Question

How do I remove duplicate elements in an 2d array (C++)?

This is my code, but it does not work:

const int TEST1_NRULES = 4;

const int  MAX_WORD_LENGTH = 20;

    char test1win[4][MAX_WORD_LENGTH+1] = {

        "stop", "no", "no", "no"

    };

   char test1wout[4][MAX_WORD_LENGTH+1] = {

       "family", "po",  "lp", "bro"

   };

 

for (int i = 0; i < TEST1_NRULES; ++i) {

        for (int p = i + 1; p < TEST1_NRULES; ++p) {

            if (strcmp(test1win[i], test1win[p]) == 0) {

                for (int k = i; k < TEST1_NRULES; ++k) {

                    for (int j = 0; j < MAX_WORD_LENGTH; ++j) {

                        test1win[k][j] = test1win[k + 1][j];

                        test1wout[k][j] = test1wout[k + 1][j];

                    }

                }

            }

        }

        

    }
