    {
        printf("\n C Grade");
    }
    else if(marks>=40 && marks<=49)
    {
        printf("\n D Grade");
    }
    else if(marks>=0 && marks<=39)
    {
        printf("\n F Grade");
    }
    else
    {
        printf("\n Invalid input");
    }
    return 0;
}

Output:

 











If you are using Turbo C++ IDE, then use conio.h in link section after stdio.h
and use getch(); to hold the output screen, just before the end of main function.
If you have any confusion regarding the program, please, comment below.
Happy Coding !
Thank you
