C Program to Calculate Area of Scalene Triangle
#include"stdio.h"
#include"math.h"
int main() {
int s1, s2, angle;
float area;
float M_PI=3.14;
printf("\nEnter Side1 : ");
scanf("%d", &s1);
printf("\nEnter Side2 : ");
scanf("%d", &s2);
printf("\nEnter included angle : ");
scanf("%d", &angle);
area = (s1 * s2 * sin((M_PI / 180) * angle)) / 2;
printf("\nArea of Scalene Triangle : %f \n", area);
return (0);
}Enter Side1 : 3
Enter Side2 : 4
Enter included angle : 30
Area of Scalene Triangle : 2.998621

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.
