About c++ (if and else)?

there is an error saying "illegal else without matching if"


how will i correct this one?





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


int main ()


{


// conditional statement


int age;


cout%26lt;%26lt;"Enter your age:";


cin%26gt;%26gt;age;


if(age%26lt;16)


cout%26lt;%26lt;"you are highschool.....";


cout%26lt;%26lt;endl;


else(age%26gt;16)

you dont need the else(age %26gt; 16), else means its going to be executed if the if statement is false and also you need





if(condition){





}else{





};








the { } are necessary is you have more than one line of code between if and else





if( condition)


one line


else


one line





is legal
Reply:You forgot the braces.





A if else statement's sytax is


if()


{





}else{





}





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


int main ()


{


// conditional statement


int age;


cout%26lt;%26lt;"Enter your age:";


cin%26gt;%26gt;age;


if(age%26lt;16)


{


cout%26lt;%26lt;"you are highschool.....";


cout%26lt;%26lt;endl;


}


elseif(age%26gt;16)


{


cout%26lt;%26lt;"Maybe you are college";


cout%26lt;%26lt;endl;


return 0;


}
Reply:if statements go like this





if (some conditional)


some expression


else


some expression





remember that to group a collection of expressions you need to put in { and }





so to make a BLOCK of code





if (some condition)


{


some code


some more code


}


else


{


even more code


a lot more code


}
Reply:You have two statements in the if block without curly braces.





if(age%26lt;16)


cout%26lt;%26lt;"you are highschool.....";


cout%26lt;%26lt;endl;


else(age%26gt;16)


cout%26lt;%26lt;"Maybe you are college";


cout%26lt;%26lt;endl;





should be:





if(age%26lt;16)


{


cout%26lt;%26lt;"you are highschool.....";


cout%26lt;%26lt;endl;


}


else(age%26gt;16)


{


cout%26lt;%26lt;"Maybe you are college";


cout%26lt;%26lt;endl;


}
Reply:try this:





int main ()


{


// conditional statement


int age;


cout%26lt;%26lt;"Enter your age:";


cin%26gt;%26gt;age;


if(age%26lt;16)


cout%26lt;%26lt;"you are highschool.....";


cout%26lt;%26lt;endl;


else


if(age%26gt;16)


cout%26lt;%26lt;"Maybe you are college";


cout%26lt;%26lt;endl;


return 0;


}
Reply:one line expression:





if()


... ;


else

more than one line expression:





if(){

}


else{

}








if(){
