C语言实现字符串逆序
一、概述
案例:使用C语言实现字符串的逆序,用数组和指针两种方式实现。
二、代码示例
#include <iostream> #include <string.h> using namespace std; //字符串逆序,数组实现 void reserveStr(char *src,char* result){ size_t count = strlen(src)-1; int j = 0; for(int i = count;i>=0;i--){ result[j] = src[i]; cout << "result:"<<result[j]<<" src:"<<src[i]<<endl; j++; } result[j]='\0'; } //字符串逆序,指针实现 void reserveStr2(char* src ,char* result){ char * start = src; char *end = src+strlen(src)-1; while(end>=start){ *result = *end; result++; end--; } } int main(int argc, char const *argv[]) { char * src =(char*)"my babay is luoluoyang"; char* result; cout <<"src:"<<src<<endl; reserveStr2(src,result); cout <<"result:"<<result<<endl; return 0; }
