Hey there!

Could you please format your code within [ c o d e] [ / c o d e ] (w/o spaces) tags?

Also, srand(unsigned(0)); should be srand(time(0));.

Are you sending the entire array to the function or are you just sending one element of the array? The prototype says it's getting a single integer value but the actual function definition says it's getting an array.

int find(const int , int ,int);//function

int find(const int Array[], int ArraySize, int ItemToSearch)//function

i am sending the entire array.
