Question

C ++ program that will read in prices and store them into a two-dimensional array

// It will print those prices in a table form and the lowest price.

// EXAMPLE

// Input:

// Please input the number of rows from 1 to 10

// 2

// Please input the number of columns from 1 to 10

// 3

//

// Input price of item (0,0): 2

// Input price of item (0,1): 4

// Input price of item (0,2): 6

// Input price of item (1,0): 1

// Input price of item (1,1): 3

// Input price of item (1,2): 5

//

//Output:

//                     2.00 4.00 6.00

//                     1.00 3.00 5.00

//                     Lowest price: 1.00
