Answer / Pradeep Kumar Verma
Here's a simple C program that computes the area under an integral using the trapezoidal rule. This program approximates the area under the curve y = f(x) between x1 and x2 by dividing the interval into n equal parts, computing the trapezoids, and summing their areas.nn```cn#include <stdio.h>n#include <math.h>nndouble f(double x); // function to be integratednint main() {n double a = 0, b = 1, n = 100, h = (b - a) / n;n double sum = 0;n int i;nn for (i = 0; i < n; i++) {n double x = a + i * h;n double y = f(x);n if (i == 0 || i == n) y *= 0.5;n sum += y;n }n printf("The approximate area under the curve is: %.16f", sum * h);n return 0;n}nn// Define the function to be integratedndouble f(double x) {n // Replace this function with your desired function.n return pow(x, 2);n}n```
