Question

There was a exercise in my book, which asked me to write a for loop equivalent to :

for(i=0;(i<4) && (i<5);i++)

but without using && and || operator.

I came up with a solution like this :

for (i=0;;i++)
        if((i<4))
            if((i<5))
                printf("Works!!!\n");
            else
                break;
        else
            break;

It works. Since I’m a beginner in C, I want to know whether there are any better solution than this.

Thanks in advance.

Answer 1

Your && is combining two conditions such that one is a logically weaker one with respect to the other. If an integer is less than 4 it is necessarily less than 5. Thus (i<4) && (i<5) can just be replaced with (i<4).
