C in 100 Seconds: For Loops — Init Condition Step | Episode 8

The for loop packs init, condition, and step into one line. i starts at one, runs while it's five or less, and adds one after each pass. Five iterations, five numbers. Nest two for loops and you get a grid — an outer loop for rows, an inner loop for columns. For every row, the column loop runs all the way through before the next row starts. Init, condition, step — compact and predictable.
