converting Binary Numbers in to decimal numbers

Question

I need a program to convert Binary numbers into Decimal number in Java or in C++.

is there some one who can help me.

Answer 1

In C++, there are the library functions "strtol", "strtoull", etc. that take a string and the base to use for conversion. If you need more than 32 / 64 bits, then you can use the GMP library which is only limited by available memory.
