Compound Statement or Block

Compound or block statements allow you to group other statements together in a block of code.

Syntax

compound-statement ::=
     {[declaration-list][statement-list]}
 
declaration-list ::=
     declaration
     declaration-list declaration
 
statement-list ::=
     statement
     statement-list statement

Description

You can group together a set of declarations and statements and use them as if they were a single statement. This grouping is called a compound statement or a block.

Variables and constants declared in the block are local to the block and any subordinate blocks declared therein unless declared extern. If the objects are initialized, the initialization is performed each time the compound statement is entered from the top through the left brace ({) character. If the statement is entered via a goto statement or in a switch statement, the initialization is not performed.

Any object declared with static storage duration is created and initialized when the program is loaded for execution. This is true even if the object is declared in a subordinate block.

Example

if (x != y)
{
      int temp;
   temp = x;
   x = y;
   y = temp;
}
