C program to list all files and subdirectories in a directory

Here, we get a directory. Our task is to create a C program that lists all files and subdirectories in a directory.

A directory is a place/area/location where a set of file(s) will be stored.

Subdirectory is a directory within the root directory, which, in turn, can have another subdirectory.

In C programming language you can easily list all files and subdirectories in a directory. The following program shows how to list all files and subdirectories in a directory.

//C program to list all files and subdirectories in a directory

Example h2>

Live demonstration

#include <stdio.h>
#include <dirent.h>
int main(void){
   struct dirent *files;
   DIR *dir = opendir(".");
   if (dir == NULL){
      printf("Directory cannot be opened!" );
      return 0;
   }
   while ((files = readdir(dir)) != NULL)
   printf("%s</p><p>", files->d_name);
   closedir(dir);
   return 0;
}

Output

cprograms
..
prog1.c
prog2.c
prog3.c
...
prog41.c
This will return all files and sub-directory of the current directory.

The above is the detailed content of C program to list all files and subdirectories in a directory. For more information, please follow other related articles on the PHP Chinese website!

C   XML Frameworks: Choosing the Right One for YouC XML Frameworks: Choosing the Right One for YouApr 30, 2025 am 12:01 AM

The choice of C XML framework should be based on project requirements. 1) TinyXML is suitable for resource-constrained environments, 2) pugixml is suitable for high-performance requirements, 3) Xerces-C supports complex XMLSchema verification, and performance, ease of use and licenses must be considered when choosing.

C# vs. C  : Choosing the Right Language for Your ProjectC# vs. C : Choosing the Right Language for Your ProjectApr 29, 2025 am 12:51 AM

C# is suitable for projects that require development efficiency and type safety, while C is suitable for projects that require high performance and hardware control. 1) C# provides garbage collection and LINQ, suitable for enterprise applications and Windows development. 2)C is known for its high performance and underlying control, and is widely used in gaming and system programming.

How to optimize codeHow to optimize codeApr 28, 2025 pm 10:27 PM

C code optimization can be achieved through the following strategies: 1. Manually manage memory for optimization use; 2. Write code that complies with compiler optimization rules; 3. Select appropriate algorithms and data structures; 4. Use inline functions to reduce call overhead; 5. Apply template metaprogramming to optimize at compile time; 6. Avoid unnecessary copying, use moving semantics and reference parameters; 7. Use const correctly to help compiler optimization; 8. Select appropriate data structures, such as std::vector.

How to understand the volatile keyword in C?How to understand the volatile keyword in C?Apr 28, 2025 pm 10:24 PM

The volatile keyword in C is used to inform the compiler that the value of the variable may be changed outside of code control and therefore cannot be optimized. 1) It is often used to read variables that may be modified by hardware or interrupt service programs, such as sensor state. 2) Volatile cannot guarantee multi-thread safety, and should use mutex locks or atomic operations. 3) Using volatile may cause performance slight to decrease, but ensure program correctness.

How to measure thread performance in C?How to measure thread performance in C?Apr 28, 2025 pm 10:21 PM

Measuring thread performance in C can use the timing tools, performance analysis tools, and custom timers in the standard library. 1. Use the library to measure execution time. 2. Use gprof for performance analysis. The steps include adding the -pg option during compilation, running the program to generate a gmon.out file, and generating a performance report. 3. Use Valgrind's Callgrind module to perform more detailed analysis. The steps include running the program to generate the callgrind.out file and viewing the results using kcachegrind. 4. Custom timers can flexibly measure the execution time of a specific code segment. These methods help to fully understand thread performance and optimize code.

How to use the chrono library in C?How to use the chrono library in C?Apr 28, 2025 pm 10:18 PM

Using the chrono library in C can allow you to control time and time intervals more accurately. Let's explore the charm of this library. C's chrono library is part of the standard library, which provides a modern way to deal with time and time intervals. For programmers who have suffered from time.h and ctime, chrono is undoubtedly a boon. It not only improves the readability and maintainability of the code, but also provides higher accuracy and flexibility. Let's start with the basics. The chrono library mainly includes the following key components: std::chrono::system_clock: represents the system clock, used to obtain the current time. std::chron

What is real-time operating system programming in C?What is real-time operating system programming in C?Apr 28, 2025 pm 10:15 PM

C performs well in real-time operating system (RTOS) programming, providing efficient execution efficiency and precise time management. 1) C Meet the needs of RTOS through direct operation of hardware resources and efficient memory management. 2) Using object-oriented features, C can design a flexible task scheduling system. 3) C supports efficient interrupt processing, but dynamic memory allocation and exception processing must be avoided to ensure real-time. 4) Template programming and inline functions help in performance optimization. 5) In practical applications, C can be used to implement an efficient logging system.

How to understand ABI compatibility in C?How to understand ABI compatibility in C?Apr 28, 2025 pm 10:12 PM

ABI compatibility in C refers to whether binary code generated by different compilers or versions can be compatible without recompilation. 1. Function calling conventions, 2. Name modification, 3. Virtual function table layout, 4. Structure and class layout are the main aspects involved.
