Problem $1.$ Linear Search with an array.

Declare an one dimentional array of double type and initialize it using user input from the console. Then pass it by reference $($don$\text{'}$t forget passing the size also$)$ to the function int linearSearch$($double linstNum$[],$ int size, double target$\_$Item$)$ together with target$\_$item$($key$).$ The linear search function should return the index location of the item and print out the index in the console.
