Question
Find the errors in following program.
//This program uses a switch statement to assign a
// letter grade (A, B, C, D, or F) to numeric test score.
#include <iostream>
uisng namespace std;
int main()
{
int testScore;
cout<<"Enter your test score and I will tell you ";
cout<<"the letter grade you earned: ";
cin>>testScore;
switch (testScore)
{
case (testScore < 60)
cout<<"Your grade is F. ";
break;
case (testScore <70)
cout<<"Your grade is D. "
break;
case (testScore <80)
cout<<"Your grade is C. ";
break;
case (testScore < 90)
cout<<"Your grade is B. ";
break;
case (testScore <= 100)
cout<<"Yourgrade is A. ";
break;
default:
cout<<"That score isn't valid ";
return 0;
}
Explanation / Answer
1.) inplace of uisng, it should be using
2.) you can't use testScore in constant expression
3.) each case should be end with a colon
4.) there should be a semi-colon after statement
cout<<"Your grade is D. "
5.) a '}' is required to close the switch block
