C program to find the area of a triangle.

• Here, we declare three variables base, height, and area as floats. We then prompt the user to enter the base and height of the triangle using printf() and scanf().
• We then calculate the area of the triangle using the formula area = 0.5 * base * height, and store the result in the area variable. Finally, we print out the area using printf().
• Note that we use %f as the format specifier for floats in scanf() and printf().

#include <stdio.h>

int main() {
   float base, height, area;

   // Get the base and height from the user
   printf("Enter the base of the triangle: ");
   scanf("%f", &base);
   printf("Enter the height of the triangle: ");
   scanf("%f", &height);

   // Calculate the area
   area = 0.5 * base * height;

   // Print the area
   printf("The area of the triangle is %f\n", area);

   return 0;
}

OUTPUT

Enter the base of the triangle: 4
Enter the height of the triangle: 6
The area of the triangle is 12.000000
