C++ int data type range
WebFeb 26, 2024 · The range of an integer variable is determined by two factors: its size (in bits), and whether it is signed or not. By definition, an 8-bit signed integer has a range of -128 to 127. This means a signed integer can store any integer value between -128 and 127 (inclusive) safely. As an aside… WebC++ Data Types. As explained in the Variables chapter, a variable in C++ must be a specified data type: Example. int myNum = 5; // Integer (whole number) ... int: 2 or 4 bytes: Stores whole numbers, without decimals: float: 4 bytes: Stores fractional numbers, containing one or more decimals.
