    You use the %d specifier when you call printf instead of %f.

    maybe because:
    Code:
    float v[10];
    /* ... */
    printf ("\n%d\n",v[imin]);
    Also use code tags and main returns an int

    Also, it's usually a safe thing but you can't always depend on your compiler to initialize a varaible to 0. It doesnt look like a problem here but is something good to know.
