C++ String crend()The crend() function stands for reverse end. It points to the first character of string and returns constant reverse iterator. SyntaxConsider a string s. Syntax would be: const_reverse_iterator itr=s.crendO; ParameterIt does not contain any parameter. Return valueIt returns a constant reverse iterator to the reverse end of the string. Example 1Let's see a simple example. #include<iostream> using namespace std; int main() { string str="C Programming"; for(string::const_reverse_iterator itr=str.crbegin();itr!=str.crend();++itr) cout<<*itr; return 0; } Output: gnimmargorP C In this example, we got the reverse string using crend() function. Example 2Let's see another simple example. #include<iostream> using namespace std; int main() { string num="12345"; for(string::const_reverse_iterator itr=num.crbegin();itr!=num.crend();++itr) cout<<*itr; return 0; } Output: 54321 In this example, we got the reverse string containing integer values using crend() function.
