Use:

#include
#include

std::string intToString(int num);

int main()
{
    int integer = 4782151;

    std::string integerAsStr = intToString(integer);

    std::cout << "integer = " << integer << std::endl;
    std::cout << "integerAsStr = " << integerAsStr << std::endl;

    return 0;
}

std::string intToString(int num)
{
    std::string numAsStr;

    while (num)
    {
        char toInsert = (num % 10) + 48;
        numAsStr.insert(0, 1, toInsert);

        num /= 10;
    }
    return numAsStr;
}
