Thread: argv weirdness

Hi,

I'm experimenting with argv to learn more about how it works for a program I'm writing. I'm working with the code below:

Code:

#include<stdio.h>

int main( int argc, char **argv)
{
    char *array = argv[1];
    int i;
    printf( "%d\n", sizeof(array));
    for( i = 0; i < sizeof(array); i++ )
    {
        printf( "%c\n", array[i] );
    }
    return(0);
}

The thing that has me is the following behaviour:

[calef13@bluenode c]$ ./test1 127.0.0.1 1-20
4
1
2
7
.
[calef13@bluenode c]$

Can anybody here explain why it's stopping at the first 0? I can't for the life of me fathom it. But I suspect I'm doing something undefined. The code above works just fine for a second parameter "1-200". Also if there is a better way to get a string out of argv so it can be compared character by character, let me know.
