Calculate and display sin⁡(1x)\sin(\frac{1}{x})sin(x1) for a real number xxx

Write a C program that accepts a real number x and prints out the corresponding value of sin(1/x) using 4-decimal places.

Note: Use 4-decimal places.
Test data and expected output:
Input value of x:
Value of sin(1/x) is 0.8415

Sample Solution:

C Code:

#include <stdio.h> 
#include <math.h>
int main() {
    double x, tval;

    // Prompt user for input
    printf("Input value of x: \n");

    // Read the input value
    scanf("%lf", &x);

    if (x != 0.0) {
        // Calculate sin(1/x) if x is not zero
        tval = sin(1/x);
        printf("Value of sin(1/x) is %0.4lf\n", tval);
    } else {
        // Display error message if x is zero
        printf("Value of x should not be zero.");
    }

    return 0;
}

Sample Output:

Input value of x: 
Value of sin(1/x) is 0.9995
