how it can be done

if the number of generating " myArray[i]" for many times depends on a number entered by the user.

for example:.
if the user enter 3

- the program will generate it something like the following

myArray[i] + myArray[i+1] + myArray[i+2] // (1)

else if the user enter 4
the following will be generated

myArray[i] + myArray[i+1] + myArray[i+2] + myArray[i+3] // (2)

i need to use the result of (1) or (2) in another "for loop", as

for(int i =0;i<10;i++)
{
// the problem how to get the following from the previous (1) or (2)
// to make " i " used by the second for loop
myArray[i] + myArray[i+1] + myArray[i+2]

}

in other words
-------------------
i mean that:

1- i don't need sum to be int, i need it as string - any datatype - that helps me to produce some of myarray elements in the form " 1,2,3" - separated by commas.

2- second, look at the follwing example

if i get f(x) = 2x+3

suppose that 2x+3 is generated by for loop and f(x) the object which contains this equation how can i use this equation not the object in another piece of code i.e in another method.

NOW i think you got my question correctly.

please i need your help

in other words
----------------
look:>>

y = "myArray[i]" // where y is string

after i make this equation that was generated by any way...

i need to use "myArray[i]" in a for loop

for example:

for(i=0;i<10;i++)
{

Console.writeline(myArray[i]);

/*here " myArray[i] was gotten from the above equation - y="myArray[i]" which was generated by someway and i don't know what is the result from that way.*/

}

please if you don't understand it again tell me what you don't understand and i will show it for you.

Hello,
you can use ArrayList objects,

Code:

//n is the capacity of your arraylist you get it from user
ArrayList a=new ArrayList(n);
for(int i=0;i<=a.Capacity-1;i++)
{
    a.Add(i);
    textBox2.Text+=a[i].ToString()+",";
}

if you need to use your ArrayList in several methods you should declare it globally,

can you help me doing this program
i need to make the program to take a number between 2,9

and the program make possible combinations in form of sets where {1,2} the same as {2,1}
i don't need the program to display both sets.

also when you give the program a number between 2,9
for example :
for 2
{1,2}
for 3
{1,2,3}
for 4
{1,2,3,4}

and continue displaying all possible combination in a form of sets which contains a number of elements specified by the user of the program.

if you don't understand me please post a reply.
