Answer : 4

lets assume 10 stored at address = 100 ,

its array so continuous memory allocation . 

lets assume integer size = 4 Byte

then , 

10 20 30 40 50 60

100                    104                  108               112               116                120

p = (a+1) = 104  ,  q= (a+5) = 120

q-p = (120-104) = 16

we assumed size of INT = 4 Byte , so divide it by 4

so, q-p = 16/4 = 4
