Question

Write a program for the following.

Create two arrays TEC[ ] and TEH[ ], both of type int and size 8 and fill them with variables. Create a third array TIN[ ] that contains only the common elements of both the arrays.

For example:

Input	TEC[ ]	17	54	36	87	44	92	28	77
Input	TEH[ ]	72	94	44	33	77	87	17	37
Output	TIN[ ]	17	87	44	77
