SCOPE OF AN if CLAUSE

The scope of an if clause determines a range over which the result of the condition affects. The scope of an if clause is on the statement which immediately follows the if statement. It can be a simple statement or compound statement.

Case 1:

if (a>b) i = i + 1;    // s1 j = j + 1;    // s2 

Case 2:

if (a>b) {   i = i + 1; // s1   j = j + 1; // s2 } 

If in Case 1 the if condition is true, then s1 is executed because s1 is a simple statement.

If in Case 2 the if condition is true, then both statements s1 and s2 are executed because s1 and s2 are enclosed in a compound statement.
