The Problem: Buffering of output can lead to unexpected results For example: std::cout << “Doing unrelated stuff” << std::endl; do_stuff(); std::cout << “Doing divide ... “; i = 1/0; // Divide by zero std::cout << “complete\n”; When runs this program prints (on some systems): Doing unrelated stuff Floating point exception8 From this output we can see that the problem is “obviously” in the do_stuff function. What's going on? The problem is that output is being buffered. So the string “Doing divide ...” goes into the buffer, then the program crashes with a divide by zero error, and the output is never displayed. This is where the confusion comes from

Question

The Problem: Buffering of output can lead to unexpected results
For example:
std::cout << “Doing unrelated stuff” << std::endl;
do_stuff();
std::cout << “Doing divide ... “;
i = 1/0; // Divide by zero
std::cout << “complete\n”;
When runs this program prints (on some systems):
Doing unrelated stuff
Floating point exception8
From this output we can see that the problem is “obviously” in the
do_stuff function. What's going on?
The problem is that output is being buffered. So the string
“Doing divide ...” goes into the buffer, then the program crashes with a
divide by zero error, and the output is never displayed. This is where the
confusion comes from
