== Noncompliant Code Example
|
|
|
|
----
|
|
void test(std::vector &v1, std::vector &v2) {
|
|
v1.insert(v2.begin(), v2.begin(), v2.end()); // Noncompliant, the first argument is the insertion location and must be in v1
|
|
v1.erase(v2.begin()); // Noncompliant
|
|
}

|
|
v1.insert(v1.begin(), v2.begin(), v2.end()); // Compliant

v1.erase(v1.begin()); // Compliant
