Compound Statement in C

• Compound statement in C is also called a block. A block is a set of statements that are enclosed within the flower braces { }.
• This grouping allows you to treat multiple statements as a single unit, making your code more organized and controllable.

Syntax:

{
    statement1;
    statement2;
    // ...
    statementN;
}

How are Compound Statements Used in C?

Compound statements play a crucial role in structuring your C code and are frequently used in:

Control Flow Structures:

• The body of if, else, for, while, and do-while statements often consists of compound statements.

Functions:

• The entire set of statements within a function’s definition forms a compound statement.

Local Scope:

• Variables declared within a compound statement have a scope limited to that block, promoting modularity and preventing name conflicts.

Pros and Cons of Compound Statement in C:

Pros:

• Enhanced Readability: They visually group related statements, making code easier to follow.
• Scope Control: They restrict the visibility of variables to specific blocks, promoting encapsulation.
• Flexibility: They allow complex logic to be organized within control flow structures.

Cons:

• Overhead (Minor): There might be a slight runtime overhead due to the creation of a new scope for variables within the block. However, this is usually negligible in most applications.
