C++ LLONG_MAX macro constant

LLONG_MAX constant is a macro constant which is defied in climits header, it is used to get the maximum value of a long long int object, it returns the maximum value that a long long int object can store, which is 9223372036854775807 (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 LLONG_MAX constant is defined in both of the libraries.

Syntax of LLONG_MAX constant:

    LLONG_MAX

Example:

    Constant call:
    cout << LLONG_MAX;

    Output:
    9223372036854775807

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

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

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

Output

LLONG_MAX: 9223372036854775807

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

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

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

Output

LLONG_MAX: 9223372036854775807
