Despite the power of formal debuggers, with their ability to peer into the depths of what is going on in your code, many of us still debug with what is sometimes called the “printf debugger”.
With the name coming from C, this practice of sprinkling printf (or moral equivalent) statements throughout your code can be used [...]
