Write a C program to find the area of a triangle.

Here's a simple C program to find the area of a triangle:

#include <stdio.h>

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

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

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

    // Display the area
    printf("The area of the triangle is: %.2f\n", area);

    return 0;
}

In this program, we first declare variables for the base, height, and area of the triangle. Then, we prompt the user to input the base and height of the triangle using printf and scanf functions. Next, we calculate the area of the triangle using the formula area = 0.5 * base * height. Finally, we display the calculated area using printf.
