Array of strings

There are 3 country names, find the first alphabetical string in the country

The code is as follows:

#include <iostream> #include <string>using namespace Std;int main () {    void smallest_string (char str[] 30],int i);//function declaration    int i;    Char country_name[3][30];//defines a two-dimensional character array, which has a two-dimensional character array as 3 one-dimensional character arrays, each of which has 30 elements for    (i=0;i<3;i++)    cin>> Country_name[i];    Smallest_string (country_name,3);    Call the Smallest_name function to pass the character array name to the parameter    return 0;} void Smallest_string (char str[][30],int n) {    int i;    Char string[30];    strcpy (String,str[0]);   Daleitai algorithm for    (i=0;i<n;i++)        if (strcmp (str[i],string) <0)        strcpy (String,str[i]);    cout<<endl<< "The smallest string is:" <<string<<endl;    }

Note: You can compare characters in any situation whenever you change some of the parameters of this function.
