あえて試験だから、このようにコード化するのでしょうか。 170〜260、220〜230の繰り返しなどのように、「判断（IF）」を「繰り返し」に使った流れ図は、 構造化の命令にコード化しづらいです。 センター試験の出題範囲にDO WHILE/DO UNTILなどはないのですかね。 ●出題の元になる流れ図（たぶん？） 過去掲示板のプログラム 　流れ図を描く 　http://freebbs.around.ne.jp/article/b/basic/103/dkoxkw/dkoxkw.html#dkoxkw を使って（プログラムの終りにあるDATA文の差し替える）流れ図を描くことができます。 10 DATA 1,"3","開始","第６問" DATA 8,"3","X","x=" DATA 8,"3","Y","y=" DATA 5,"0<","3≧","X:Y","" DATA 13,"3","│","" DATA 3,"3","X*Y→T","" DATA 2,"","1","" DATA 0,"","","" DATA 0,"","","" DATA 0,"","","" DATA 3,"3","X→Z","" DATA 3,"3","Y→X","" DATA 3,"2","Z→Y","" DATA 0,"","","" DATA 2,"3","1","170" DATA 5,"3=","0≠","Y:0","" DATA 9,"3","X","GCD" DATA 9,"3","T/X","LCM" DATA 1,"","終了","" DATA 0,"","","" DATA 0,"","","" DATA 0,"","","" DATA 13,"0","─","" DATA 13,"0","┌","" DATA 13,"1","└","" DATA 0,"","","" DATA 0,"","","" DATA 0,"","","" DATA 0,"","","" DATA 3,"3","X→R","210" DATA 3,"3","R-Y→R","220" DATA 5,"2>=","3<","R:Y","230" DATA 3,"3","Y→X","" DATA 3,"3","R→Y","" DATA 2,"","1",""
