Question

im trying to perform an index search for string, it runs but the problem is that it only prints out i[0] which is my first entry. if i lookup another entry it doesn’t work. Please help..
void clist(string fn[],string ln[], int size);

int search_list(const string fn[],const string ln[], int size, string find);

int main(){

    string search;

    cout << "This program searches a list .\n";

    const int total = 3;

    string fn[total];
    string ln[total];

    clist(fn,ln, total);

    cout << "Search contact:____  ";

    cin >> search;

    search_list(fn,ln, total, search);

  return 0;

}

void clist(string fn[],string ln[], int size){

    cout << "Enter " << size << " contact.\n";

    for (int index = 0; index < size; index++)
     cin >> fn[index] >> ln[index] ;

}

int search_list(const string fn[], const string ln[],int size, string search){

   for(int i=0;i<size;i++){

     if((fn[i] == search)&& (i < size)){

       cout<<"Result found "<<fn[i]<<" "<<ln[i]<<endl;

      break;

              }

    cout<<"no record found"<<endl;

     break;

    }

}

You are making a loop and explicitly telling it to break out of it after the first iteration. Try writting it like this:

bool found = false;
for(int i=0;i<size;i++){
 if(fn[i] == search){ // No need to check for(i < size)
   found = true;
   cout<<"Result found "<<fn[i]<<" "<<ln[i]<<endl;
   break;
 }
}

if(!found)
  cout<<"no record found"<<endl;
