The assignment problem of comma expression in C language

1, = sign precedence is greater than,
2, the first time a=1, this expression assignment has finished, so the output print is 1, if you want to equal 3, You need to put the numbers in a population

Yours is based on the priority of the operator first, the equal sign is greater than comma, so one is assigned to a, if you put the parentheses around 123, then I assign three to a, this is a question of operator priority, Hope to help you
