# C program on calculating the amount with tax using assignment operator

CServer Side ProgrammingProgramming

## Problem

Write a C Program to enter the amount in dollars and then display the amount by adding 18% as tax.

## Solution

Let’s consider the restaurant person adding 18% tax to every bill of the customer.

The logic applied to calculate tax is −

value=(money + (money * 0.18));

The money should be multiplied by 18% and add to the money, then the restaurant person can receive the amount from a customer with tax.

## Example

Live Demo

#include<stdio.h>
int main(){
float money,value;
printf("enter the money with dollar symbol:");
scanf("%f",&money);
value=(money + (money * 0.18));
}
enter the money with dollar symbol:250$amount after adding tax= 295.000000 ## Example Let us consider the same program by changing the percentage − Live Demo #include<stdio.h> int main(){ float money,value; printf("enter the money with dollar symbol:"); scanf("%f",&money); value=(money + (money * 0.20)); printf("amount after adding tax= %f\n",value); return 0; } ## Output enter the money with dollar symbol:250$
amount after adding tax= 300.000000
