1 Lecture 11: Passing to Functions PIC 10A Todd Wittman A Comment on Comments When commenting your homework, QUANTITY QUALITY !!! Some students are commenting every line of code, but the comments are mostly meaningless. int x = 1; //Sets integer x=1. while ( x < 20 ) { //This is a while loop. cout << x << “ “; //Outputs x and “ “. x = x + 2; //Adds 2 to x. } //Ends the while loop.

Suppose you’re taking a history test. .. Question #1 [20 points]: What were the major causes of World War II? It’s OK to write a long answer to justify your reasoning.

Frodo is a hobbit, Gimli is a dwarf, and Legolas has pointy ears. So what the heck is Gollum? He doesn’t look like anything. How come orcs are so easy to kill? The major causes of World War II were the economic adversity of the Great Depression, political and cultural discontent arising from the conclusion of World War I, and the rise of totalitarian regimes. I thought orcs were supposed to be all fierce and stuff. I thought I was smart. I thought I was right. I thought it better not to fight. I thought there was a virtue in always being cool. So when it came time to fight, I thought I’ll just step aside and that time would prove you wrong and that you would be the fool. I don’t know where the sunbeams end and the starlight begins. It’s all a mystery. To fight is to defend. Now tell me when would be the time that you would stand up and be a man. For to lose I could accept, but to surrender I just wept and regretted this moment that I
