So, you'll need to fill such a struct with the data you get from the user. Once you have that, you can pass it to strftime.

<pre><code id="code-598708">int week;
 char date[3];
 int year, month ,day;
 struct tm timei;
cout &lt;&lt;&quot;dd-MM-yyyy&quot;;
 cin&gt;&gt; day &gt;&gt; month &gt;&gt; year;

 timei.tm_yday = day;
 timei.tm_mon = month-1;
 timei.tm_year += year-1900;

 strftime(date,3,&quot;%W&quot;,&amp;timei);
 week = atoi(date);
 cout &lt;&lt; week;

i want a user to enter a date than get the week number so far i know how to get the week number by using strftime(date,3,&quot;%W&quot;,&amp;date<wbr />) but dont know how to pass it into date

Development in most programming languages is frequently done with an editor or integrated development environment (IDE). An IDE is a software application that provide comprehensive facilities to computer programmers for software development. An IDE normally consists of a source code editor, build automation tools and a debugger. XCode, Visual Studio, Adobe Dreamweaver and Eclipse are some of the more popular development tools, but an editor or IDE can be anything from simple text editors to sophisticated programs.

Editors IDEs

Microsoft Visual C++ (often abbreviated as MSVC or VC++) is an integrated development environment (IDE) product from Microsoft for the C, C++, and C++/CLI programming languages. It features tools for developing and debugging C++ code, especially code written for the Microsoft Windows API, the DirectX API, and the Microsoft .NET Framework. Many applications require redistributable Visual C++ packages to function correctly and are often installed independently of applications, allowing multiple applications to make use of the package while only having to install it once

Visual C++.NET

C is a general-purpose, imperative computer programming language, supporting structured programming, lexical variable scope and recursion, while a static type system prevents many unintended operations. By design, C provides constructs that map efficiently to typical machine instructions, so it has found lasting use in applications that had formerly been coded in assembly language, including operating systems as well as various application software for computers ranging from supercomputers to embedded systems. It is distinct from C++ (which has its roots in C) and C#, and many later languages have borrowed directly or indirectly from C.
