Program ARRAY 1 AND 2 DIMENSIONS C++

Array 2 Dimensional much in use to create a matrix or table data, while the one-dimensional Array in use to make the results or data that berkoordinat X only. In this post two-dimensional array in use to accommodate the values ​​of a component of mathematical equations. While one-dimensional Array used to hold the result or the value of the equation.
