Need help returning an index of a vector

[Danky]

Ok so what this does is puts in crimes of non violent, violent, and domestic crimes. Part of this is finding the max and min each and then print out the name of the city that has the highest and lowest of that crime.
example:
Highest Nonviolent Crime: Downtown
Lowest Nonviolent Crime : Canton
Highest Violent Crime: Downtown
Lowest Violent Crime: Canton
Highest Domestic Crime: Downtown
Lowest Domestic Crime: Canton
My problem is I can pass the information and find the max and min but I do not know how to get the index back for the city name.

The function I need help with is at the bottom of the page called findmaxmin and I will call it at the end of my main

  #include <iostream>
#include <fstream>
#include <iomanip>
#include <vector>
#include <sstream>

    int index;
    vector<string> District;

    vector<int> Violent_crime;
    vector<int> domestic_violence;

        return 0;
    }

    numDistrict.str(argv[2]);
    int num;

The trick is to save the index to the max and min values rather than the max and min values directly.
Adapting from your code:

void findmaxmin (const vector<string> &districtname,const vector<int> &crime){
    bool first = true;
    int maxIdx, minIdx, i;
   
    for(i = 0; i < districtname.size(); i++){
        if(first==true){
            maxIdx = 0;
            minIdx = 0;
            first = false;
        }else if(crime[i]>crime[maxIdx]){
            maxIdx=i;
            
        }else if (crime[i]<crime[minIdx]){
            minIdx=i;
        }
            
        
    }
//this is where I want to print out the max and min cities from above.
      cout << "lowest crime is " << crime[minIdx] << " in district " << districtname[minIdx] << endl;
      cout << "highest crime is " << crime[maxIdx] << " in district " << districtname[maxIdx] << endl;
    
}

THANK YOU SO MUCH!!!!!!!!!!!!
