a

just need additional sets of [ ]

a

a 3-D array has rows, columns, and rank * Except leaving the size out of the formal parameter

parallel arrays = two or more arrays in which elements with corresponding indexes are related We WILL do this in the next lab *

Parallel Arrays for(row… for(col… { cout > id[row][col]; cout > grade[row][col]; } OR for(row… for(col… { }

cout > id[row][col] >> grade[row][col];

Sum a Row void main(void) { double nums [3][4] = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12}; double sumRow(double [3] [4]); // prototype

cout
