SCHAR_MIN constant with example in C++

C++ SCHAR_MIN constant: Here, we are going to learn about the SCHAR_MIN macro constant of climits header in C++.
Submitted by IncludeHelp, on May 01, 2019

C++ SCHAR_MIN macro constant

SCHAR_MIN constant is a macro constant which is defied in climits header, it is used to get the minimum value of a signed char object, it returns the minimum value that a signed char object can store, which is -128.

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_MIN constant is defined in both of the libraries.

Syntax

Syntax of SCHAR_MIN constant:

SCHAR_MIN

Sample Input and Output

Constant call:
cout << SCHAR_MIN;

Output:
-128

Example 1

C++ code to demonstrate example of SCHAR_MIN constant with climits header:

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

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

Output

SCHAR_MIN: -128

Example 2

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

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

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

Output

SCHAR_MIN: -128
