C++ square root calculator?

this is my code but it doesnt want to work right lol





its very basic


but if someone could help me i would appreciate it





#include %26lt;iostream%26gt;





using namespace std;





int main(void)


{


double dfirst;


double dsecond;


double dnum1;


double dnum2;


int answer;











{


cout %26lt;%26lt;"enter your first number" %26lt;%26lt; endl;


cin %26gt;%26gt; dfirst;


}





{


cout %26lt;%26lt; "enter your second number which needs to be less than the first"%26lt;%26lt; endl;


cin %26gt;%26gt; dsecond;


}


(dfirst / dsecond == dnum1);


(dsecond + dnum1 == dnum2);


(dnum2 / 2 == answer);





{


cout %26lt;%26lt; answer %26lt;%26lt; endl;





}





system("pause");


return 0;





}

C++ square root calculator?
ok , there is alil problem u ddnt notice may b , that :


in C , the symbol == is called the equlity operator. Recall that the symbol = is called the assignment operator.Remember that the eulity operator, == , determines where two expressoins are equal , that gives u a result of true or fales, only , but the assignment operator ,=, assigns the value of an expression to a variable. And all u need here is the assigmnemt operator not the equality one, so ur code is gonna be like:


# include %26lt;iostream%26gt;


using namespace std;


int main(void)


{


double dfirst;


double dsecond;


double dnum1;


double dnum2;


int answer;


{





cout%26lt;%26lt;"enter your first number"%26lt;%26lt;endl;


cin%26gt;%26gt;dfirst;


}


{


cout%26lt;%26lt;"enter our second number which needs to be less than the first"%26lt;%26lt;endl;


cin%26gt;%26gt;dsecond;


}





(dnum1=dfirst/dsecond);//16


(dnum2=dsecond+dnum1);//3


(answer=dnum2/2);





{





cout%26lt;%26lt;answer%26lt;%26lt;endl;


}





system ("pause");


return 0;


}





and ur square root calculater will work , enshallah.
