Convert my J.s code to C++

//Ignore the graphics.My goal is to print the most occurred number,which in this case is 7.

    count ++;

    for (var i = 0; i < 100; i ++) {

        num[floor(random(6) + 1) + floor(random(6) + 1)] ++;

    }

    background(255);
    fill(0);
    for (var i = 2; i < num.length; i ++) {

        rect(25 + i*25, 400 - num[i]/42, 17, num[i]/42);
