System.out.println(questions[a]);
System.out.println("A.True");

//result check switch(answer){
case 'A': if(answer==act_answers[a]) {
System.out.println("Correct!"); d++; }
else { System.out.println("The correct answer is "+act_answers[a]); }
break; case 'B': if(answer==act_answers[a]) {
System.out.println("Correct!"); d++; } else {
System.out.println("The correct answer is "+act_answers[a]); }
break; case 'C': if(answer==act_answers[a]) {
System.out.println("Correct!"); d++; } else {
System.out.println("The correct answer is "+act_answers[a]); }
break;
default:
System.out.println("Incorrect Input.Please Enter Only A B and C Choices. Thank you!");
break;
}
}
System.out.println("Number of correct answers are "+d);
percentage=(+d/10)*100;
System.out.println("Total Percentage is "+percentage+"%");
}
}
This program will not show the percentage. it only outputs 0.0
how do i fix this problem?
Explanation / Answer
Please change the statement
percentage=(+d/10)*100;
to
percentage=((float)d/10)*100;
Because 'd' is an int variable, (d/10) will produce an int value. So we have to explicitly convert 'd' into float. Then it will give the correct percentage
