An integer in C int is represented by 4 bytes 1 byte 8 bits

An integer in C (int) is represented by 4 bytes (1 byte = 8 bits). Find the largest integer that can be handled by C. Verify that number by computer (try to printf that number, and printf that number+1). No programming is required for this.

Solution

In C size of int

Min: -2147483648
Max: 2147483647

So for your first question Find the largest integer that can be handled by C
Answer would be 2147483647

You can verify by the value by Executing below line of code

#include <stdio.h>
#include <limits.h>

^{int main()
{
   printf(\"The minimum value of INT = %d\ \", INT_MIN);//it will print -2147483648
    printf(\"The maximum value of INT = %d\ \", INT_MAX);//it will print 2147483647}

^return(0);
}

now come back to your next question printf that number+1

printf(\"The maximum value of INT = %d\ \", INT_MAX+1);//it will print -2147483648(may depend it may also crash)

above line may print you the -2147483648 , yes min value of int or some times program can crash.

Reason:this operation invokes undefined behavior. Signed integer overflow is undefined behavior in C.

For best practise Do not let portable program compute this expression.

Output:

The minimum value of INT = -2147483648
The maximum value of INT = 2147483647
The maximum value of INT+1 = -2147483648
