Comment on create your own time stamp 2 by rouisk

rouisk — Thu, 21 Aug 2008 13:08:39 +0000

it’s most probably due to a cast problem.
The strftime’s prototype is :
size_t strftime(char *s, size_t maxsize, const char *format, const struct tm *timptr);

Hope this will help.

Comment on Pascal Triangle Challenge by adam

that works for applying the spaces, it doesnt answer any questions about the actual calculation of the rows though. you will get a line of 1s decending but how would you go about adding the numbers in the previous row to create the next.

Comment on create a timer by Gianluca

Gianluca — Mon, 04 Aug 2008 07:33:42 +0000

the code is good; I’ve found a lot of similar examples on the net but no one indipendent by the current time/date. For example, in my application, timer run for a lot of time (hours or days) and in the meaning time it is appened that someone has changed the time of the system causing the timer to show an erroneous count (the same automatic legal/solar date change cause the problem).
Can you show an example on how obtain a timer base on system tick count intead on date/time?
thanks

check this college level implementation. Hope this is easy to digest.

#include
#include
main()
{
int level_count = 0, space_count, i, j;

printf(”\n Please enter the number of levels for triangle: “);
scanf(”%d”, &level_count);
printf(”\n Here goes your pascal triangle \n”);
space_count = level_count;
for (i = 0; i < level_count; i++)
{
for (j = 0; j < space_count; j++)
{
putchar(’ ‘);
}
space_count–;
for (j = 1; j = 1; j–)
{
printf(”%d”,j);
}
printf(”\n”);
}
}

Comment on STL Singleton Template by Subash

Subash — Wed, 23 Jul 2008 17:17:42 +0000

Singleton can be implemented in another way as well. We shall declare a static variable in the class. Then in the constructor(which can be public), we will increment the static variable(which is our object instance). If we see the object count exceeding 1, then we can throw from the constructor. By this you can always new for only once from anywhere it is used, and it serves the rule of singleton.
