Write a C program that calculate the grading system in an academic institution.

Problem Name: Write a C program that calculate the grading system in an academic institution

Algorithm:

Step 01: Start

Step 02: Input mark

Step 03: if (mark>79) output “grade=A+”

Step 04: else if (mark>74) output “grade=A”

Step 05: else if (mark>69) output “grade=A-”

Step 06: else if (mark>64) output “grade=B+”

Step 07: else if (mark>59) output “grade=B”

Step 08: else if (mark>54) output “grade=B-”

Step 09: else if (mark>49) output “grade=C+”

Step 10: else if (mark>44) output “grade=C”

Step 11: else if (mark>39) output “grade=D”

Step 12: else output “You are FAIL”

Step 13: End

C Program:

#include <stdio.h>

int main ()

{

int mark;

printf ("Enter your mark: ");

scanf ("%d", &mark);

if ( mark>=80 && mark <=100)

{

printf ("Your Grade is A+");}

else if ( mark>=75 && mark <80)

printf ( "Your Grade is A");

else if ( mark>=70 && mark <75)

printf ( "Your Grade is A-");

else if ( mark>=65 && mark <70)

printf ( "Your Grade is B+");

else if ( mark>= 60&& mark <65)

printf ( "Your Grade is B-");

else if ( mark>=55 && mark <60)

printf ( "Your Grade is C+");

else if ( mark>=50 && mark <55)

printf ( "Your Grade is C");

else if ( mark>=45 && mark <50)

printf ( "Your Grade is D");

else

printf("Your Grade is F");

return 0;
