Maximum value of short int in C++

21 Jun, 2022
In this article, we will discuss the short int data type in C++. This data type in C++ is used to store 16-bit integers.
Some properties of the short int data type are:
Being a signed data type, it can store positive values as well as negative values.Takes a size of 16 bits, where 1 bit is used to store the sign of the integer.A maximum integer value that can be stored in a short int data type is typically 32767, around 215-1(but is compiler dependent).The maximum value that can be stored in short int is stored as a constant in <climits> header file. Whose value can be used as SHRT_MAX.The minimum value that can be stored in short int is stored as a constant in <climits> header file. Whose value can be used as SHRT_MIN.A minimum integer value that can be stored in a short int data type is typically -32768 around (-215+1) (but is compiler dependent).In case of overflow or underflow of data type, the value is wrapped around. For example, if -32768 is stored in a short int data type and 1 is subtracted from it, the value in that variable will become equal to 32767. Similarly, in the case of overflow, the value will round back to -32768.

Below is the program to get the highest value that can be stored in unsigned long long int in C++: 
C++
// C++ program to obtain themaximum// value that can be store in short int#include <climits>#include <iostream>using namespace std; // Driver Codeint main(){    // From the constant of climits    // header file    short int valueFromLimits = SHRT_MAX;    cout << "Value from climits "         << "constant (maximum): "          << valueFromLimits << "\n";     valueFromLimits = SHRT_MIN;    cout << "Value from climits "         << "constant (minimum): "         << valueFromLimits << "\n";     // Using the wrap around property    // of data types     // Initialize two variables with    // -1 as previous and 0 as present    short int previous = -1;    short int present = 0;     // Increment both values until the    // present increases to the max limit    // and wraps around to the negative    // value i.e., present becomes less    // than the previous value    while (present > previous) {        previous++;        present++;    }     cout << "Value using the wrap "         << "around property :\n";    cout << "Maximum: " << previous << "\n";    cout << "Minimum: " << present << "\n";     return 0;}
Value from climits constant (maximum): 32767
Value from climits constant (minimum): -32768
Value using the wrap around property :
Maximum: 32767
Minimum: -32768
Time Complexity: O(N)Auxiliary Space: O(1)
