C++ LONG_MIN macro constant

LONG_MIN constant is a macro constant which is defied in climits header, it is used to get the minimum value of a long int object, it returns the minimum value that a long int object can store, which is -9223372036854775808 (on 32 bits compiler).

Note:

• The actual value depends on the compiler architecture or library implementation.
• We can also use <limits.h> header file instead of <climits> header as LONG_MIN constant is defined in both of the libraries.

Syntax of LONG_MIN constant:

    LONG_MIN

Example:

    Constant call:
    cout << LONG_MIN;

    Output:
    -9223372036854775808

C++ code to demonstrate example of LONG_MIN constant with climits header

// C++ code to demonstrate example of 
// LONG_MIN constant with climits header
#include<iostream>
#include<climits>
using namespace std;

int main()
{
   //prinitng the value of LONG_MIN
    cout<<"LONG_MIN: "<<LONG_MIN<<endl;
    return 0;
}

Output

LONG_MIN: -9223372036854775808

C++ code to demonstrate example of LONG_MIN constant with limits.h header file

// C++ code to demonstrate example of 
// LONG_MIN constant with <limits.h> header file
#include<iostream>
#include<limits.h>
using namespace std;

int main()
{
   //prinitng the value of LONG_MIN
    cout<<"LONG_MIN: "<<LONG_MIN<<endl;
    return 0;
}

Output

LONG_MIN: -9223372036854775808
