#include <stdio.h>

int main()
{
    int i;
    for(i=0; i<10; i++)
    {
        printf("%d\n",i);
    }

    return 15;
}

gcc -o a a.c

如何在shell脚本中接收a的返回值呢

You can get the retrun value by using $? after you execute the 'a' program

before I asked the question, I have tried the method you mentioned, it have  no use.

-bash-3.00$ cat a.c
#include <stdio.h>

int main()
{
    int i;
    for(i=0; i<10; i++)
    {
        printf("%d\n",i);
    }

    return 15;
}
-bash-3.00$ gcc -o a a.c
-bash-3.00$ ./a

Thanks for your reply, I have test the program on a backup machine, it works!

there must be something wrong with my host. it feedbacks me a '0' value after I executed command "./a"
