continue Statement

[EwCjE3v7]

The code acts differently to the way I suspected it to.

It prints

Test-2

though I don't know why, Why does this loop end? Should it keep executing, but some how control goes outside the loop. Why?

int main()
{
    while (int sz = 0) { // true
        if (sz <= 0)
            continue; // goes back to condtion, right?
        cout << "Test-1";
    
    cout << "Test-2";
    return 0;
}

I can't find the ending bracket of your while loop.

oh haha. (facepalm)*300

but still same results...

int main()
{
    while (int sz = 0) {
        if (sz <= 0)
            continue;
        cout << "Test-1";
    }
    cout << "Test-2";
    return 0;
}

EDIT:

Unusual, on the C++ Shell, it says

Exit code: 0 (normal program termination)

but does not print anything and when I compile it with clang myself, Test-2 is printed.

User@Unknown ~/Testing $ clang++ -std=c++11 Testing.cpp -o t
User@Unknown ~/Testing $ ./t
Test-2User@Unknown ~/Testing $

It assigns 0 and then checks if the statement is true (not 0) so after creating the variable sz and assigning a value of 0 it checks if 0 is not equal to 1 which is false so it does not enter the loop.

Basically your code is equal to

while(false)
{
    //stuff that will never happen
}

cout << "Test-2";

return 0;

I'm going to give myself another 300 facepalms.

Thanks lads.
