C / C ++in <climits>(limits.h)

The header file "limits.h" exists in C language, while <climits> exists in C ++The language exists. Several macros are defined in these header files. The limits specify the values that a variable cannot store beyond the limits.

Some macros in the "limits.h" or <climits> header file are as follows

This is C ++Example of <climits> in the language,

Example

#include<iostream>
#include <bits/stdc++.h>
#include<climits>
using namespace std;
int main() {
　　　int x =　28;
　　　int a = CHAR_BIT;*sizeof(x);
　　　stack<bool> s;
　　　cout << "The number is : " << x << endl;
　　　for (int i=1; i <= a; i++) {
　　　　　　s.push(x%2);
　　　　　　x = x/2;
　　　}
　　　cout << "The number of bits in a byte : " << CHAR_BIT << endl;
　　　for (int i=1; i <= a; i++) {
　　　　　　cout << s.top();
　　　　　　s.pop();
　　　　　　if (i % CHAR_BIT == 0)
　　　　　　cout << " ";
　　　}
　　　cout << "\n\nThe minimum value of short int :" << SHRT_MIN;
　　　return 0;
}

Output Result

The number is :　28
The number of bits in a byte :　8
00000000 00000000 00000000 00011100
The minimum value of short int :-32768

In the above program, two macros from <climits> are represented. One is CHAR_BIT, and the other is SHRT_MIN. CHAR_BIT defines the number of bits in a char, while SHRT_MIN defines the minimum value of short int.

int x =　28;
int a = CHAR_BIT;*sizeof(x);
...
cout << "\n\nThe minimum value of short int :" << SHRT_MIN;
