Programming Question

Unread post by Shifat » Mon Aug 22, 2011 8:41 pm

I have a question to ask.... According to the conjecture of Goldbach we can write an even number (>2)..as the sum of two primes, example-8=5+3,90=83+7 etc...... Now I want to write a program using Qbasic (i am novice since).. where I will input an even number greater than 2, and the output will be two primes... I am having a bit problem to make the algorithm,and the sudocode so please help.

Well I submit a way here, please check if it is programmable,
1.Input A
2.P=3
3. Compare- If (A-P) is a prime then N=A-P
print N,P. Goto 6
else go to next step
4. find the next prime form P to A
let the prime is Q
5. P=Q and goto 3
6.end

One approach can be searching each element of the first array individually in the second array.

To write a desktop app, you need to use a framework. I would recommend Qt, a very popular framework. Visit its website: https://www.qt.io/
