We have given the input string as “maple” to the reverse string program, and the program then returned in the output the reverse string as “elpam.” Example # 02 We will now again implement the example for the reverse string, but this time, we will be using another method for string...
// Reverse a string in place. Use pointers rather than array indexing. void revstr_p(char *str) { char t; char *inc_p = str; char *dec_p = &str[strlen(str)-1]; while(inc_p <= dec_p) { t = *inc_p; *inc_p++ = *dec_p; *dec_p-- = t; } } void revstr_recursive...

Approach 6 – Using two pointers Conclusion One of the most common JavaScript interview questions is asking how to reverse a string. This would test your understanding of programming logic and also help you develop your concepts by learning how to solve one problem in various ways. There are ma...
First Capital letter is: A RUN 3: Enter string: www.includehelp.com Capital letter is not found in the string ExplanationIn the main() function, we read the value of string str from the user. Then we found the first capital letter in the string without using recursion and printed t...
// reverses text in between two pointers void Reverse(char *c1, char *c2) { while(c1 < c2) { char ch = *c1; *c1++ = *c2; *c2-- = ch; } } // reverses the complete string void Reverse(char *str) { if (!str) return; printf("'%s' ===> ", str); if(strlen(str) >...
Reverse string: nohtyP Flowchart: For more Practice: Solve these Related Problems: Write a C++ program that reverses a string using recursion without any library functions. Write a C++ program to reverse a string by swapping its characters in-place using two pointers. ...
const_pointer A type that provides a pointer to a const element in a string. const_reference A type that provides a reference to a const element stored in a string for reading and performing const operations. const_reverse_iterator A type that provides a random-access iterator that can read...
