Can unsigned long int hold a ten digits number (1,000,000,000 - 9,999,999,999) on a 32-bit computer?

Additionally, what are the ranges of unsigned long int , long int, unsigned int, short int, short unsigned int, and int?

You can use the numeric_limits<data_type>::min() and numeric_limits<data_type>::max() functions present in limits header file and find the limits of each data type.

#include <iostream>
#include <limits>
using namespace std;
int main()
{
    cout<<"Limits of Data types:\n";    
    cout<<"char\t\t\t: "<<static_cast<int>(numeric_limits<char>::min())<<" to "<<static_cast<int>(numeric_limits<char>::max())<<endl;
    cout<<"unsigned char\t\t: "<<static_cast<int>(numeric_limits<unsigned char>::min())<<" to "<<static_cast<int>(numeric_limits<unsigned char>::max())<<endl;
    cout<<"short\t\t\t: "<<numeric_limits<short>::min()<<" to "<<numeric_limits<short>::max()<<endl;
    cout<<"unsigned short\t\t: "<<numeric_limits<unsigned short>::min()<<" to "<<numeric_limits<unsigned short>::max()<<endl;
    cout<<"int\t\t\t: "<<numeric_limits<int>::min()<<" to "<<numeric_limits<int>::max()<<endl;
    cout<<"unsigned int\t\t: "<<numeric_limits<unsigned int>::min()<<" to "<<numeric_limits<unsigned int>::max()<<endl;
    cout<<"long\t\t\t: "<<numeric_limits<long>::min()<<" to "<<numeric_limits<long>::max()<<endl;
    cout<<"unsigned long\t\t: "<<numeric_limits<unsigned long>::min()<<" to "<<numeric_limits<unsigned long>::max()<<endl;
    cout<<"long long\t\t: "<<numeric_limits<long long>::min()<<" to "<<numeric_limits<long long>::max()<<endl;
    cout<<"unsiged long long\t: "<<numeric_limits<unsigned long long>::min()<<" to "<<numeric_limits<unsigned long long>::max()<<endl;
    cout<<"float\t\t\t: "<<numeric_limits<float>::min()<<" to "<<numeric_limits<float>::max()<<endl;
    cout<<"double\t\t\t: "<<numeric_limits<double>::min()<<" to "<<numeric_limits<double>::max()<<endl;
    cout<<"long double\t\t: "<<numeric_limits<long double>::min()<<" to "<<numeric_limits<long double>::max()<<endl;
}

The output will be: Limits of Data types:

  • char : -128 to 127
  • unsigned char : 0 to 255
  • short : -32768 to 32767
  • unsigned short : 0 to 65535
  • int : -2147483648 to 2147483647
  • unsigned int : 0 to 4294967295
  • long : -2147483648 to 2147483647
  • unsigned long : 0 to 4294967295
  • long long : -9223372036854775808 to 9223372036854775807
  • unsigned long long : 0 to 18446744073709551615
  • float : 1.17549e-038 to 3.40282e+038
  • double : 2.22507e-308 to 1.79769e+308
  • long double : 3.3621e-4932 to 1.18973e+4932
