c++ using typedef

In C, the `typedef` keyword is used to create an alias or a new name for existing data types. It allows you to define a custom name for a data type, making the code more readable and easier to maintain. Here's a typical usage of `typedef`:

typedef int myInt;  // 'myInt' is now an alias for 'int'

int main() {
    myInt x = 10;
    printf("%d", x);
    return 0;
}

In this example, we use `typedef` to create a new name `myInt` for the existing data type `int`. So, instead of declaring variables as `int`, we can use `myInt`. Both `int` and `myInt` are interchangeable in this case.
