Further, it only requires the base address of the string as its argument and reverses the string accordingly. Let us see how we can use thestrrev()function inC++to reverse strings. #include<iostream>#include<cstring>usingnamespacestd;intmain(){charstr[]="Journal Dev reverse example";strrev(...
#include<iostream>#include<cstring>usingnamespacestd;intmain(){string s="abcd";strrev(s);cout<<s<<endl;return0;} 一般算法题中不能使用,因为不包含cstring。 函数(algorithm) #include<iostream>#include<string>#include<algorithm>usingnamespacestd;intmain(){string s="abcd";reverse(s.begin(),s....

printf("\nreverse of a string: %s ",strrev(string)); return0; } 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 ...
