This program populates a two-dimensional array of integers, then asks the user what the row and column spacing should be before writing the matrix to stdout. I have part of the program set up already. // Sample runs: // Run #1: // What field width do you want to use? 3 // What row height do you want to use? 2 // 0 1 2 3 4 // // 5 6 7 8 9 // // 10 11 12 13 14 // // Run #2: // What field width do you want to use? 5 // What row height do you want to use? 1 // 0 1 2 3 4 // 5 6 7 8 9 // 10 11 12 13 14 // // Run #3: // What field width do you want to use? 4 // What row height do you want to use? 0 // 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14

// ==== DispMatrix ============================================================

//

// This function writes the two-dimensional array parameter to stdout in row /

// column format. It uses the height and width parameters to provide row and

// column spacing, respectively.

//

// Input:

// matrix [IN] -- the base address of a two-dimensional array of integers

//

// numRows [IN] -- the number of rows in the matrix parameter

//

// height [IN] -- the number of rows each one-dimensional array should

// occupy

//

// width [IN] -- the field width for each integer displayed

//

// Output:

// Nothing

//

// ============================================================================

// ==== InitMatrix ============================================================

//

// This function initializes the two-dimensional array parameter with

// sequentially increasing integer values, beginning with zero.

//

// Input:

// matrix [OUT] -- the base address of a two-dimensional array of integers

//

// numRows [IN] -- the number of rows in the matrix parameter

// Output:

// Nothing
