Maximum Value Of Signed Char in C++

Maximum Value Of Signed Char in C++

Maximum Value Of Signed Char in C++. In this tutorial, we will discuss the signed char data type in C++.

In this article, we will discuss the signed char data type in C++.

Some properties of the signed char data type are:

  • It is generally used to store 8-bit characters.
  • Being a signed data type, it can store positive values as well as negative values.
  • Size of 8 bits is occupied where 1 bit is used to store the sign of the value.
  • A maximum value that can be stored in a signed char data type is typically 127, around 27 – 1 (but is compiler dependent).
  • The maximum and minimum value that can be stored in a signed char is stored as a constant in climits header file and can be named as SCHAR_ MAX and SCHAR_MIN respectively.
  • A minimum value that can be stored in a signed char data type is typically -128, i.e.around –27 (but is compiler dependent).
  • In case of overflow or underflow of data type, the value is wrapped around. For example, if -128 is stored in a signed char data type and 1 is subtracted from it, the value in that variable will become equal to 127. Similarly, in the case of overflow, the value will round back to -128

C++ Data Type Example | Data Types in C++ Tutorial

C++ data type is an inbuilt keyword that defines a type of the variable. If we want to declare an integer type data type, then we have to write int number.

Learning C: Input and Output and Two Program Templates

Learning C: Input and Output and Two Program Templates. Besides demonstrating how to perform input and output in C, I will also be demonstrating two templates that are related to those topics — Prompt, Then Read and Input, Process, Output (IPO). The IPO template, in particular, is important because practically every C program you write will use this template.
