It was a need to think carefully, code blindness issue. I knew if I posted it the lounge I would get cruified by all and sundry needed somewhere to write think and take notice of the abortion I has created.

I am a dummy, I should have seen the problem, in fact I did as I was writing the question. I helps writing out the problem to see it more clearly, You can see the light starting to dawn in the last sentance problem solved.

Boolean gates are not type of transistor but rather cluster of transistors. Is that so? For example the schematic representation of the Not gate has just one line in one line out. A transistor means there is a high voltage line in high voltage line out, low voltage line in low voltage line out. Is the schematic representation showing only the relevant ins and outs?

Well, I mean, it might be relays or something else other than transistors, but essentially correct.

(20*23) + (25*28) + (30*33) + (35*38) +...........+ (m*(m-3)) what is the c programmimg code of the summetion of this series

What have you tried? Can you write the code for evaluating a single term?

You can see the sequence, which uses m*(m+3) not minus:
1. Set m = 20
2. Multiply m by (m + 3)
3. Add the result to the running total
4. Add 5 to m
5. Goto 2.
|
|
|
|
|
M=23 uses (m*(m-3)) or ((m-3)*m)

If m is the first operand, as in (20 * 23) then the formula is m*(m+3). Why would you read it the other way round, or am I missing something mathematical?
|
|
|
|

You substituted (M*(M+3)) for (M*(m-3)).
I'm simply reading what the OP "posted".
I'm the one that's missing something regarding you changing it.

I did not substitute, I corrected. It's pretty obvious that the questioner made a mistake and typed the wrong sign.
|
|
|
|
|
|
That is just a copy of the original question. What is your point?
|
|
|
|
|
|
My presumption would be that OP did not transcribe it correctly.
The sequence as suggested by the dots, rather than the explicit terms, is not defined as it is posted. But is defined with the suggested correction.

Looks like homework for recursion. So look up recursion examples and then modify those.

|
|
And then we'll see the post which says, "my program fails with stack overflow" ...

Well presumably the teacher will provide inputs that do not lead to that.
