Output
RUN 1
Enter 4 integer numbers
45
33
21
10
Input integer are
45   33   21   10

45 is the first largest
33 is the second largest

Average of 45 and 33 = 39

RUN 2
Enter 4 integer numbers
12
90
54
67
Input integer are
12   90   54   67

90 is the first largest
67 is the second largest

Average of 90 and 67 = 78

RUN 3
Enter 4 integer numbers
100
200
300
400
Input integer are
100  200  300  400

400 is the first largest
300 is the second largest

Average of 400 and 300 = 350
