// input range to scan values


cin %26gt;%26gt; lowerx;


cin %26gt;%26gt; upperx;





// loop over all combinations of x and y


for (int x = lowerx; x %26lt; upperx; x++)


{


for (int y = lowery; y %26lt; uppery; y++)


{


if (!(x%26lt;5)%26amp;%26amp;!(y%26gt;=7) != !((x%26lt;5)||(y%26gt;=7))) // test equivalence


{


printf("Expressions are not equivalent. x = %d, y = %d", x, y);


return;


}


}


}





printf("Expressions are equivalent over the specified range");


return;

are you retarded? Do you have Suleyman? ;)





you never declared any of your upper or lower variables





you need your returns to be return(0);





and you're missing a '}' after the last return.
Reply:Good answer! Would be best, if you didn't call him retarded, though.





Use a syntax checker that will show you on which line something is wrong. Report It

Reply:Do you have "lowery" and "uppery" defined?
