c++ - Convert character array to int

Trying to convert a character array to int data type in c++11. Why is the int value i different than the character array value?

// Example program
#include <iostream>
#include <string>

int main()
{
    char value[] = "51093843802";
    printf("%s\n", value);
    int i = std::atoi(value);
    printf("%d\n", i);
}
