Question

/* PROGRAMMING ASSIGNMENT 1:
Input: Enter five real numbers.
Output: Find the sum, product and relationship of each pair of numbers
e.g: input:
1,2,3,4,5
output:
The sum are:3,4,5,6,5,6,7,7,8,9
The products are:2,3,4,5,6,8,10,12,15,20
The relationship are:
1 < 2 1 < 3 1 < 4
1 < 5 2 < 3 2 < 4
2 < 5 3 < 4 3 < 5
4 < 5
