you have an array with the type string. The second value is not a string
Peter87 (11178)
You are defining personlist to be an array of 10 arrays of 2 strings. 1, 2, ..., 10 are not strings.
Catfish3 (666)
string personlist[10][2]; means a multidimensional array of strings.

You can store 20 strings in it. Where exactly do you think you can store the integers 1, 2 ... 10? There's no place for them.

What you appear to want to do is:

#include <iostream>
#include <string>
#include <utility>

int main()
{
    std::pair<std::string, int> personlist[10] {
        {"person1", 1},
        {"person2", 2},
        {"person3", 3},
        {"person4", 4},
        {"person5", 5},
        {"person6", 6},
        {"person7", 7},
        {"person8", 8},
        {"person9", 9},
        {"person10", 10}
    };

    for (const auto &p: personlist)
        std::clog << p.first << ' ' << p.second << '\n';
}
 
person1 1
person2 2
person3 3
person4 4
person5 5
person6 6
person7 7
person8 8
person9 9
person10 10


Your compiler needs to be C++11 compliant to compile the above code.

Maybe it will be better to define the following array.
