Hi,

well i have a userinput for an integer. And i have to get sqrt of that number and find the closes number from array... and i dont rly know how to do that... can anyone help?

heres the part for my input:

and here's the function i use to fill in the array with prime numbers,.. etc...so this function also has to return the closest number from the array to the sqrt of the inputed integer...Code:int poljubnostevilo; cin >> poljubnostevilo; cout <<endl; int koren = sqrt (poljubnostevilo); cout << koren << endl;

Hope anyone can help meCode:int funkcijatri(int x, int n){ n = 4; int praarray[x]; int a=0; int sum; while(a<x){ n++; if(IsPrime(n) && (n>=a)){ praarray[a] = n; cout << praarray[a] << ", "; sum+= praarray[a]; a++; }//konec if }//konec while return sum/x; }
