1.使用string.h中的strrev函数 #include<stdio.h> #include<string.h> int main() { char s[]="hello"; strrev(s); puts(s); return 0; } strrev函数只对字符数组有效,对string类型是无效的。 1 2 3 4 5 6 7 8 9 10 11 12 2.使用algorithm中的reverse函数 #include <iostream> #include <...

l, and temporary_var, all having the same data type, “int.” We will call the strlen() function to take the length of the string that we had declared as the parameter of the function “reverse” passing this string to the arguments of strlen() we will get the length of the string...
Question 1.2 ofCracking the Coding Interview: Implement a functionvoid reverse(char* str)in C or C++ which reverses a null-terminated string. This is (implicitly) asking for an in-place reversal of the string. We start by finding the end of the string (or equivalently, its length). Then...
C String function – strlen Syntax: size_tstrlen(constchar*str) size_trepresents unsigned short It returns the length of the string without including end character(terminating char ‘\0’). Example of strlen: #include<stdio.h>#include<string.h>intmain(){charstr1[20]="BeginnersBook";printf(...
