Adding 2 2-D arrays to make a third array 2

[cjones]

Hello

I have an assignment that requires me to add together 2 small 2-D arrays making a 3rd array. I understand how to work with 1 2-D array but don't know how to add 2 arrays together. Any tips, web sites or etc. WOULD BE GREATLY APPRECIATED!

do you mean addition of 2 matrices?
or concat 2-d arrays making 1-d array?

Clarification--I need to write a program that will add the 2 arrays & put the answers in a 3rd array.

first[2][3] + second[2][3] = sum[2][3]

first (name of array)
16 18 23
54 91 11

second (name of array)
24 52 77
16 19 99

the above arrays added together will equal the array
sum
40 70 100
70 110 110

I know I will be using a function & a number of for statements.

You'll need 2 loops, for loops would be ideal, and 2 counters that keep track of the outer and inner indices as you iterate through the loops. The only calculations you will do will occur in the innermost loop.

I could just give you the code, but since this is a homework assignment I'm sure you wouldn't want us to deprive you of the learning experience. For more help, please submit your best attempt (the code).

to cjones:

you'd better follow rbobbitt instruction,
i'll give you a bit hint

you know how to input an array?
the same structure of for loop but instead of inputing values, you just do the evaluation
