how to increase the array size dynalically  and statically in c language
If by array, you mean a static array :

        int array[20];

then you can't increase its size.

For dynamic arrays, you can use realloc :

        int *array = (int*) calloc(20, sizeof(int));
        int *tmp = (int*) realloc(array, 40 * sizeof(int));
        if (!tmp) {
            /* error : memory increase failed !! */
        else {
            array = tmp;

Reference page for realloc :
