Checking for a palindrome

The following code shows the usual (cumbersome) way of checking if an array is a palindrome.

Same Arrays

To check if two arrays are equal, you'd usually write a separate function involving ‘for loop’ as shown below.

Checking for duplicates

Suppose you want to find if your array consist of exactly one occurrence of a specific element this is probably what you'd do :

int, long int or some other data type?

If you’re unsure about how much precision is needed, just let Boost.Multiprecison decide for you. ‘cpp_int’ can be used as the data type in these cases.

Sequence of numbers

The ‘iota_n’ function, can be used to generate a sequence of numbers. The parameters are an output iterator, starting value and the number of values.

Merging vectors in order

If you want to preserve the order of elements in the vector and merge another vector, then ‘push_front’ is the function to use, it only takes the vectors as the parameters. This function adds one vector in front of the other without changing the sequence of elements.

Conclusion

As mentioned before, this by no means is a comprehensive guide. I have only scratched the surface on what's possible using the Boost Libraries. If you find this helpful, I would encourage you to have a look at the official Boost Library documentation wherein you may find some useful libraries and functions that would help you in your project.
