What Is Microsoft Visual C?

Microsoft Visual C

Microsoft Visual C is a collection of software development tools that enables developers to quickly create GUI and console applications in various programming languages, as well as manage code snippets in Visual Studio.

Visual C Redistributable Package can often be found installed multiple times on one’s machine due to programs that rely on them for proper operation.

Visual Studio

Microsoft Visual Studio is an Integrated Development Environment (IDE) that supports both managed and native code development, making it the perfect place for creating GUI and console applications, web apps, mobile apps and cloud services. Support for multiple languages – C, C++, Visual Basic (VB), Python and JavaScript can all be found within its walls.

Visual Studio includes an advanced source code editor equipped with IntelliSense and an efficient debugger that lets you run and debug applications for the Windows platform. You can use the debugger to pause execution on breakpoints you set, step through code line by line and view variable or register values.

Microsoft also produces the Microsoft Visual C Redistributable package, which installs run-time components of Visual Studio libraries onto non-VS computers for use by programs written with it. This ensures your app can reach more users by being accessible from anywhere the Redistributable is installed.


A compiler converts high-level source code into machine code prior to running programs, using the translation linking-loading model. A compiler stands in contrast with interpreters, which convert each high-level statement one at a time into machine code during program runtime – and typically runs faster.

Compiling C programs requires a command-line compiler that supports both C and the programming environment in which you are writing code. Visual Studio includes this C compiler as part of its integrated Development Environment (IDE), along with other tools needed for compiling code and building libraries for programs.

The Visual Studio Installer includes command-line tools for each version of Visual Studio IDE, with customizable C++ workload options to install only those needed for development purposes. In addition, libraries and header files specific to target architectures will also be installed automatically by this installation process.


Libraries contain pre-written code that helps reduce the amount of code programmers must write themselves. Libraries are commonly used by programs to perform common activities like communicating with databases or managing user input; their reusable nature means it can be called multiple times within one program.

Libraries can be divided into two main categories: static and dynamic. Static libraries are compiled using the compiler and linked into programs at compile time, while dynamic ones can be loaded at runtime for easy updates without the need for recompilation. Both types are widely available on Windows systems.

Upgrade an application from one version of Visual C to another may lead to library changes causing linker errors or warnings, as these libraries have evolved over the years with implementation of new security features, features addition and removal as well as changes made in order to maintain an Application Binary Interface (ABI) compatibility. When upgrading apps from one Visual Studio version to another their libraries must also be upgraded as required.


Debugging stops your program at its current state where a breakpoint was set and allows you to step through its code or run it until reaching another breakpoint. A memory window may also provide insight into its current state.

If you need more insight into an object, property, or simple variable’s inner values, hovering over it will reveal an overlay panel with more information. Clicking its right-pointing arrow enables you to expand it further so as to examine more properties or variables.

Third-party or startup applications can interfere with your system and lead to Microsoft Visual C++ runtime errors, prompting a clean boot as the only solution. Disabling these applications and performing a fresh reboot are ways of solving this issue; you could also try running them in compatibility mode to see if that resolves the error; once fixed, remove compatibility mode so as to prevent future instances; alternatively use the compiler option /showIncludes to ensure all necessary libraries are included within your source code.
