Question: write a program in C to add five 32 bit numbers available at successive memory locations and to divide the result by sixth numer available at next successive location.
Answer: main()
{ long int i, sum=0,*p;
p=1001; /* assume the numbers are from 1001 location */
for (i=0;i<5;i++)
{ sum= sum+ *p ;
p=p+1;
}
sum=sum/(*p) ; /* use only /*(p) not /*p since it may come to comment */
