代码没问题 怀疑是纯C环境 比较老的版本 所以要求变量定义只能在开头 你改成这样试试 include "stdio.h"#include "string.h"#define K_MAX_PATH 255int main(int argc,char * argv[]){char pszTempPathName[K_MAX_PATH],*p;FILE * fp;strcpy(pszTempPathName,argv[0]);p=strrchr(pszTemp...
string类型支持长度可变的字符串,C++标准库将负责管理与存储字符相关的内存,以及提供各种有用的操作。标准库string类型的目的就是满足对字符串的一般应用。 Aswith any library type, programs that usestringsmust first include the associated header. Our programs will beshorter if we also provide an appropriate...
