Any expression followed by a semicolon forms an expression statement:

expression;

The mikroC PRO for ARM executes an expression statement by evaluating the expression. All side effects from this evaluation are completed before the next statement starts executing. Most of expression statements are assignment statements or function calls.

A null statement is a special case, consisting of a single semicolon (;). The null statement does nothing, and therefore is useful in situations where the mikroC PRO for ARM syntax expects a statement but the program does not need one. For example, a null statement is commonly used in “empty” loops:

for (; *q++ = *p++ ;);  /* body of this loop is a null statement */
