    Lightbulb Array assigning error


    while running the below mentioned code i got a error can any one help to fix these error.
    The error message is"cannot convert 'int (*)(s) to int*' in function main() " and "'p' is assigned a value that never used in function main()"

      int s[4][2] = {
        {123, 33},
        {124, 35},
        {125, 36},
        {126, 37}
      int (*p)[2];
      int i, j, *pint;
      for (i = 0; i <= 3; i++) {
        p = &s[i];
        pint = p;
        for (j = 0; j < 1; j++)
          printf("%d", *(pint + j));

    What are you trying to do?

"Finding the smallest program that demonstrates the error" is a powerful debugging tool.

    pint = p[0];
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.

    Which one do you want?
    int (*p)[2];    // pointer `p` to array of 2 int's
    int *p[2];      // array `p` of 2 pointers to int
