To Make Logic First We Think That We Have To Traverse Whole Array Form Start To End So we Decide To Use a Loop
First for Loop Taking Input in Array Element By Element Second Displaying Entered Elements
C++ Program to find perfect number
Third for Loop Which is Main For Loop Having an if Condition Which Checks Every Array Element with Key
What is a perfect number?
"Perfect number is a positive number which sum of all positive divisors excluding that number."
For example 6 is Perfect Number since divisor of 6 are 1, 2 and 3. Sum of its divisor is
1 + 2+ 3 =6
and 28 is also a Perfect Number
since 1+ 2 + 4 + 7 + 14= 28
