C Program to Calculate Area of Equilateral Triangle
- Equilateral triangle is a triangle in which all three sides are equal .
- All angles are of measure 60 degree
- A three-sided regular polygon
#include
#include
#include
void main()
{
int side;
float area,r_4; // r_4 = root 3 / 4
clrscr(); // Clear Screen
r_4 = sqrt(3) / 4 ;
printf("\n Please Enter the Length of Side : ");
scanf("%d",&side);
area = r_4 * side * side ;
printf("\n The Area of Equilateral Triangle : %f",area);
getch();
}

History Of C..
In the beginning was Charles Babbage and his Analytical Engine, a machine
he built in 1822 that could be programmed to carry out different computations.
Move forward more than 100 years, where the U.S. government in
1942 used concepts from Babbage’s engine to create the ENIAC, the first
modern computer.
Meanwhile, over at the AT&T Bell Labs, in 1972 Dennis Ritchie was working
with two languages: B (for Bell) and BCPL (Basic Combined Programming
Language). Inspired by Pascal, Mr. Ritchie developed the C programming
language.
My 1st Program...
#include
#include
void main ()
{
clrscr ();
printf ("\n\n\n\n");
printf ("\t\t\t*******Pankaj *******\n");
printf ("\t\t\t********************************\n");
printf ("\t\t\t\"Life is Good...\"\n");
printf ("\t\t\t********************************");
getch ();
}
Next Step...
#include
#include
void main ()
{
clrscr ();
printf ("\n\n\n\n\n\n\n\n");
printf ("\t\t\t --------------------------- \n\n");
printf ("\t\t\t | IGCT, Info Computers, INDIA | \n\n");
printf ("\t\t\t --------------------------- ");
getch ();
}
