Which part of this code C++ I’m missing where I need to convert a whole word to lowercase?

#include <iostream>
#include <stdio.h>
#include <stdlib.h>
#include <string>
#include <ctype.h>


using namespace std;

int main(){

   string nome = "Pedro";

   int tam = nome.size();

   int i;

        for(i = 0 ; i < tam ; i++){
            cout << tolower(nome[i]);
        }

    return 0;
}

Besides the precise disorganized code means you want a letter and not a number because according to the documentation that’s what the function tolower() results by default.

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

int main() {
    string nome = "Pedro";
    int tam = nome.size();
    for (int i = 0 ; i < tam ; i++) cout << tolower(nome[i], locale());
}

But if you want to use modern C++ :

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

int main() {
    for (auto letra : "Pedro") cout << tolower(letra, locale());
}

Behold working in the ideone. And in the repl it.. Also put on the Github for future reference.
