例子:
#include <stdio.h>
int main(int argc,char *argv[])
{
int i = argc;
printf("argc:%d\n",i);
for(i = 0;i < argc;i++)
printf("argv[%d]:%s\n",i,argv[i]);
return 1;
}
输出:
[root@(none) ~]# gcc -g -o main main.c
[root@(none) ~]# ./main a b c
argc:4
argv[0]:./main
argv[1]:a
argv[2]:b
argv[3]:c
调试:
[root@(none) ~]# gdb main

或者用 r a b c也可以的
