To calculate the tax using function in C

C program to calculate the tax of n given number of employees. Use a separate function to calculate the tax. Tax is 20% of basic if basic is less than 9000 otherwise tax is 25% of basic.

C Program

#include <stdio.h>
#include <conio.h>
void cal(void);
void main()
{
	int i,n;
	clrscr();
	printf("\nENTER THE NUMBER OF THE EMPLOYEES: ");
	scanf("%d",&n);
	for(i=1;i<=n;i++)
		cal();
	getch();
}
void cal()
{
	int basic;
	float tax;
	printf("\nENTER THE AMOUNT OF BASIC: ");
	scanf("%d",&basic);
	if(basic<9000)
		tax=basic*20/100;
	else
		tax=basic*25/100;
	printf("\nTHE AMOUNT OF TAX IS %0.2f\n",tax);
}
