gdb带参数调试方法

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
