C++ program was resulting the value of 2 instead of 2.5 , what is the mistake ?
void main() {
intx = 5 ;
cout <<x/2 ;
}
Expert Answer
The variable x is declared to be of int type. So the division results in an int result. For a result to be fraction, atleast on of the 2 operands have to be float / double.
So you can change your code as
cout << x / 2.0;
Here 2.0 is a double , where as x is int. Since atleast one of the operands is double, hence the output of division will also be double.
The other way of getting the fractional part is to make x of type double;
void main()
{
double x = 5;
cout<< x / 2;
}
In this case, since x is a double, the output of division will be double.
Hope the answer helps. Please do not forget to rate the answer if it helped. Thank you very much.
