C Programming Recursion Examples, Programs

Recursion is the process by which a function calls itself. In programming languages, if a program calls a function inside the same function, then it is called a recursive call of the function. C programming supports the feature of recursion – with the help of recursion, we can call a function itself.

This section contains the C solved programs on recursion, practice these programs to learn the concept of recursion. Each function has the solved code, output, and explanation.

List of C programming Recursion Examples, Programs

1. C program to read a value and print its corresponding percentage from 1% to 100% using recursion.
   C program to read a value and print its corresponding percentage from 1% to 100% using recursion
2. C program to find factorial using recursion.
   This program will read an integer value and print its factorial using recursion, in this program there will be a function which will calculate factorial by calling itself (recursion).
3. C program to print fibonacci series using recursion.
   This program will print the Fibonacci series till N numbers (which will be input through the user) using recursion.
4. C program to calculate power of a number using recursion.
   This program will read base and power and calculate its result using recursion, for example base is 2 and power is 3 then result will be (2^3=8).
5. C program to count digits of a number using recursion.
   This program will read an integer number and count its total digits using recursion, for example: input value is 34562, and then total number of digits is: 5.
6. C program to find sum of all digits using recursion.
   This program will read an integer number and print sum of all digits using recursion, for example: input value is 34562, and then sum of all digits is: 20.
7. C program to calculate length of the string using recursion.
   This program will read a string and count its total number of characters (length of the string) using recursion.
8. C program to reverse an integer number using recursion.
