C文件处理相关
1、main函数的两个参数
main函数中两个参数的含义
1 int main(int argc, char *argv[]) 2 3 { 4 5 ... 6 7 }
第一个参数argc是总共参数的个数（不包括自己）；
第二个参数*argv[]是输入参数，其中argv[0]是生成的.exe文件的地址，argv[1]是输入的第一个参数，以此类推。
如：
#include "stdafx.h" #include "stdio.h" #include "stdlib.h" int main(int argc, char* argv[]) { printf("%d\n",argc); printf("%s\n",argv[0]); printf("%s\n", argv[1]); return 0; }
输入：asds asf dd
输出：
4
C:\Users\samni\Desktop\TestError\TestError\Debug\TestError.exe
asds
