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; 80Explanation / Answer
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 , S2 , S3 , S4 ,S5 , S6 , per ;
clrscr ( ) ;
printf ( " Enter the marks " ) ;
scanf( " %d %d %d %d %d %d " , &S1 , &S2 , &S3 , &S4 ,&S5 , &S6 );
per = ( S1 + S2 ,+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
