problems with expressions

[sovan chatt]

 #include<stdio.h>
int main()
{int i=-3,j=2,k=0,m;
m=++i||++j&&++k;
printf("%d%d%d%d\n",i,j,k,m);
return 0;
}   

The output of the above code is -2 2 0 1
Why is this happening?I guess it should have been -2 3 1 1

++i||++j&&++k

++i is true, so the rest will not be evaluated. ++j, ++k will not be executed.

Expressions are evaluated from left to right in c++,
As ++i is true, right hand side of || will not get evaluated.

@rohan yadav,@Christophe Verré thanks...

Is that a general rule, or does it only apply to expressions separated by && and ||?

[rohan yadav]

I guess Left to right is general rule but i am not sure, I tried some generalized scenario's, i find left to right rule working properly,
But as i said i am not sure...

You would need to check the language specifications carefully; I know left-to-right is specified for Java, but I am not sure about C++.
