, but why I get 16 instead every time.

Can anyone help me with that?

The snippet of code you posted works OK for me after adding in a few more lines. Do you have the array defined differently?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15

#include <cstdlib> #include <ctime> #include <cstdio> int main() { int nx[15]; srand(time(NULL)); for (int i=0; i<15; i++) { nx[i]=rand()%8+1; printf("%d",nx[i]); }
