Delay Function In Dev C
Jan 10, 2017 Since dev-cpp keeps seperate compiter Mingw while Tubo-c was using Borland. However there are several ways to implement/use delay function in cpp code. First way: code#include void delay (int delay) int now=time (NULL); int later=now+. Nov 29, 2016 Delphi is the ultimate IDE for creating cross-platform, natively compiled apps. To use delay function in your program you should include the 'dos.h' header file which is not a part of standard C library. To specify DLLs to delay load, use the /DELAYLOAD option. To set this linker option in the Visual Studio development environment. Open the project's Property Pages dialog box. Delay y Sleep son funciones que mustrea automaticamente la informacion puesto que tiene un parametro que controla el tiempo x pantalla expresado en milisegundos, al comenzar un valor de 1000 en adelante equivale a un segundo.

including the preprocessor directive 'dos.h'.Do tell me if i need to
use any other preprocessor directive.I've posted the errors which i
get when i try to compile for your reference.
1-->C:Dev-Cppbinduration.cpp [Warning] In function `int main()':
2-->24 C:Dev-Cppbinduration.cpp `delay' undeclared (first use this function).
3-->24 C:Dev-Cppbinduration.cpp (Each undeclared identifier is
reported only) .
and also i would request you to explain me the 'compile delay' option
which is given in the compiler options,is this related to my first
part of the question? If yes how?
Most C programmers know the sleep() function, which pauses program execution for a given number of seconds. Seconds are a vast chunk of time, especially in a computer where things happen quickly. So a desire exists for a function that delays execution for smaller slices of time. For that duty you’ll need to code your own function, similar to the delay() function I use.
The delay() function is built upon a C library function called clock().
The clock() function returns a time value in clock ticks, which is based on the processor’s speed. The value returned is of the clock_t variable type. You can use subsequent reads of the clock() function to determine elapsed time.
The following code demonstrates elapsed time as measured by the clock() function:
Here is the sample output I see on my system:
And the clock() function returned 1072.
And the clock() function returned 1107.

Of course, to make the clock() function useful, it helps to know how many clock ticks take place a second. That information is stored in the CLOCKS_PER_SEC constant.
Delay Function In Dev C++
The above code initializes both clock_t variables to the same value at Line 9. Then a while loop spins until the difference between the values is 1. Here’s the output:
Delay Function In Dev Command
It took 999017 ticks to wait one second.
This value should be the same as CLOCKS_PER_SEC which is 1000000.
Close enough.
Delay Function In Dev Code
Because the CLOCKS_PER_SECOND value could be different on each computer, you need to do some math to figure out how to concoct a delay() function that works on all platforms. Below you see my solution, which uses a millisecond duration as the argument to delay().
At Line 26, the delay() function calculates the pause value in milliseconds (one thousandth of a second). The clock_t variables now and then are initialized at Line 27. Then the while loop waits until the proper number of milliseconds have passed.
Feel free to use the delay() function in your code when a short pause is required.
