看到不大懂，请求支援

希望来个好兄弟给我一些较详细的翻译，谢谢！

x的初始值是1
for循环移动循环了9次
当i1=1,循环第一次：x=(x+1)*2=(1+1)*2=4; i1+1，循环继续
当i1=2,循环第二次：x=(x+1)*2=(4+1)*2=10; i1+1，循环继续
当i1=3,循环第三次：x=(x+1)*2=(10+1)*2=22; i1+1，循环继续
当i1=4,循环第四次：x=(x+1)*2=(22+1)*2=46; i1+1，循环继续
当i1=5,循环第五次：x=(x+1)*2=(46+1)*2=94; i1+1，循环继续
当i1=6,循环第六次：x=(x+1)*2=(94+1)*2=190; i1+1，循环继续
当i1=7,循环第七次：x=(x+1)*2=(190+1)*2=382; i1+1，循环继续
当i1=8,循环第八次：x=(x+1)*2=(382+1)*2=766; i1+1，循环继续
当i1=9,循环第九次：x=(x+1)*2=(766+1)*2=1534; i1+1，循环继续
循环结束
输出结果，一共有1534

i1 = 1, x = (x+1)*2 = (1+1)2 = 22 = 4
i1 = 2, x = (x+1)*2 = (4+1)2 = 52 = 10
i1 = 3, x = (x+1)*2 = (10+1)2 = 112 = 22
i1 = 4, x = (x+1)*2 = (22+1)2 = 232 = 46
i1 = 5, x = (x+1)*2 = (46+1)2 = 472 = 94
i1 = 6, x = (x+1)*2 = (94+1)2 = 952 = 190
i1 = 7, x = (x+1)*2 = (190+1)2 = 1912 = 382
i1 = 8, x = (x+1)*2 = (382+1)2 = 3832 = 766
i1 = 9, x = (x+1)*2 = (766+1)2 = 7672 = 1534
i1 = 10退出循环
输出1534

循环进行加减乘除，i1=1赋初值，i1<10给定条件，i1++就是i1=i1+1，如果条件满足就进入循环
