字符串翻转
#include <iostream> using namespace std; //计算字符串长度 size_t str_len(char *str_source) { size_t i = 0; while (*str_source++ != '\0') { ++i; } return i; } //翻转 char* reverse_str(char* str_source) { size_t len = str_len(str_source); char* str_new = new char[len+1]; for (size_t i = 0; i != len; ++i) { str_new[i] = str_source[len-i-1]; } str_new[len]='\0'; return str_new; } int main() { char* str_sourec = "sdjakabc"; cout << reverse_str(str_sourec); }
