Use QM to express conditio statements

[derle]

Hello everyone,

I am a beginner, I want to know how to use QM, express the following statement, thanks in advance.

1.
bool recurse = true;
bool success;

success = zip.AppendFiles("c:/temp/*",recurse);
if (success != true) {
    //do something
    return;
}

2.
if (var1 Starts with "somestring") {
    //do something
}

if (var2 Does not start with "somestring") {
    //do something
}

3.
if (var1 Ends with "somestring") {
    //do something
}

if (var2 Does not Ends with "somestring") {
    //do something
}

4.
if (var1 Is Empty) {
    //do something
}

if (var2 Is Not Empty) {
    //do something
}
