Sep 05, 2011 How to make a digital clock using C by Programming Techniques Published September 5, 2011 Updated February 5, 2019 The following code creates a digital clock using a 1 sec. Provides various functions to delay the time. Sep 25, 2009 but it just shows me in numbers which can't be the real running time. Can please someone help me? The reason I want to know this is in school we started using the dev-c ide which is also with mingw compiler but I guess the configuration is different and I might need that in the feature. On the other hand, in the current implementation, i.e. Using functions draw the clock updates every second by not in the specified window and it interferes with the rest of the open windows. Nov 23, 2015 In this video, I am going to show you how to make hour hand of analog clock. In next video, our clock will be completed.

- @Th.Thielemann both clock and clockt are from the C Standard Library's header of time.h, and therefore do not need the use of std namespace prefixes after the inclusion of their libraries. Wraps that value and function with the std namespace, but it's not required to use.
- Nov 27, 2013 You should put the class prototype in Clock.h, and implement all the Clock member functions in Clock.cpp. In a third file, main.cpp. Write the following code:. A function named printTimeMessage o Should accept one Clock object o Should not return anything. O Print the time with the message:The current time is.

Description
The C library function clock_t clock(void) returns the number of clock ticks elapsed since the program was launched. To get the number of seconds used by the CPU, you will need to divide by CLOCKS_PER_SEC.
On a 32 bit system where CLOCKS_PER_SEC equals 1000000 this function will return the same value approximately every 72 minutes.
Declaration
Following is the declaration for clock() function.
Parameters
- NA
Return Value
This function returns the number of clock ticks elapsed since the start of the program. On failure, the function returns a value of -1.
Example
The following example shows the usage of clock() function.
