Write a program in C++to Evaluate the Performance of a Student Using if- else- if statement.

Here we discussed about the Performance of a Student using if-else-if  Statement. Here the difference Conditions are evaluated from the start and when a Condition is evaluated as true, the following Statements are executed and the rest of the Statements are skipped.

#include<iostream.h>

#include<conio.h>

void main()

{
clrscr();

float marks, percentage ;


cout<<"enter the marks scored out of 700 ";

cin>>marks;

percentage = (marks/700)*100;

if(percentage>=90 && percentage<=100)
 {
 cout<<"\n Grade A";
}
else if(percentage>=80 && percentage<90)
{
cout<<"\n Grade B";
}
else if(percentage>=70 && percentage<80)
 {
cout<<"\n Grade C";
}
else if(percentage>100)
{
cout<<"\n The marks you have enterd are incorrect";
 }
else
{
cout<<"\n Grade D";

        cout<<"\n you have got Grade D  which is equivlant to fail in marks system";
}

}


OUTPUT OF THIS PROGRAM GRADE BY GRADE WILL BE :
