Let Us C (Chapter 8 : Arrays) : Program-8

(h) Write a program which performs the following tasks:
1) initialize an integer array of 10 elements in main( )
2) pass the entire array to a function modify( )
3) in modify( ) multiply each element of array by 3
4) return the control to main( ) and print the new array elements in main()
