The NAG Fortran Compiler is widely used for scientific and engineering applications, offering robust features and performance optimizations. However, it also provides some unique extensions for C++ code to take advantage of specific Fortran capabilities. In this blog post, we will explore some of these extensions and how they can enhance your C++ programming experience.

1. MODULE procedure

In Fortran, the MODULE keyword is used to define a module that can contain variables, types, and procedures. The NAG Fortran Compiler allows you to use the MODULE keyword in C++ code to create Fortran-like modules. This can be particularly useful when you want to encapsulate related variables and functions in a single entity.

MODULE myModule
{
    // Define variables
    int myVariable;
    float anotherVariable;

    // Define procedures
    void myProcedure()
    {
        // Implementation
    }
}

With this extension, you can organize your code more effectively and improve its readability and maintainability.

2. FORALL statement

The FORALL statement in Fortran allows concise and efficient array operations. The NAG Fortran Compiler introduces a similar construct in C++ to leverage this functionality. The FORALL statement can simplify code that involves operations on arrays by providing a compact and expressive syntax.

int main()
{
    float a[10], b[10], c[10];

    // Initialize a and b arrays

    FORALL(i : 1:10)
    {
        c[i] = a[i] + b[i];
    }

    // Rest of the code
}

By using the FORALL statement, you can perform array operations more efficiently and concisely, improving both code readability and execution performance.

Conclusion

The NAG Fortran Compiler offers unique extensions for C++ code, allowing you to take advantage of Fortran-specific features in your C++ projects. The MODULE keyword enables you to create modules to encapsulate related variables and procedures, enhancing code organization and maintainability. Additionally, the FORALL statement simplifies array operations, providing a more concise and efficient syntax.

Using these NAG Fortran Compiler-specific extensions for C++ can enhance your programming experience and improve the performance and readability of your code. Give them a try and see how they can benefit your projects!
