Question

What it the result of right shift of a negative integer in C

Answer 1

#include <stdio.h>

int main(void) 
{
    int n = -1;

    for (int i = 1; i <= 10; i++ )
    {
        int result = n >> 1;
        printf("%d\n", result);
    }
    
    return 0;
}

// C doesn't guarantee right-shift a negative signed number
    
/*
run:
 
-1
-1
-1
-1
-1
-1
-1
-1
-1
-1
