Question

Code goes like:

#include <stdio.h>

/*
* askGrade():
* Asks the student for a letter grade
* (A = 90-100, B = 80-89, etc.)
* then gives the appropriate letter grade in upper case.
*/
void askGrade() {
int grade;
  
printf("Enter your grade:");
scanf("%d", &grade);
  
printf("Your grade is: ");
  
// BEGIN YOUR CODE
  
// TODO: Use if-else statements to print the right letter grade.
  
// END YOUR CODE
  
printf("\n");
}

/*
* dayOfTheWeek():
* Asks the student for a number, representing the day
* of the week (Monday = 1, Tuesday = 2, etc.),
* Then prints the name of the day.
*/
void dayOfTheWeek() {
int day;
  
printf("Enter the number of the day of the week:");
scanf("%d", &day);
  
printf("Today is ");
  
// BEGIN YOUR CODE
  
// TODO: Use switch statements to print the right letter grade.
  
// END YOUR CODE
  
printf("\n");
  
}

int main(void) {
// Call the first method
askGrade();
dayOfTheWeek();
return 0;
}

---------------------------------------------------------------------------

The objective of this exercise is to practice using conditionals

There are two sections of code you have to write, they are enclosed like this:

\\ BEGIN YOUR CODE

\\ TODO: Description of the task

\\ END YOUR CODE

The first section is in the askGrade() method. You have to use If-Else statements to check the range of a grade and assign it a letter grade:

• A = 90-100

• B = 80-89

• C = 70-79

• D = 60-69

• F = 0-59

• ERROR, otherwise

You only have to print out the right letter using printf().

----------------------------------------------------

The second section is in the dayOfTheWeek() method. You have to use a Switch statement to print out the right day of the week:

• Monday = 1

• Tuesday = 2

• Wednesday = 3

• Thursday = 4

• Friday = 5

• Saturday = 6

• Sunday = 7

• ERROR, for all other numbers

Answer 1

#include<stdio.h>
#include<conio.h>
void askGrade()
{
int n;
printf("enter the grade: ");
scanf("%d",&n);
printf("\n");
   if(n<=100 && n>=90)
   {
   printf("A");
   }
   else if(n<=89 && n>=80)
   {
   printf("B");
   }
   else if(n<=79 && n>=70)
   {
   printf("C");
   }
   else if(n<=69 && n>=60)
   {
   printf("D");
   }
   else if(n<=59 && n>=0)
   {
   printf("F");
   }
   else
   {
   printf("Error");
   }
printf("\n");
}
void dayOfTheWeek()
{
int d;
printf("enter the number: ");
scanf("%d",&d);
printf("\n");
switch(d)
{
   case 1:
   {
   printf("Today is Monday");
   break;
   }
   case 2:
   {
   printf("Today is Tuesday");
   break;
   }
   case 3:
   {
   printf("Today is Wednesday");
   break;
   }
   case 4:
   {
   printf("Today is Thursday");
   break;
   }
   case 5:
   {
   printf("Today is Friday");
   break;
   }
   case 6:
   {
   printf("Today is Saturday");
   break;
   }
   case 7:
   {
   printf("Today is Sunday");
   break;
   }
   default:
   printf("Error");

}
}
