你能在if子句中存储一个变量吗？

if (x := 10) > 5:
    print("x is greater than 5")

if ((x = 10) > 5) {
    console.log("x is greater than 5");
}

int x;
if ((x = 10) > 5) {
    System.out.println("x is greater than 5");
}

int x;
if ((x = 10) > 5) {
    Console.WriteLine("x is greater than 5");
}

int x;
if ((x = 10) > 5) {
    std::cout << "x is greater than 5"<< std::endl;
}
