/* Main function definition */
int main(void)
{
	int empno; //Int variable to store emp number
    char empname[30]; //String variable to store emp name
    int basic; //Int variable to store emp basic

    FILE *empfile; //Create a file pointer to read from input file

	/* Open a file to read from */
    empfile = fopen("empin.txt", "r");

    if (empfile == NULL)
	{
        printf("Error reading file!\n"); //Print an error message if file not found
    }
	else

            /* Create variable to store the total amount */
            int total = basic + (basic * 0.3);

            /* Print the details to the file */
            fprintf(empoutfile, "Empno: %d\nName: %s\nBasic: %d\nTotal: %d\n", empno, empname, basic, total);

            /* Close the file */
            fclose(empoutfile);
