Hi Guys,
I'd post this in programming but you lot probably already have the right set up to run this quickly. It won't blow up your computer or anything. You'll need to have a gcc installed.
Call it program.c
compile with
gcc -ansi -Wall program.c
and run with
./a.out
and if you could post the results here I'd appreciate it (only got access to one machine at the moment
). Should take less than a minute on a decent machine (that's why it took over two on this **** piece).
Thanks
Dstat
P.S. it's just comparing 3 ways of using an integer
But I think I've got "speedstep" or whatever it's called ****ing it up on this laptop
#include <stdio.h>
#include <time.h>
#define NUM 2;
main(){
register int a = 2;
int b = 2;
time_t mytime = time(0);
int p[5] = {1,2,3,4,5};
int i=0;
int j=0;
time_t startTime = time(0);
for(j=0;j<900000000;j++){
for(i=1;i<5;i++){
p=p[i-1]*a;
}
}
time_t endTime = time(0);
printf("Testing registers\n");
printf("Start Time is %d \n",startTime);
printf("End Time is %d \n",endTime);
i=0;
j=0;
startTime = time(0);
for(j=0;j<900000000;j++){
for(i=1;i<5;i++){
p=p[i-1]*b;
}
}
endTime = time(0);
printf("Testing raw integer\n");
printf("Start Time is %d \n",startTime);
printf("End Time is %d \n",endTime);
i=0;
j=0;
startTime = time(0);
for(j=0;j<900000000;j++){
for(i=1;i<5;i++){
p=p[i-1]*NUM;
}
}
endTime = time(0);
printf("Testing DEFINED integer\n");
printf("Start Time is %d \n",startTime);
printf("End Time is %d \n",endTime);
}
