一行中以逗号分隔2个变量的golang减量，给出错误

Question

Hi I am new to golang and I am getting the error for the following piece of code.

I have correct the code by creating 2 statements by why can't I do it in a single statement.

for i < j {
// some code
    i--, j-- //error but, I can do i,j = i-1, j-1 
}

Please, can some point to a place where I can read more on this.

Answer 1

That's because both i-- and j-- are statements.

So you either put them on different lines or separate with ;
