Answer:
We can use if-else statements to implement the given problem.
C++ Code:
#include <iostream>
using namespace std;
int main()
{
int marks;
cout<<"Enter the marks"<<endl;
cin>>marks;
if (marks>=90 && marks<=100)
{
cout<<"Grade: A"<<endl;
}
else if (marks>=80 && marks<=89)
{
cout<<"Grade: B"<<endl;
}
else if (marks>=70 && marks<=79)
{
cout<<"Grade: C"<<endl;
}
else if (marks>=60 && marks<=69)
{
cout<<"Grade: D"<<endl;
}
else if (marks>=0 && marks<=59 )
{
cout<<"Grade: F"<<endl;
}
else
{
cout<<"Invalid marks!"<<endl;
}
return 0;
