max value of int in c code example

Example 1: How to define Max in define in c

// For defining x > y
#define MAX(X, Y) (((X) > (Y)) ? (X) : (Y))
// For defining x < y
#define MIN(X, Y) (((X) < (Y)) ? (X) : (Y))

Example 2: max size for int c

-2,147,483,648 to 2,147,483,647

Example 3: c++ min int

int min = INT_MIN;

Example 4: C largest unsigned int

The sizeof function will help you here.
  sizeof(data type) returns a size_t //Number of bytes whatever the input for sizeof takes

Example:
//This statement will return 2 or 4 (depending on your system)
  return sizeof(int)
