The position of the number is important ? <br />
So is equal 135, 351, 531, 513 or do you count it like a diferent combination ?

<div class="content wysiwyg-content">
Is there a function or a library which has a function for this problem : I have x numbers (e.g 5) , and I want to list all possible combinations in of these numbers taken y (e.g 3) at a time. For example, let's say we have these 5 numbers: 1, 3, 5, 6, 7 , I want to print all the possible combinations taken 3 at time, which means 135, 356,567 etc etc.<br />
<br />
If there is not such function, can you provide me the basic guidelines to build such a function? thanks a lot.

List all  possible combinations of x numbers taken y at a time , in C++

C++ is an intermediate-level general-purpose programming language, not to be confused with C or C#. It was developed as a set of extensions to the C programming language to improve type-safety and add support for automatic resource management, object-orientation, generic programming, and exception handling, among other features.

A programming language is a formal constructed language designed to communicate instructions to a machine, particularly a computer. Thousands of different programming languages have been created, mainly in the computer field, and many more still are being created every year. The description of a programming language is usually split into the two components of syntax (form) and semantics (meaning). Some languages are defined by a specification document (for example, the C programming language is specified by an ISO Standard), while other languages (such as Perl) have a dominant implementation that is treated as a reference. Some languages have both, with the basic language defined by a standard and extensions taken from the dominant implementation being common.
