String array iteration causing segfault

I am populating an array of string and print it.
But it going in infinite loop and causing segfault.

Code:
char Name[][50] = {
                "yahoo",
                "rediff",
                "facebook",
                NULL
                };

main(int argc, char* argv[])
{
    int j = 0;

    while(Name[j] != NULL)
    {
            printf("j = %d    Name = %s    len = %d\n", j, Name[j], strlen(Name[j]));
            j++;
    }

    return(0);

}

output is
Code:
j = 0   Name = yahoo     len = 5
j = 1   Name = rediff len = 6
j = 2   Name = facebook       len = 8
j = 3   Name =     len = 0
j = 4   Name =     len = 0
j = 5   Name =     len = 0
j = 6   Name =     len = 0
j = 7   Name =     len = 0
j = 8   Name =    len = 0
j = 9   Name =    len = 0
.
.
.
12976 Segmentation fault      ./test_code

What is wrong with the code?
