How would you be able to use a 2D array in a real-world situation?

What does

**len(string)**do?How would you be able to print an array to make a string, assuming the array was a char array?

Beginning with an initially empty array A, what is the positive

difference between the maximum and minimum non-zero values in the

array after the program is run?

for n = 1 to 4

for p = 1 to 4

a(n,p) = n + p + n*p

next p

next n

for n = 1 to 4

for p = 1 to 4

if (a(n,p) / 2 = int(a(n,p) / 2)) || (a(n,p) / 3 = int(a(n,p) / 3)) ||

(a(n,p) / 5 = int(a(n,p) / 5)) then a(n,p) = 0

next p

next n

end

Take for example a chess board, with a 8 by 8 2D array.

len(string) is for finding the length of strings

loop through every position of the array and print it out

12

34

Draw a map

Finds the length of a string

Use empty array and loop

19-7=12
