Thanks in advance for getting here and trying to see my bad code.

So, I have some trouble on trying to "sell" tickets to people and give them the possibility to buy >=1.

Now, the problem, is that i can't associate an array of 6 numbers to the ticket.

What is wrong? Thanks!

CodePudding user response：

picket.ticket = [1,2,3,4,5];

Here you're trying to assign an array of 5 items to an array of 6 items. You need to explicitly define the 6th value - which is the default value of 0.

Also, since you're passing hardcoded low values, the compiler incorrectly marks them as uint8. You need to cast at least the first one to uint256 (or its alias uint) for the compiler to recognize the correct datatype.

picket.ticket = [uint256(1), 2, 3, 4, 5, 0];
