Question $6$

Why should programmers avoid making the following comparison with double $x?$

$x==0\mathrm{.}3$

Because variables should not be compared with literals

Because the $0\mathrm{.}3$ should come first: $0\mathrm{.}3=x$

Because doubles should not be compared with integers

Because $0\mathrm{.}3$ may not be exactly represented as $0\mathrm{.}3$

Given string str$1$ and string str$2,$ which expression is true?

str$1="$Hi$"$;

str$2=$ "Hello";

$str1str2$

str$1>$ str$2$

$($Comparison not possible$)$

str$1$ str$2$
