Answer 1

If you absolutely have to keep these variables separate, then the only option you have is to "index" your variables by using an array of pointers and access your variables through it

int ran1, ran2, ran3;

int *rans[3] = { &ran1, &ran2, &ran3 };

for (int k = 0; k < 3; k++)
  *rans[k] = k;

(But maybe you should have used an int array instead of three separate variables from the very beginning.)
