Ask the right questions to secure the right Fortran talent among an increasingly shrinking pool of talent.
Fortran, which stands for “Formula Translation,” is a high-level programming language that was created by IBM in the 1950s. It is one of the oldest computer languages that is still used today. It was designed for scientific and engineering computations due to its ability to handle complex numerical calculations. The language revolutionized software development and set a precedent for future programming languages like ALGOL and COBOL. Fortran has stayed useful for a long time because it is always getting better. The most recent version, Fortran 2018, was released by ISO/IEC. Its historical significance and ongoing utility make it a cornerstone in the field of computer programming.

Top Fortran Interview Questions
Here are some of the most common Fortran interview questions that will get to the heart of the matter:
-
1 What are the advantages of strength reduction in FORTRAN?
- This question assesses your understanding of optimization techniques and how they can be applied to improve Fortran code efficiency.
- Answer: Strength reduction involves replacing expensive operations with less computationally intensive ones, leading to faster execution times.
-
2. Explain the method of Dead store elimination in FORTRAN.
- This question probes your knowledge of compiler optimization techniques and their role in eliminating unnecessary computations.
- Answer: Dead store elimination identifies and removes assignments to variables that are not subsequently used, reducing code bloat and improving performance.
-
3. Describe the optimization techniques commonly used for code optimization in FORTRAN.
- This question delves deeper into various optimization strategies and their suitability for different scenarios.
- Answer: Common optimization techniques include loop unrolling, constant folding, and common subexpression elimination, each tailored to specific performance bottlenecks.
-
4. Discuss the common pitfalls associated with data types in FORTRAN.
- This question highlights the importance of data type selection and its impact on code accuracy and efficiency.
- Answer: Pitfalls include choosing inappropriate data types for variables, leading to potential precision loss or memory allocation issues.
-
5. Outline the rules involved in debugging FORTRAN programs.
- This question assesses your debugging skills and your ability to identify and rectify errors in your code.
- Answer: Effective debugging involves using tools like print statements, debuggers, and code analysis to pinpoint the source of errors and implement appropriate fixes.
-
6. Explain the procedure for testing a FORTRAN program.
- This question emphasizes the importance of thorough testing to ensure the correctness and reliability of your code.
- Answer: Testing involves creating test cases that cover various input scenarios and verifying the program’s output against expected results.
-
7. Describe the methods used to correct syntax errors in FORTRAN.
- This question tests your understanding of Fortran syntax and your ability to identify and resolve syntax-related issues.
- Answer: Methods include carefully reviewing error messages, consulting documentation, and utilizing debugging tools to pinpoint the location and nature of syntax errors.
-
8. Discuss the options provided by the compiler during FORTRAN programming.
- This question explores the compiler’s role in optimizing and generating executable code from your Fortran source code.
- Answer: Compilers offer options such as optimization levels, code generation targets, and error reporting levels, allowing you to customize the compilation process.
-
9. Write a program in FORTRAN that demonstrates dynamic memory allocation.
- This question assesses your practical programming skills and your ability to apply dynamic memory allocation techniques.
- Answer: Provide a code example that allocates memory at runtime using the ALLOCATE statement and deallocates it using the DEALLOCATE statement.
-
10. Enumerate the features introduced in FORTRAN 2008.
- This question tests your knowledge of the latest Fortran standard and its enhancements.
- Answer: Features include interoperability with C, object-oriented programming constructs, and improved array handling capabilities.

Describe the difference between a function and a subroutine in Fortran.
In Fortran, a function gives back a value that can be used in an expression. A subroutine, on the other hand, doesn’t give back a value and is used for its side effects.
How would you write a function in Fortran?
The function keyword, the function name, arguments, and return type are written after the function keyword in Fortran. The function body contains the code to be executed, and the function ends with end function.
