Sometimes two consecutive 'if' statements can be consolidated by separating their conditions with a boolean short-circuit operator.
Example:
void bar() {
if (x) { // original implementation
if (y) {
// do stuff
}
}
}
void bar() {
if (x && y) { // optimized implementation
// do stuff

AvoidBranchingStatementAsLastInLoop

Categories: Style
Remediation Points: 50000
Using a branching statement as the last part of a loop may be a bug, and/or is confusing. Ensure that the usage is not a bug, or consider using another approach.
Example:
// unusual use of branching statement in a loop
for (int i = 0; i < 10; i++) {
if (i*i <= 25) {
continue;
}
break;
}
// this makes more sense...
