Example of reverse string:-String: Know Program Reverse String: margorP wonK. 26, Jan 18. The algorithm for writing a C program for string palindrome is the same with only a single major difference: the function will keep calling itself recursively until the lower index is reverse(string, leftIndex, rightIndex) = swap(string, leftIndex, rightIndex) + reverse(string, leftIndex+1, rightIndex-1) Suppose, we want to reverse string "ORANGE" using recursion. Below is a program to reverse a user input string using recursion in C language. The substr() function is used to get a substring of the original string. First substring whose reverse is a word in the string. Until the end of the string is reached [] 2. first = 0; last = strlen(str)-1; b) In next step swap the position of character occur in first and last index. A given string can be reversed in the C language by using strrev function,without strrev, recursion, pointers, using another string, or displaying it in reverse order. Here more information. Thus,we will be continuously reducing the length of the string towards 0 which is our base case to return the string. Following are the various ways to find the reverse of a string in the C programming language: Reverse a string using the strrev () function Reverse a string without using the library function There are four ways to reverse a string in C, by using for loop, pointers, recursion, or by strrev function.
