**Task**

Given the meal price (base cost of a meal), tip percent (the percentage of the meal price being added as tip), and tax percent (the percentage of the meal price being added as tax) for a meal, find and print the meal's total cost.

```
#include <bits/stdc++.h>
using namespace std;
// Complete the solve function below.
void solve(double meal_cost, int tip_percent, int tax_percent) {
int total_cost;
total_cost = meal_cost + meal_cost * tip_percent/100 + meal_cost * tax_percent/100;
cout << total_cost <<endl;
}
int main()
{
double meal_cost;
cin >> meal_cost;
cin.ignore(numeric_limits<streamsize>::max(), '\n');
int tip_percent;
cin >> tip_percent;
cin.ignore(numeric_limits<streamsize>::max(), '\n');
int tax_percent;
cin >> tax_percent;
cin.ignore(numeric_limits<streamsize>::max(), '\n');
solve(meal_cost, tip_percent, tax_percent);
return 0;
}
```

thats a nice code but it failed in test case 3 because instead of converting value to int we should use round function it will give you nearby value of double value, using this will be better :)

## include

using namespace std;

// Complete the solve function below.

void solve(double meal_cost, double tip_percent, double tax_percent) {

}

int main()

{

double meal_cost;

cin >> meal_cost;

cin.ignore(numeric_limits::max(), '\n');

}

in python .

i put return instead of print but it doesn't worked.

can you explain why?
