I keep getting this error CS1529: A using clause must precede all other elements defined in the namespace except extern alias declarations. On the line of code (using System;) I highlighted in bold to tell the difference. this is a c# programming course I just started. I appreciate the help.
using System;
using align;
class Grades {
public static void Main(string[] args) {
const float MIDTERM_PERCENTAGE = .25F;
const float FINALEXAM_PERCENTAGE = .25F;
const float RESEARCH_PERCENTAGE = .30F;
const float PRESENTATION_PERCENTAGE = .20F;
int midterm = 70;
int finalExamGrade = 80;
int research = 90;
int presentation = 100;
float finalNumericGrade = 0;
finalNumericGrade =
(midterm * MIDTERM_PERCENTAGE) +
(finalExamGrade * FINALEXAM_PERCENTAGE) +
(research * RESEARCH_PERCENTAGE) +
(presentation * PRESENTATION_PERCENTAGE);
align. xyz abc = new align. xyz();
abc. disp("Midterm grade is : " + midterm);
abc. disp("Final Exam grade is : " + finalExamGrade);
abc. disp("Research grade is : " + research);
abc. disp("Presentation grade is: " + presentation);
abc. disp("\nThe final grade is: " + finalNumericGrade);
}
}
using System;
namespace align
{
class xyz
{
public void disp(string str)
{
Console. WriteLine(str);
}
}
}
