MISRA-C:2004  Rule  14.8:  (Required)			The statement forming the body of a switch, while, do ... while or for statement shall be a compound statement.

For example:

for ( i = 0; i < N_ELEMENTS; ++i )
{
    buffer[i] = 0;       /* Even a single statement must be in braces */
}

while ( new_data_available )
    process_data();       /* Incorrectly not enclosed in braces */
    service_watchdog();   /* Added later but, despite the appearance
                             (from the indent) it is actually not
                             part of the body of the while statement,
                             and is executed only after the loop has
                             terminated */

Note that the layout for compound statements and their enclosing braces should be determined from the style guidelines. The above is just an example.

QAC messages that encompass this guideline:

2212	Body of control statement is not enclosed within braces.
2214	Body of control statement is on the same line and is not enclosed within braces.
