To enter Base and Height of a Triangle and to calculate it's Area

 Program:

#include<stdio.h>

#include<conio.h>

void main()

{

    float b, h, area;

    clrscr();

    printf("Enter Base of Triangle : ");

    scanf("%f", &b);

    printf("Enter Height of Triangle :");

    scanf("%f", &h);

    area=((float)1/2)*b*h;        /* or area = 0.5*b*h;  */

    printf("Area of Triangle : %.2f square units", area);

    getch();

}

Output:

Enter Base of Triangle : 10

Enter Height of Triangle : 20

Area of Triangle : 100 square units
