然后去执行那个合约的函数，实操。 然后而无需关注具体实现细节，直接调 c 写起来方便的] LFG 🔥
Forge 标准库 [call] and [call] (在 forge 里面 1. 是让你像调用函数一样，直接用高级的抽象去调用其他智能合约合约的函数，你可以通过传入合约地址、 ABI、以及函数选择码（或者签表）来执行调用。2. 是其他 WASM 合约？不知道因为目前不涉及。~
- 使用 **`ICall`** 或者 **`vm.call`** 等高级方法，无需手动构造 calldata。
Forge 标准库提供从低级到高级的不同调用方式，包括直接 ABI 编码调用、使用 `Deploy` 和 `MockCall` 等辅助函数。但我们的重点是理解高级抽象，那就是 `ICall` 和 `vm.call`。它像是帮我们包装了一层，让你可以更直观地调用合约。
对于高级抽象（ICall / vm.call）而言，你会这么用：直接调用 `ICall` ，传递参数无需手动构造 `calldata`。目标是让你更专注于业务逻辑，而不纠结于底层的 ABI 编码。
低级调用：直接用 `address.call()` 手动传 calldata。
高级调用：使用 `ICall` 或 `vm.call`，只要传函数签名和参数即可。LFG 🔥 response: Earn [Call] Calling functions of other smart contracts

Then execute the function of that contract in practice. And without needing to focus on specific implementation details, directly call c makes writing convenient] LFG 🔥
Forge standard library [call] and [call] (in Forge 1. It allows you to call functions of other smart contracts using high-level abstractions, just like calling a function. You can execute the call by passing in the contract address, ABI, and function selector (or signature). 2. Are other WASM contracts? Not sure, because it's currently not relevant.~
- Use advanced methods like **`ICall`** or **`vm.call`** without manually constructing the calldata.
Forge standard library provides various call methods from low-level to high-level, including direct ABI encoding calls, using helper functions like `Deploy` and `MockCall`. But our focus is on understanding the high-level abstraction, which is `ICall` and `vm.call`. They wrap a layer for you, allowing you to call contracts more intuitively.
For high-level abstraction (ICall / vm.call), you would use it like this: directly call `ICall`, passing parameters without manually constructing `calldata`. The goal is to let you focus more on business logic without getting tangled in low-level ABI encoding.
Low-level call: Directly use `address.call()` to manually pass calldata.
High-level call: Use `ICall` or `vm.call`, just pass the function signature and parameters.
