A student's question

My teacher keeps drilling into our collective heads that using the break command is harmful, and that if we wish to terminate a loop early it would be far better to create a boolean variable, set it to 0, and add a condition to the head of the loop, and set the boolean variable to 1 when a break is needed. Note that this way you actually have to check this every single loop (where it is not needed almost every time) as well as waste a command to reset the boolean in case it was set to true.

Is there a reason to this?

it uses goto which is by some considered bad. Why? Goto makes programs harder to read and analyze.

also, why not just:

for(int ii=0; ii<1000; ii++) {
    for(int jj=0; jj<1000; jj++) {
        for(int kk=0; kk<1000; kk++) {
            if(wantToBreak) {
                kk=1000;
                jj=1000;
                ii=1000;
            }
        }
    }
}
"breaks" from nested loops without the need of defining extra variable / checking it every loop
