Question

C语言编写的时候构建有什么用，为什么我写的这个程序构建之后，就出现逻辑错误。程序没问题吧？

#include "time.h"#include <stdio.h>#include "stdlib.h"#include "string.h"#define XINXI 2main(){ char LY[5] = "leiyi"; char PN[4] = "puni"; int leiyi[XINXI] = {2,3}; int pini[XINXI] = {3,4}; char playerTypeInformation[100] =""; gets(playerTypeInformation); if (strcmp(playerTypeInformation,"LY")==0) printf ("玩家输入的精灵是雷伊"); else if (strcmp(playerTypeInformation,"PN")==0) printf ("玩家输入的信息是谱尼"); else printf ("玩家输入的信息不存在");}这是源代码，下图是，未构建直接运行的情况，构建之后运行就显示的是“玩家输入的信息不存在”

char LY[5] = "leiyi"侍凯烂;
char PN[4] = "puni";
上面两句错了，应该改为
char LY[6] = "leiyi";
char PN[5] = "puni";

字符串是特殊老漏的数组，末尾会自动填入/孙慎0
