Integer variable i j k, I = (j = 3)+1; What does k=i*j mean?
Integer variable, indicating that the variable is integer, that is, int variable I = (j = 3)+1; Give j to 3 first, then add 1, and finally give it to I, this step I = 4k = I * J；; I and j are multiplied, and the result is given to k, and the final result is k = 12. That's it.
