Jump to PostIf this is the original function
int foo(int x) { while(x < 10) x = x + 1; return x; }Then you can do this:
int foo(int x) { if(x < 10) { x = x + 1; foo(x); } return x; }

@ Ancient Dragon, the recursive function is incorrect. foo(x) has to return int. The correct version would be
int foo(int x)
{
if(x < 10)
{
x = x + 1;
return foo(x);
}
return x;
}
