switch case with two parameters

[vRltwE]

Hi,

I know a switch case with one parameter:

            switch (i) {

                case (0): matrix_tmp[i][j] = 77;

            }

but, how can I pass two parameters?

I tried

            switch (i,j) {

                case (0,0): matrix_tmp[i][j] = 77;

            }

but case (0,0) is not allowed.

You can't. As simple as that.
The closest you can get to your example is this:

switch (i){
    case 0:
        {
            switch (j){
                case 0:
                    matrix_tmp[i][j] = 77;
                    break;
                //...
            }
        }
        break;
    //...
}

or you could use std::pair<int,int> or whatever struct/class you decalre that has 2 or more data members

switch only works for integral types (char, short, long, int, etc.). It can't be used for floating point values and it can't be used for objects.
