Sos, plz solve the errors c++(core)?

#include%26lt;iostream.h%26gt;


#include%26lt;conio.h%26gt;


main()


{


float a,b,sign;


cout%26lt;%26lt;"enter two numbers";


cin%26gt;%26gt;a%26gt;%26gt;b;


cout%26lt;%26lt;"choose a sign";


cin%26gt;%26gt;sign;


if (sign==1)


{sign=a*b;


cout%26lt;%26lt;sign;}


if (sign==2)


{sign=a+b;


cout%26lt;%26lt;sign;}


if (sign==3)


{sign=a/b;


cout%26lt;%26lt;sign;}


if (sign==4)


{sign=a-b;


cout%26lt;%26lt;sign;}


getch()


}


}

Sos, plz solve the errors c++(core)?
what kind of math is that??????????


ummmmmmm.................................


dont know sorry

// Note : you can remove cout%26lt;%26lt;flush; it forces the cout to write on the screen before the pause caused by getch();
Reply:Unless you can be more specific regarding an error (logical) ... as I do not understand the intent of the code other than the obvious ... there are two syntax errors :





(1) Missing semicolon after "getch()"





(2) An excess brace after the line mentioned above.





I would also clean up the code by using a simple switch statement and a few other minor adjustments, as follows :





#include %26lt;conio.h%26gt;


#include %26lt;iostream.h%26gt;





void main()


{


float a, b, result;


int operator;





cout %26lt;%26lt; "Enter two numbers :";


cin %26gt;%26gt; a;


cin %26gt;%26gt; b;





cout %26lt;%26lt; "Select an operator.";


cout %26lt;%26lt; "1. Multiplication";


cout %26lt;%26lt; "2. Addition";


cout %26lt;%26lt; "3. Division";


cout %26lt;%26lt; "4. Subtraction";


cin %26gt;%26gt; operator;





switch (operator)


{


case 1 :


result = (a * b);


break;





case 2 :


result = (a + b);


break;





case 3 :


result = (a / b);


break;





case 4 :


result = (a - b);


break;


}





cout %26lt;%26lt; "Result = " %26lt;%26lt; result;





getch();


}
