Question

Hello, I'm not sure why this doesn't work.

I want a list of 16 random numbers at first, and then I want another list four times the length of the first list, and so on. The last list will be 4096 random numbers long.

Here is the code:

#include<stdio.h>
#include<stdlib.h>

int main(void)
{
int i;
int j=16;

srand (time(NULL));
i = (float)rand()/(RAND_MAX+1);


for(j=16; j<4096; j*=4)
{
printf("This is the start of the size %d vector ", j);
{
for(i=0; i<j; i++)
{
printf("%.3lf ", (float)rand()/(RAND_MAX+1));
}
}
printf(" ");
printf(" ");
}

getche();

return(0);
}


Thanks for your help

Explanation / Answer

please rate - thanks

It works fine.

all I did is change the formatting a bit

#include<stdio.h>
#include<stdlib.h>

int main(void)
{
int i;
int j=16;

srand (time(NULL));
i = (float)rand()/(RAND_MAX+1);


for(j=16; j<4096; j*=4)
{
printf("This is the start of the size %d vector ", j);
{
for(i=0; i<j; i++)
{
printf("%.3lf ", (float)rand()/(RAND_MAX+1));
if((i+1)%10==0)
     printf(" ");
}
}
printf(" ");
printf(" ");
}

getche();

return(0);
}
