Arrays

Actually i faced a problem in my assignment .. I don't understand the idea of it .. The Question :: --->

write a c++ programe to take a decimal number integer number and displays its equivalent value in binary format.

--> I don't under stand DISPLAYS ITS VALUE IN BINARY FORMAT :D

--> I don't under stand DISPLAYS ITS VALUE IN BINARY FORMAT :D
it's a different system of numeration.

For example:
5₁₀ = 101₂
28₁₀ = 1С₁₆ = 34₈ = 11100₂

Firstly if you don't understand what binary is why're you doing a computing course, go look up that first.
Then all you need to understand is how many bits is in an integer, then just create a for loop to check for high bits and show the output.

I'll try :) .. Thank you all

I think you should display its representation as a character array or an object of type std::string.

Well a character only holds 8bit, and a string holds an array of characters... So not a very wise technique for converting a 32bit number to binary

Just use the number and iterate through the bits
