Exiting a true Boolean expression after execution in an if statement in c++

I need to write a program that will evaluate a Boolean expression in an if statement such that if it is true it takes that branch but doesn't stop at the end of the branch. It should continue and GET OUT of the if statement (ofcourse skipping the else / else if) but going to the other parts of the code outside. I'm a beginner, writing in c++, please bare with me.

Thanks
