In computing you only need an if$-$then statement and a go$-$to line statement, plus basic arithmetic

operations. Alternatively, you only need a while$-$loop, plus basic arithmetic operations. That is why there

is a diamond on flow$-$charts, but no special shapes other than that. The $($rounded corner$)$ rectangles on

flow charts are for regular arithmetic operations. How do you generate a for$-$loop this way? In other

words, how do you generate a for$-$loop from a while$-$loop?
