This function is overloaded in and (see complex pow and valarray pow). Additional overloads are provided in this header ( ) for other combinations of arithmetic types ( Type1 and Type2 ): These overloads effectively cast its arguments to double before calculations, except if at least one of the arguments is of type. The pow function computes a base number raised to the power of exponent number. The pow function computes a base number raised to the power of exponent number. C Language: exp function (Exponential) In the C Programming Language, the exp function returns e raised to the power of x. The syntax for the exp function in the C Language is. C for loop - A for loop is a repetition control structure that allows you to efficiently write a loop that needs to execute a specific number of times.
C++ Program to Generate Fibonacci Series
Fibonacci Series is in the form of 0, 1, 1, 2, 3, 5, 8, 13, 21,...... To find this series we add two previous terms/digits and get next term/number.

You can write and run your C++ unit tests by using the Test Explorer window. It works just like it does for other languages. For more information about using Test Explorer, see Run unit tests with Test Explorer.
Note
Some features such as Live Unit Testing, Coded UI Tests and IntelliTest are not supported for C++.
Visual Studio includes these C++ test frameworks with no additional downloads required:
Along with using the installed frameworks, you can write your own test adapter for whatever framework you would like to use within Visual Studio. A test adapter can integrate unit tests with the Test Explorer window. Several third-party adapters are available on the Visual Studio Marketplace. For more information, see Install third-party unit test frameworks.
Visual Studio 2017 and later (Professional and Enterprise)
C++ unit test projects support CodeLens.
Visual Studio 2017 and later (all editions)
Visual Studio 2015 and earlier
You can download the Google Test adapter and Boost.Test Adapter extensions on the Visual Studio Marketplace. Find them at Test adapter for Boost.Test and Test adapter for Google Test.
Basic test workflow
The following sections show the basic steps to get you started with C++ unit testing. The basic configuration is similar for both the Microsoft and Google Test frameworks. Boost.Test requires that you manually create a test project.
Create a test project in Visual Studio 2019
You define and run tests inside one or more test projects. You create the projects in the same solution as the code you want to test. To add a new test project to an existing solution, right-click on the Solution node in Solution Explorer. In the pop-up menu, choose Add > New Project. Set Language to C++ and type 'test' into the search box. The following illustration shows the test projects that are available when the Desktop Development with C++ and the UWP Development workload are installed:
Create a test project in Visual Studio 2017
You define and run tests inside one or more test projects. You create the projects in the same solution as the code you want to test. To add a new test project, right-click on the Solution node in Solution Explorer and choose Add > New Project. In the left pane, choose Visual C++ Test. Then, choose one of the project types from the center pane. The following illustration shows the test projects that are available when the Desktop Development with C++ workload is installed:
Create references to other projects in the solution
To enable access to the functions in the project under test, add a reference to the project in your test project. Right-click on the test project node in Solution Explorer for a pop-up menu. Choose Add > Reference. In the Add Reference dialog, choose the project(s) you want to test.
Link to object or library files
If the test code doesn't export the functions that you want to test, you can add the output .obj or .lib files to the dependencies of the test project. For more information, see To link the tests to the object or library files.
Add #include directives for header files
Next, in your unit test .cpp file, add an
#include directive for any header files that declare the types and functions you want to test. Type #include ' and then IntelliSense will activate to help you choose. Repeat for any additional headers.
To avoid having to type the full path in each include statement in the source file, you can add the required folders in Project > Properties > C/C++ > General > Additional Include Directories.
Write test methods
Note
This section shows syntax for the Microsoft Unit Testing Framework for C/C++. It is documented here: Microsoft.VisualStudio.TestTools.CppUnitTestFramework API reference. For Google Test documentation, see Google Test primer. For Boost.Test, see Boost Test library: The unit test framework.
The .cpp file in your test project has a stub class and method defined for you. They show an example of how to write test code. The signatures use the TEST_CLASS and TEST_METHOD macros, which make the methods discoverable from the Test Explorer window.
TEST_CLASS and TEST_METHOD are part of the Microsoft Native Test Framework. Test Explorer discovers test methods in other supported frameworks in a similar way.
A TEST_METHOD returns void. To produce a test result, use the static methods in the
Assert class to test actual results against what is expected. In the following example, assume MyClass has a constructor that takes a std::string . We can test that the constructor initializes the class as expected like so:
In the previous example, the result of the
Assert::AreEqual call determines whether the test passes or fails. The Assert class contains many other methods for comparing expected vs. actual results.
You can add traits to test methods to specify test owners, priority, and other information. You can then use these values to sort and group tests in Test Explorer. For more information, see Run unit tests with Test Explorer.
Run the tests
For failed tests, the message offers details that help to diagnose the cause. Right-click on the failing test for a pop-up menu. Choose Debug Selected Tests to step through the function where the failure occurred.
For more information about using Test Explorer, see Run unit tests with Test Explorer.
For more information related to unit testing, see Unit test basics
Use CodeLens
Visual Studio 2017 and later (Professional and Enterprise editions)
CodeLens lets you quickly see the status of a unit test without leaving the code editor.
You can initialize CodeLens for a C++ unit test project in any of these ways:
After it's initialized, you can see test status icons above each unit test.
Click on the icon for more information, or to run or debug the unit test:
