[FIXED] What is difference between internal and private in Solidity?

Issue

In Solidity we have four types of access. Two of them are private and internal. What is the difference if both of them can be used inside smart contract and both of them are not visible after deploying?

Solution

Access types:

public - can be used when contract was deployed, can be used in inherited contract

external can be used when contract was deployed , can NOT be used in inherited contract

internal - can NOT be used when contract was deployed , can be used in inherited contract

private - can NOT be used when contract was deployed, can NOT be used in inherited contract
