Please I need help. What is the solution to this problem in C++?

Question

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

Answer 1

Hint: you musst calculate even the rest number of people, which stay after some times of taking 50 pieces. This rest of division will be calculeted with modulo % operator. With this then you can calculate the empty seats.
