A C++ Program to Reverse the 5 Digit number.

/*In this program we find the quotient & remainder. This program runs until the variable 'n' not becomes equal to 0 and during this remainder in multiplied with multiplier variable 'm' which initially equals to 10000(Five Digits ) and as the loops progresses it will reduced further (with division by 10) . The multiplied quotient will be added with reverse number in each iteration and original is also divided 10.*/
