[QUESTION] Transportation project

Hi all ! I have a little question about the transportation project in SoloLearn. I'm supposed to find the output 24 and use the input 126. I used the following code : int total = 126; int a = total % 50; int b = 50 - a; cout << b; Thus I obtain the output 24 but the programs says it's wrong. I've seen somewhere the good answer is : int total; cin >> total; ... The answer is the same (24) but now it says the answer is right ! And I can't understand why you have to use the cin expression to make it right. Could someone explain it to me ? Thanks people !

It takes input for solving the cases and in c++ you should use cin function to take the user input. Hope it clears your doubt

A simple three lines of code implementation. First, you use the modulus function to find the remainder, which are the passengers on the last bus. Then, to find the empty seats, you use bus capacity minus away the last passengers. https://code.sololearn.com/cAsIKRZH3quK/?ref=app

Oh ok, I just understood thanks to you. I didn't understand at first that we had to ask for user input (since they already give you the total number of passengers as input). It wasn't clear at all to me. So it wasn't about the result but about the steps to go there. Thank you !

This really helped out, it appears that I was looking at the program from a completely incorrect perspective.
