Lets Start with Basics of Program

#include<stdio.h>
#include<conio.h>

void main()
{
clrscr();
printf("Lets\n start Basic of Program");
getch();
}

Briefly explanation of the Above Program

So, here we use  #include<stdio.h> and #include<conio.h> because these two are the header files and there is function defined for these two header files

• And #include means that include these two header files.

void is a datatype which uses with the functions and here it uses with main().

void main() {

all text b-w them

}

1. clrscr(); means clear the output screen.
2. printf (); means show the output text screen.
3. getch(); means hold the output screen.

HEADER FILES                                                 FUNCTIONS DEFINED

stdio.h	printf() scanf() getchar() putchar() gets() puts() fopen(),fclose()
conio.h	clrscr(),getch()
ctype.h	to upper(),to lower()
math.h	pow(),sqrt(),cos(),log()
stdlib.h	exit()
string.h	strlen(),strcpy(),strcmp()
