Question

The code I have is like this:

#include <iostream>
#include <string>
#include <cstdlib>
#include <vector>
using namespace std;

int main() {
int i = 0;
const int NUM_VALS = 7;
vector<string> firstname(NUM_VALS);
vector<string> lastname(NUM_VALS);
string searchval;

for (i = 0; i < NUM_VALS; ++i) {
cin >> firstname.at(i);
cin >> lastname.at(i);
}

cin >> searchval;

for (i = 0; i < NUM_VALS; ++i) {
if (searchval == lastname.at(i)){
cout << firstname.at(i);
}
}

return 0;
}

Explanation / Answer

I dont understand why you are always reading 7 Times,

But looks like you are putting values into vector much more than its needed.

You can do a break and dont print it again, Looks like that could be the Problem .

=======================================================================================

#include <iostream>
#include <string>
#include <cstdlib>
#include <vector>
using namespace std;
int main() {
int i = 0;
const int NUM_VALS = 7;
vector<string> firstname(NUM_VALS);
vector<string> lastname(NUM_VALS);
string searchval;

for (i = 0; i < NUM_VALS; ++i) {
cin >> firstname.at(i);
cin >> lastname.at(i);
}

cin >> searchval;

for (i = 0; i < NUM_VALS; ++i) {
if (searchval == lastname.at(i)){
cout << firstname.at(i);
break;
}
}

return 0;
}

Let me know if it works, If not I can modify and not read input always 7 times as you are doing.
Thanks, let me know if there is anything.
