Why you should care

[/vc_column_text][vc_column_text]Loop counters shall not be modified in the body of the loop. However other loop control variables representing logical values may be modified in the loop, for example a flag to indicate that something has been completed, which is then tested in the for statement.[/vc_column_text][vc_empty_space][/vc_column_inner][/vc_row_inner][vc_empty_space height=”12px”][vc_empty_space][vc_separator][vc_column_text]

How we detect

[/vc_column_text][vc_column_text]CAST Highlight counts one occurrence each time a “for” loop has its loop counter modified inside its body.

Bad Code

flag = 1;
for ( i = 0; (i < 5) && (flag == 1); i++ ) {
/* ... */
i = i + 3; /* loop counter updated */
}

Good Code

flag = 1;
for ( i = 0; (i < 5) && (flag == 1); i++ ) {
/* ... */
flag = 0; /* not the loop counter */
}
