Dear Mr xpiotos,
I have fixed the problem. You were right!.

 path = &path[15]

as the name path is same in both the right and left hand side of the equation, there was the problem of path pointing to some other location so what i did was i initialized a new pointer.

 int *p = path

the incoming path is pointing exactly at the 15th index which is now saved inside p. At the end to bring path to center (index 15) i used

 path = p

. and it works just fine I THINK!. At least no more bloody, annoying quitting without any reason. Please try the new code if you are free!.

#include <stdio.h>
#include <stdlib.h>

void readValues(int *numTrials,int *numSteps);
void getDrunk(int *path,int numTrials,int numSteps);
void printPath(int path[],int size);


int main()
{
 int numTrials,numSteps;
 int path[30] = {0};
 int *p;
                  //  printf("%d\n",path[10]);
 
 readValues(&numTrials,&numSteps);  //printf("%d     %d\n",numTrials,numSteps);
 
 p =  &(path[15]);       
 getDrunk(p,numTrials,numSteps);
 
 printPath(path,30);
 
 
 
 
system("pause > null");
return 0;
}


void readValues(int *numTrials,int *numSteps)
{
 printf("Enter the num of trials and steps(strictly <= 15 )\n");
 scanf("%d%d",numTrials,numSteps);

return;
}


void getDrunk(int *path,int numTrials,int numSteps)

 for(i=0;i<numTrials;i++)
  {                                       srand(i*4);   
   
   steps = rand() % numSteps; 
   dir = rand() % 2;  // 0 is back and 1 is forward
   
   if(numSteps % 2 == 0) // even
    {
      if(steps % 2 != 0)
       steps = steps + 1;
       
      if(dir == 0)
       {
        path = path - steps;
        *path = *path + 1;
       }
      else
       {
        path =  path + steps;
        *path = *path + 1;        
       } 
       
    }
