Chapter 18, Problem 12ICA

Ask users to enter a matrix that could be any size but has a minimum of two columns. Check the matrix dimensions, and if there are fewer than two columns warn users of their error and ask them to enter the matrix again. If the user does not correctly enter the matrix a second time, use an error message to notify the user and terminate the program.

Using a matrix correctly entered by the user with two or more columns, create a new matrix containing the same number of rows and two columns. The first element in each row contains the smallest value in the odd-numbered columns of the corresponding row in the user matrix, and the second element in each row contains the largest value in the even-numbered columns of the corresponding row in the user matrix.

Use formatted output statements to print the results to the Command Window This program should run correctly for any size matrix entered by the user.

Test Case and Sample Output

The smallest value found in the odd-numbered columns:

Row 1 = –4

Row 2 = 1

Row 3 = 3

The largest value found in the even-numbered columns:

Row 1 = 8

Row 2 = 4

Row 3 = –2
