C-language operator precedence, like Lion Tiger Leopard Memory method

Remember when you were a child of the beast Chess, mice can eat elephants, haha. --like lion Tiger Leopard, dog Wolf Cat Mouse.

We divide the C language operator level 15 priority into 8 groups, each of which takes a representation. As follows:

Why do you do this:

1. Human beings are suitable for memory of 10 or less, and 15 are not well remembered.

2. Of the 15 priorities, some do not create disputes, such as the 1th and 2 priorities, a[3]++, which is natural, they can be merged, easy to remember. Also, do you write an expression such as a < b = = c > d? Therefore, relational operators can also be merged. The most common dispute is a & 7 = = 3, this time, because the tiger to eat leopard, so to protect the leopard, (A & 7) = = 3.

3.8 numbers better memory than 10 digits. Although 10 binary is more suitable for counting than 8, the memory should be 8 digits more suitable for memory.

4. Everyone likes these 8 kinds of animals.
