Can someone take a look and verify I am getting the proper results?
#include <stdio.h>
#include <time.h>
int main ( ) {
clock_t start, end;
int i;
long count;
count = 1000000;
start = clock();
printf( "Counting to %d\n", count );
for (i=0; i < count; i ++);
end = clock();
printf( "That took %d seconds and I counted up to %d", (end-start)/CLOCKS_PER_SEC, count );
printf( "\nThat also took %d clock tics\n ", clock());
return 0;
}
Thanks,

Fixed code:
#include <stdio.h>
#include <time.h>
int main ( )
{
clock_t start, end;
long i, count=1000000;
printf( "Counting to %ld\n", count );
start = clock();
for (i=0; i < count; i++)
{
if (count == i-1) end = clock();
}
printf("That took %f seconds and I counted up to %ld", (end-start)/CLOCKS_PER_SEC, count);
printf( "\nThat also took %f clock tics\n", clock());
return 0;
}

How about?
#include <stdio.h>
#include <time.h>
int main ( ) {
clock_t start, end;
long i;
long count;
count = 10000000;
start = clock();
printf( "Counting to %ld\n", count );
for (i=0; i < count; i++);
end = clock();
printf( "That took %f seconds and I counted up to %ld", (end-start)/CLOCKS_PER_SEC, count );
printf( "\nThat also took %ld clock tics\n ", clock());
return 0;
}
Both of the above examples caused some errors when run for me. Thanks anyway. Is there a way to display milliseconds vs just seconds....make it more accurate?

If you are using a Windows compiler, you can use GetTickCount() in <windows.h>
You can divide the seconds with 1000 and you get miliseconds.

#include <stdio.h>
#include <time.h>
int main ( ) {
time_t t;
clock_t start, end;
long i;
long count;
count = 1000000;
start = clock();
time(&t);
printf(ctime(&t));
printf( "Counting to %ld\n", count );
for (i=0; i < count; i ++);
end = clock();
printf( "That took %ld seconds and I counted up to %ld", (((end-start)/CLOCKS_PER_SEC)/1000), count );
printf( "\nThat also took %d clock tics\n ", clock());
return 0;
}
tried this....
If I remember correctly, you cannot use time()/etc for milliseconds. Additionally, you cannot divide the seconds by 1000 to get milliseconds. That is backwards. Consider:
3 seconds
3 seconds / 1000 = .003 seconds? No. This is wrong. To get milliseconds from seconds, you would multiply.
3 seconds * 1000 = 3000 milliseconds.
See? You cannot gain millisecond precision this way.
Quzah.
Hope is the first step on the road to disappointment.

Okay figured out answer through some searches and some local help:
#include <stdio.h>
#include <time.h>
int main ( ) {
time_t t;
clock_t start, end;
long i;
long count;
double x = 0.0;
count = 1000000;
start = clock();
time(&t);
printf(ctime(&t));
printf( "Counting to %ld\n", count );
for (i=0; i < count; i ++);
end = clock();
printf( "That took %f seconds and I counted up to %ld", (((double)(end-start)/CLOCKS_PER_SEC)), count );
printf( "\nThat also took %d clock tics\n ", clock());
return 0;
}
