Question

Write a program for the following.

Create two arrays STP[ ] and STQ[ ], both of type int and size 8 and fill them with variables. Create a third array STUN[ ] that contains all the elements from both the arrays without any repetition.

For example:

Input	STP[ ]	17	54	36	87	44	92	28	77
Input	STQ[ ]	72	94	44	33	77	87	17	37
Output	STUN[ ]	17	54	36	87	44	92	28	77	72	94	33	37
