My doubt is about the basic theory of "or logical operator". Especifically, logical OR returns true only if either one operand is true.

For instance, in this OR expression (x<O || x> 8) using x=5 when I evalute the 2 operands, I interpret it as both of them are false.

But I have an example that does not fit wiht it rule. On the contrary the expression works as range between 0 and 8, both included. Following the code:


#include <stdio.h>

int main(void)
{
    int x ; //This is the variable for being evaluated

    do
    {
    printf("Imput a figure between 1 y 8: ");
    scanf("%i", &x);

    }
    while ( x < 1 ||  x > 8 );  // Why this expression write in this way determinate the range???

    {
        printf("Your imput was ::: %d ",x);
        printf("\n");

     }
        printf("\n");

}



I really appreciate any helpo in order to clarify my doubt

In advance, thank you very much. Otto
