Chapter 6, Problem 26E

Explanation of Solution

Justification:

• The given program is used to find first all zero row for n x n matrix.
• They are using goto statement to compute the first all zero row.
• One can develop an alternative way to complete the given program.
• The following program shows a good structured alternative in C language.

        //Initializing the first_row to -1

        first_row = -1;

        //looping

        for (i = 0; i < n && first_row == -1; i++)

        {

            //Assigning the i value to first_zero_row

            first_row = i;

            //Inner loop for assigning matrix value to 0

            for (j = 0; j < n; j++)

            {
