Calculate and display the highest and lowest percentage obtained.
Then display all percentages that are equal to or more than the average.
Lastly,display all 10 values entered by the user together with their letter grade values,one percentage and letter grade per line.

Create array of structure for students to store 40 student details. The

student structure should contain studid , studname, mark1, mark2

and mark3. Compute grade based on subject mark, The criteria for

grade is sample for mark1

< 50 grade = ‘F’

50 to 59 grade = ‘D’

60 to 69 grade = ’C’

70 to 79 grade = ‘B’

80 to 89 grade = ‘A’

90 to 100 grade = ‘S’

These grade has to be computed for 40 students and the entire array

of structure is copies to the file T1.Txt using fwrite() command. and

the content from the file T1.txt is read using fread() and all student

information’s are displayed in the system.

The address of memory location num1 and num2 are passed to function and the pointers *a and *b accept those values. So, the pointer a and b points to address of num1 and num2 respectively. When, the value of pointer is changed, the value in memory location also changed correspondingly. Write a program to swap the values in num1 and num2 using *a and *b. Use + and - operator for swapping
