Create a C program using ifelse statement Filename Input Out

Create a C program using if/else statement: Filename Input Output: homework_05a_lastnamefirstnameinitial. c: two variables A and B in double. Filename Input Output: print the biggest number among A and B, or if they are the same value, print the message to inform the user. Filename Input Output: homework_05b_lastnamefirstnameinitial.c: homework_05c_lastnamefirstnameinitial.c: a grade in number in double between 0 and 100.: one variable in integer: determine if the input is even or odd: print the grade in letter with this criteria: grade >=90 A; 80

Solution

2) even or odd

     # include < stdio.h >

    # include < conio.h >

    void main ( )

     {

           int n ;

           clrscr ( ) ;

           printf ( \" Enter a number : \" ) ;

           scanf ( \" %d \" , & n );

           if ( n % 2 == 0 )

                printf ( \" % d is even \" , n ) ;

             else

                printf ( \" %d is odd \" , n ) ;

               return 0 ;

}

   o/p -

    enter a number : 6

      6 is even

1) biggest number

   # include < stdio.h >

    int main ( )

    {

        float a , b ;

        clrscr ( ) ;

        printf ( \" Enter two numbers : \" ) ;

        scanf ( \" % f % f \" , &a ,&b ) ;

        if ( a > = b )

          {

              if ( b > = a )

                     printf ( \" largest number = %f \" , &a ) ;

       else

              printf ( \" largest number = %f \" , &b ) ;

         }

      else

        {

            if ( a == b )

               printf ( \" same number \" ) ;

           else

                return 0 ;

   }

}

o/p - enter two numbers : 25

30

largest number = 30.0000

enter two numbers : 25

25

same number     

3) student grading

    # include < stdio.h >

    # include < conio.h >

   void main ( )

   {

      int S₁ , S_{2 ,} S₃ , S₄ ,S₅ , S₆ , per ;

      clrscr ( ) ;

      printf ( \" Enter the marks \" ) ;

      scanf( \" %d %d %d %d %d %d \" , &S₁ , &S_{2 ,} &S₃ , &S₄ ,&S₅ , &S₆ );

       per = ( S₁ + S_{2 ,}+S₃ + S₄ +S₅ + S6 ) / 6 ;

       if ( per > = 90 )

         {

             printf ( \" A grade \" ) ;

         }

      else if ( per < 90 && per > = 80 )

         {

              printf ( \" B grade \" ) ;

         }

     else if ( per < 80 && per > = 70 )

        {

             printf ( \" C grade \" ) ;

        }

   else if ( per < 70 && per > = 50 )

        {

             printf ( \" D grade \" ) ;

        }

else if ( per < 50 && per > = 40 )

        {

             printf ( \" failed \" ) ;

        }

      getch ( ) ;

}

o/p

enter the marks -

92

94

96

97

91

90

result - A grade
