creating a grod

Question

Hi.

I want to try storing a representation of a grid and displaying it on screen.Program should read a grid, store it in a 2D data structure and then output it on screen. BLACK cells represented by 1 WHITE cell represented by 0.

INPUT : first line of input consists of two integers (r) and (c) separated by a single space. These are number of rows and columns of the grid. (r) rows of input follows , each containing c characters separated by single space, which specify the colour of the call at that position.

OUTPUT : output representation of a board l, using 1 for black and 0 for white cells. There should be no spaces between cells.

E.g. Sample input of a user:

5 5 //first line for (r) and (c)
0 0 0 0 0
1 0 0 1 0
1 1 1 0 0
0 0 0 0 0
0 0 0 0 0

Sample output:

00000
10010
11100
00000
00000

without spacing.

Please help if possible.

Answer 1

You need to use 2D dynamic vector and then 2 nested for loops 2 times, once for reading and once for displaying.
