Assume $"$x$"$ is an integer variable. Consider the following two if$-$statements

$1.$ if$($x $==0)\{$ cout $<<"$X is zero" $<<$ endl; $\}$

and

$2.$ if$($x $=0)\{$ cout $"$X is zero" $<<$ endl; $\}$

What is the difference between statement$-1$ and statement$-2?$

Your answer

Which one of those is an incorrect way to define an if$-$statement?
