apmatrix

AP Computer Science Workshop

AP Classes: apmatrix

Code Effect

apmatrix<char> a; constructs a 0 element matrix

apmatrix<int> a(5, 10); constructs a 5 row by 10 column matrix

apmatrix<int> b(5, 10, 0); constructs a 5x10 matrix initialized to 0

b = a; assignment works

b.numrows(); returns number of rows (5)

b.numcols(); returns number of columns (10)

a[0][9] = 123; assigns 123 to first row, tenth column

a[0,9] = 123; illegal!!!

b.resize(10, 100); expandable matrices, too!

Code	Effect

`apmatrix<char> a;`	constructs a 0 element matrix
`apmatrix<int> a(5, 10);`	constructs a 5 row by 10 column matrix
`apmatrix<int> b(5, 10, 0);`	constructs a 5x10 matrix initialized to 0

`b = a;`	assignment works
`b.numrows();`	returns number of rows (5)
`b.numcols();`	returns number of columns (10)

`a[0][9] = 123;`	assigns 123 to first row, tenth column
`a[0,9] = 123;`	illegal!!!

`b.resize(10, 100);`	expandable matrices, too!
