Random Number function problem

[armen_shlang]

I have a function like such

#include <cstdlib>

inline int randInt(int limit)
{
    return limit <= 1 ? 0 : (rand() % limit);
}

And i use it as followd

if(randInt(2) == 1)
{
   column = ((randInt(2) == 1) ? (lastTemp.c + randInt(4)) :   (lastTemp.c - randInt(4)));
   row = lastTemp.r;
}
else
{
  column  = lastTemp.c;
  row = ((randInt(2) == 1) ? (lastTemp.r + randInt(4)) : (lastTemp.r - randInt(4)));
}

And my lastTemp.c and latTemp.r are both = 0;
I get the same sequence every time. which is
r - c
0 - 0
0 - 3
1 - 0
2 - 1
0 - 2
3 - 0

how come i dont get 2 - 0 ?

Try stepping through in the debugger.

Until you get it working, you may want to try to simplify your code so you don't have so much going on one one line. You may have more lines of code, but sometimes that's a good tradeoff to make it more readable and easier to debug.

Your code looks fine to me.

I suspect that you forgot to call srand( time( NULL ) ); at the beginning of your program.

Hope this helps.
