Expression Statements

Any expression followed by a semicolon forms an expression statement:
expression ;
mikroC executes an expression statement by evaluating the
effects from this evaluation are completed before the next statement is executed.
Most expression statements are assignment statements or function calls.
The null statement is a special case, consisting of a single semicolon (
statement does nothing, and is therefore useful in situations where the mikroC syn-
tax expects a statement but your program does not need one. For example, null
statement is commonly used in "empty" loops:
for (; *q++ = *p++ ;);
/* body of this loop is a null statement */

Selection Statements

Selection or flow-control statements select from alternative courses of action by
testing certain values. There are two types of selection statements in C:
