how to solve c++ problem without elif and if

Question

here's the question i'm a noob please help

You are making a program for a bus service.
A bus can transport 50 passengers at once.
Given the number of passengers waiting in the bus station as input, you need to calculate and output how many empty seats the last bus will have.

Sample Input:
126

Sample Output:
24

Explanation: The first bus will transport 50 passengers, leaving 126-50=76 in the station. The next one will leave 26 in the station, thus, the last bus will take all of the 26 passengers, having 50-26=24 seats left empty.

seems like it needs and if and some other statements to make it work is there any other way

Answer 1

Yes, it is possible without elif and if, just interpret and analyze the problem then turn it into equation.

You can use operations, % and -.

Modulus (%) ---> To get the passengers from the last bus
Subtraction (-) ---> To get the free seats

Answer 2

This question can be solved without using if elif.
Just by using this one line you can calculate empty seats in the last bus will have.
cout<<50-(no%50);
where no is int type input.

Answer 3

C++ uses "else if" and not "elif".
