卢杨廖13458997012 ______ 为了说明方便,给每个语句前面加上行号1 for i=1 to 32 for j=i to 13 a=a+14 next j5 next i6 print a 程序执行语句1时,循环初值 i=1 小于终值3,所以程序执行语句2-4 语句2 因i=1,所以循环初值 j=1 等于终值1,所以程序执行语句3 ( a=a+1),如果...

卢杨廖13458997012 ______ “j Mod 2 0和j mod 2 = 0的情况不是各循环了4次”是不错!但:循环到“j Mod 2 0”时,内循环里的“a = a-1”与外循环里、内循环外的“a=a+1”共同的结果使a值保持不变.而每次循环到“j mod 2 = 0”时,内循环里的“a = a-1”不执行,外循环里、内循环外的“a=a+1”却执行1次,所以4次后使a值由0变为4了.所以“答案是a =4”.
