Please, can someone help me in this exercise, because I really don't know too much about swaping!...

_____

Write the code that swaps the value of two int variables. Then round both variables to the nearest tenth. example: (If** x** contains the value of 43 and **y **the value of 87, then after the swap, the **x** should contain the value 87, and **y** the value 43. After rounding,** x** should contain a value of 90, and **y **the value of 40. )

THANK YOU!
