range of int in cpp code example

Example 1: range of long long in c++

Long
Data Type	          Size             (in bytes)	Range
long int	            4	         -2,147,483,648 to 2,147,483,647
unsigned long int	    4	         0 to 4,294,967,295
long long int	        8	         -(2^63) to (2^63)-1
unsigned long long int	8	         0 to 18,446,744,073,709,551,615

Example 2: range of int

TypeName	Bytes	        Range of Values
  int		  4	    -2,147,483,648 to 2,147,483,647

Example 3: how to convert int in to const char in c

int size;
 char dispsize[100];
 sprintf(dispsize,"%d",size);

Example 4: converting char to int in c++

#include 

using namespace std;

int main()
{
    stringstream str;
    
    str << "1";

    double x;
    str >> x;
}
