Beep() function in C
Introduction: Beep is a function which is used in C programming language. The beep function uses to make a beep sound. In the C language, when we want to generate any beep sound, then we use this function. This function uses to make the tone of the speaker.
The beep function is beneficial for debugging process because it finds the errors. This function is a synchronous function. That means the beep function waits until the program is complete and does not return the caller function from where the beep function calls.
Syntax of the beep () function in C language:
Syntax means the order or arrangement in the program. The syntax is also known as the function prototype. Every function has a syntax value. The syntax of the beep() function is:
beep (x, y);
Parameters of the beep() function in C language:
The syntax is beep (x, y) in the beep function. So in the beep function, we use two parameters, x and y. Here x means the frequency of the sounds, and y implies the duration of the sounds till on. The time duration measured by the Milly second means ms.
Returns Value of the beep() function in C language:
In the beep function, there are two types of return value comes. If the beep function produces the sounds, then the function returns any non-zero value. In this case, if this function does not create any sounds, then the function returns only the zero value. So, these are the two types of returns value of the beep function.
Header file of the floor() function in C language :
Every program contains some header files. For the run of any program, you must need a header file. Without a header file, you can't run any programs. So, we must produce the header file in every program.
It is a file with an extension. The beep() function does not take a double argument.
The primary use of the header file is to propagate the declaration of code files. The beep() function uses to generate the beep sound. The header file of the beep function in the C language is <windows.h>.
It writes in the program as #include <windows.h>.
What is use of beep command?
The Beep function uses to generate beep sounds in the speaker of the PC. It can control the PC speaker and allows different sounds for other events.
Example 1 –
Here we given a example of the beep() function using C language:
#include <stdio.h>
#include <windows.h>
//driver code for this program
int main()
{
//This function beeps the 450 sound of frequency by the 0.3 sec
Beep (450, 300);
getch();
return 0;
}
Output: We compile and run the above program. The result of this above program is:
We can not compile the code in online IDE, but it compiles it offline. And it produces the beep sounds.
To better understand, we give another example of the beep () function.
Example 2 –
Here we given a example of the beep() function using C language:
#include <stdio.h>
#include <windows.h>
int main();
{
int x;
for (x = 0; x < 2; x++){
Beep (423, 500);
}
//sound for the bell
Beep (456, 800);
Sleep (200);
// loop for the jingle sound
for (x = 0; x < 2; x++){
Beep (423, 500);
}
//sound for the bell
Beep (456, 800);
//sound for the rest tones
Sleep (200);
Beep (423, 500);
Sleep (40);
Beep (630, 50);
Sleep (50);
Beep (570, 150);
Sleep (50);
Beep (400, 160);
Sleep (100);
Beep (230, 500);
Sleep (400);
Beep (560,160);
Sleep (50);
Beep (490,400);
Sleep (100);
Beep (630,50);
Sleep (150);
Beep (559,100);
Sleep (50);
Beep (450, 200);
Sleep (200);
Beep (323, 50);
return 0;
}
Output: We are compiling and running the above program. The result of this program is: that by using this beep function, we can generate the sound for the bell and jingle sounds and also generate sound for the various tones. We can also cause many sounds by using this function.
In the above two programs, we have used the beep function; through the programs, we briefly discussed how to write any C language program using the beep() function. The beep() function is to generate beep sounds.
That's why we use the header file <windows.h>. We also share the output of the above two programs.
