Programming Example
C Program to Calculate Area of Equilatral Triangle
In this program we will Calculate Area of Equilatral Triangle
#include"stdio.h"
#include"math.h"
int main() {
int side;
float area, r_4;
r_4 = sqrt(3) / 4;
printf("\nEnter the Length of Side : ");
scanf("%d", &side);
area = r_4 * side * side;
printf("\nArea of Equilateral Triangle : %f \n", area);
return (0);
}Enter the Length of Side : 6
Area of Equilateral Triangle : 15.588457

First read the algorithm, then study the program code line by line. After that, compare the code with the output and finally go through the explanation. This approach helps learners understand both the logic and the implementation properly.
After understanding this example, try to rewrite the same program without looking at the code. Then change some values or logic and run it again. This helps improve confidence and keeps learners engaged on the page for longer.
