need help

Aug 15th, 2007

C program to perform Matrix operations such as Addition, Subtraction, Multiplication and Transpose according to the user’s choice.
displaying following menu.
------------------
MAIN MENU
------------------
1. MATRIX ADDITION
2. MATRIX SUBTRACTION
3. MATRIX MLTIPLICATION
4. MATRIX TRANSPOSE
5. TO EXIT
---------------------------
Please enter your option <1/2/3/4/5>:

The program should ask the elements of the input matrix or matrices from the user once the required operation is selected. The program should produce a neat output showing both the input and the resultant matrix in matrix form. The program should not be terminated until the user selects the option number 5 (TO EXIT).

OK, so what have YOU managed to achieve so far?
http://www.daniweb.com/forums/announcement118-2.html

This isn't somewhere where you can just dump your assignment and come back after your party expecting a complete answer for you to hand in. You're going to have to pull your own weight.

Re: need help

next you need to put all that code inside an infinite loop so that it will get repeated until someone selects the 5th menu item. Then after printing the menu you need to get user input by calling cin.get(). You also need to write four functions, one function for each of the menu items and call the appropriate function after getting user input.

Don't PM me with questions -- you might get a nasty PM in response. If you have a question then post it in one of the forums.

I'm afraid we can't really help you until you actually code something, and by something I mean something related to the actual problem.

Be cool. dont get panic of programming first.
proceed like this.
1. print the operations that you are going to perform i.e. Add,sub,..
2.get the option(1->addition 2->subtraction 3-> multiplication 4-> transpose)
3.get the input for two matrices if suppose the option is transpose no need to get two matrices just one.
4.put a switch case for each operation
in case 1 call addition function
in case 2 call subtraction and so on
5. print the input matrices and your output

pls provide me guidance. this prog should ask elements of input matrix and produce output which include both input and resultant in matrix form. i've done the following code with functions for the matrix operations. correct me if im wrong. tq.
