What will be printed to the standard output when the following C program is exe- cuted? #include int main()[ int v1 = 12; int a[] {7,8,10,2,22, 15 } ; int *p2-a; int v2 = *p1 + *(p2+3) + v1; p2++ p1 = p2 + 5; printf("%d,Ja,..*d,Ja, Jdin'' , v1, v2, *p1, *p2, (int ) p2 ); State that the value is unknown if it is not possible to determine an exact value by just inspecting the program code.
