max int in c code example

Example 1: string to int c

atoi(str) is unsafe

This is the prefered method:
(int)strtol(str, (char **)NULL, 10)

Example 2: 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 3: how to print int in c

#include <stdio.h>
int main() {   
    int number;   
    printf("Enter an integer: ");  
    scanf("%d", &number);
    printf("You entered: %d", number);    
    return 0;
}

Example 4: max size for int c

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

Example 5: int max in c++

2147483647
  unsigned long long int = 18 446 744 073 709 551 615

Example 6: 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)
