c - In the below program I was expected Infinite loop as a output. But output is 0, please help me with explain the concept behind it -

- 

void main() {         int i;      int s=0;      while(i<30)      s+=i;      i++;      printf("sum %d",s); }

/output 0,how? expecting infinite loop./

i uninitialized. can have value. if has value greater/equal 30, loop not execute , s remains 0.
