Question

Task 2) Write and execute a C program using any C compiler to input students' number of previous semesters attended and marks of all the modules he has studied. And do the following: a. Determine and display grade received for each module studied according to the following conditions: Condition Result Marks is greater than or equal to 91 A Marks is greater than or equal to 70 B Marks is greater than or equal to 50 D Otherwise F b. Write a switch-case statement for each module mark and display GPA according to the following: Module Grade GPA A 4 B 2 D 1 Otherwise 0 C. Calculate and display the CGPA which is average GPA of all the modules. d. With the same scenario as given in a,b,c and d do the following: 1) Pseudocode 2) Flowchart

Answer 1

Answer-a)

#include<stdio.h>
int main()
{
int marks; // variable marks
printf("Enter your marks ");
scanf("%d",&marks);
if(marks<0 || marks>100)
{
printf("Wrong Entry");
}
else if(marks<50) // marks is less than 50
{
printf("Grade of student is Fail");
}
else if(marks>=50 && marks<70) //marks is greater than 50 and less than 70
{
printf("Grade of student is D");
}
else if(marks>=70 && marks<91)//marks is greater than 70 and less than 91
{
printf("Grade of student is B");
}
  
else if(marks>=91 && marks<100)
{
printf("Grade of student is A");
}
return 0;
}
  
Output-
Enter your marks 92
Grade of student is A

Enter your marks 80
Grade of student is B

Enter your marks 55
Grade of student is D

Enter your marks 40
Grade of student is Fail

{ 9 1 #include<stdio.h> 2 int main() 3-{ 4 int marks; // variable marks 5 printf("Enter your marks "); 6 scanf("%d",&marks); 7 if(marks<0 || marks >100) 8- printf("Wrong Entry"); 10 } 11 else if(marks<50) // marks is less than 50 12. 13 printf("Grade of student is Fail"); 14 15 else if(marks >=50 && marks<70) //marks is greater than 50 and less than 70 16 17 printf("Grade of student is D"); 18 } 19 else if(marks >=70 && marks<91)//marks is greater than 70 and less than 91 20 21 printf("Grade of student is B"); 22 { } فهه Y { }

else if(marks >=91 && marks<100) { 23 24 25 26 27 28 29 } printf("Grade of student is A"); Y return 0; output- Enter your marks 92 Grade of student is A
Answer-b)

#include<stdio.h>
int main()
{ char grade;
printf("Enter Grade( A or B or D ): ");
scanf("%c",&grade);
switch( grade )
{
case 'A':
printf("GPA=4");
break;
case 'B':
printf("GPA=2");
break;
case 'D':
printf("GPA=1");
break;
default:
printf("GPA=0");
break;
}
return 0;
}
Output-
Enter Grade( A or B or D ): B
GPA=2

Answer-c)

4 8 1 #include<stdio.h> 2 int main() 3. { char grade; printf("Enter Grade A or B or D): "); 5 scanf("%c",&grade); 6 switch( grade) 7 { case 'A': 9 printf("GPA=4"); 10 break; 11 case 'B': 12 printf("GPA=2"); 13 break; 14 case 'D': 15 printf("GPA=1"); 16 break; 17 default: 18 printf("GPA=0"); 19 break; 20 21 return 0; 22 } } input Enter Grade A or B or D): B GPA=2

6 1 #include<stdio.h> 2 int main() 3. { int GPA1, GPA2, GPA3, GPA4; 4 float average; 5 printf("Enter GPA for grade A "); scanf("%d",&GPA1); 7 printf("Enter GPA for grade B "); 8 scanf("%d",&GPA2); 9 printf("Enter GPA for grade D "); 10 scanf("%d",&GPA3); 11 printf("Enter GPA forotherwise "); 12 scanf("%d",&GPA4); 13 average=(float) (GPA1+GPA2+GPA3+GPA4)/4; printf("CGPA=%f", average); 15 return 0; 16 14 } input Enter GPA for grade A 4 Enter GPA for grade B 2 Enter GPA for grade D 1 Enter GPA forotherwise 0 CGPA=1.750000

Answer-d)

1) Pseudocode for a)-

1. if(marks<0 || marks>100) then
2. display wrong entry
3. else if(marks<50)
4. result = "Fail" ' display "F"
5. else if(marks>=50 && marks<70)
6. result = "D" ' display "D"
7. else if(marks>=70 && marks<91)
8. result = "B" ' display "B"
9. else if(marks>=91 && marks<100)
10. result = "A" ' display "A"
11. End If

1) Pseudocode for b)-

1.Input a Grade
2.Case based on Grade
Case ='A'
display “GPA=4”
Case ='B'
display “GPA=2”
Case ='D'
display “GPA=1”
Default
display “GPA=0”
3.End Case

1) Pseudocode for c)-

1. Read GPA

2. Sum GPA.

3. Average=sum/4

4. Display Average

Answer-2)

Flowchart for a)

Flowchart for b)-

Flow chart start Read marks marks>=91 marks >=70 and <91 marks >=50 and <70 Display fail Display grade =A Display grade =B Display grade =D stop

enter grade true grade='A' GPA=4 false true grade='B' GPA=2 false true grade='D' GPA=1 false GPA=0

Flowchart of CGPA-

Flow chart start Read GPA Average Display CGPA stop
