Sample Output
n = 5
5
4
3
2
1
0

   
2. Write a C++ program to print out the reciprocal of the integers from 11 to 22. The output should be in the following format:

1/11 = 0.090909
1/12 = 0.083333
.......
   
3. Write a C++ program to input 6 integers and compute the sum of their squares.
   
4. Write a C++ program to return all the odd integers between m and n inclusively. The program should display at most 5 integers on each line of output.
   
5.
