Find if an element exists in C++ array - 


#include <iostream>  float x[10], k; int n, i;  cout<<"n= "; cin>>n;  (i=0; i<n; i++){     cout<<"x["<<i<<"]= ";     cin>>x[i]; }  cout<<"array's elements: "; (i=0; i<n; i++)     cout<<x[i]<<", ";  cout<<endl<<"k= "; cin>>k; for(i=0; i<n; i++)     if(x[i]!=k){         cout<<endl<<"k doesn't exist in array.";         cout<<endl<<"k= "; cin>>k;     }

i trying find if element exists in array, if doesn't exist want re-type element , repeat whole array , check it. mine doesn't start (i=0).

there standard function called std::find in header <algorithm>:

#include <iostream> #include <algorithm>  int main() {     int myarray[6]{10, 4, 14, 84, 1, 3};      if (std::find(std::begin(myarray), std::end(myarray), 1) != std::end(myarray))         std::cout << "it exists";     else         std::cout << "it not exist";     return 0; }
