I know this battle is an old chestnut, but for the record do you guys believe
that superfluous flags and great big if-then statements are truly superior
to the goto? (And the break, which is a goto by another name.) E.g.:
while (loopcond) {
for (i=0; i<limit; i++)
if (frob(i) == TRUE)
goto loopagain; /* nice and CLEAN!!! */
...
/* lots and lots of code over many pages */
...
loopagain: ;
}
versus
while (loopcond) {
boolean_flag=FALSE;
for (i=0; i<limit; i++) {
if (boolean_flag == TRUE) {
; /* spin uselessly */
} else if (frob(i) == TRUE) {
boolean_flag=TRUE;
}
}
if (boolean_flag==FALSE) {
...
/* lots and lots of code over many pages */
...
}
}
