Filling a matrix with values from the keyboard
Let the program receive a two-dimensional array as input, in the form of n
lines, each of which contains m
numbers separated by spaces. You can save such data to a two-dimensional array like this:
read(n, m);
set length(a, n);
for i:= 0 to n - 1 do begin
setlength(a[i], m);
for j := 0 to m - 1 do read(a[i][j]);
end;
