Vector
For example, removing zeros from a vector is shown below.
1 2 0 3 0 0 4 0 0 0 5 0 1 2 3 4 5 before afterThe function has two parameters: the vector and the number of elements in the vector.
void RemoveZeros(Vector<int> & list, int & numElts) // precondition: numElts = # of elements in list // postcondition: numElts = # of elements in list, list has no zeros
Matrix
Remove zeros from a matrix as shown below. There might be some problems with this, think about it.
1 2 0 3 0 1 2 3 4 5 0 4 5 0 0 6 7 8 9 1 0 0 6 0 7 0 8 9 1 0 before after void RemoveZeros(Matrix<int> & mat, int & rows, int cols) // precondition: mat is a rows x cols matrix of ints // postcondition: all zeros removed, mat has cols columns (unchanged // from entry), the # of rows may change
