C++ SCHAR_MAX macro constant

SCHAR_MAX constant is a macro constant which is defied in climits header, it is used to get the maximum value of a signed char object, it returns the maximum value that a signed char object can store, which is 127.

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 SCHAR_MAX constant is defined in both of the libraries.

Syntax of SCHAR_MAX constant:

    SCHAR_MAX

Example:

    Constant call:
    cout << SCHAR_MAX;

    Output:
    127

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

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

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

Output

SCHAR_MAX: 127

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

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

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

Output

SCHAR_MAX: 127
