    Sorry, I missed you are passing it in; still think that


    ptr_arr[0] = '\0';

    defaults to an int array as in the K & R days.

    FYI: The use of "conio.h" usually means the student is learning from a poor instructor in India.

    This is wrong!



    char exitConditon[]={"0"};


    You need an zero terminated character array to use as an C-String!

    "0" is not equal to 0
