Answer 1

A simple approach to find solution by the logic is
50 pesos= 1 dollor

Answer 2

Well, lets say that we're using signed char's, whose range is -128 to 127.
If you had a number, lets say 100, and multiplied it by 2, you'd get 200 which is too big for the type to handle.
So it wraps around to -128 and starts counting from there.
The final result would be -56.

This is called overflow.
If the reverse happened, it would be called underflow.

The solution would be to use a type that has a bigger range, so that the multiplied value would be stored without causing overflow, or by changing your strategy, for example by not multiplying.

Answer 3

This is a challenge from this app. It's called 'Argentina'. I can't solve it to the end.

Answer 4

The 5th test causes an overflow if you multiply.

Answer 5

It's hard to explain when you don't know English well

Answer 6

Overflowing is like?

Answer 7

Thank you, solved the problem through division, but what you're saying can come in handy later

Answer 8

The Easiest code to solve this problem:

a = int(input(""))
b = int(input(""))
c = int(a / 50)
if c > b:
print("Dollars")
else:
print("Pesos")

Answer 9

A regular unsigned int can only store numbers until about 2.1 billion. After that, it starts over from the bottom (-2.1 billion).

This is called overflow.

You can prevent (or rather alleviate) this problem by using a bigger number type, for example long long.

Answer 12

For anyone who's having trouble understanding I tried to change around the code so it's an easy read

peso = int(input())
USD = int(input())

rate = peso * 0.02

if rate > USD:
print('Dollars')
else:
print('Pesos')

Answer 13

I think there is overflow and your program doesn' t have "return 0;". Good lock
