Before We Learn How to Read Complex Array we should first know precedence and associative .

• Precedence : Operator precedence describes the order in which C reads expressions
• Associativity : Order operators of equal precedence in an expression are applied

Before Reading Article You Should know Precedence and Associative Table

 Operator Precedence Associative (),[] 1 Left to Right *,Identifier 2 Right to Left Data Type 3 –

Different Terms From Table –

 () Bracket operator OR function operator. [] Array subscription operator * Pointer operator Identifier Name of Pointer Variable Data type Type of Pointer

```
```
`char (* ptr)[5]`

Step 1 :

• Observe Above Precedence Table
• [] and () have Same Priority
• Using Associativity , Highest Priority Element is decided
• Associativity is from Left to Right First Priority is Given to “()”

```
```

Step 2 :

• Between Pair of Brackets again we have to decide which one has highest priority ? ‘*’ or ‘ptr’ ?
• * and Identifier ptr have Same Priority
• Associativity is from Right to Left First Priority is Given to “ptr”

```
```

Step 3 :

• Assign third Priority to [].
• Write 3 under []

```
```

Step 4 :

• Here Char is Data Type
• Assign Priority 4 to char
```
