std1 = 87;

std2 = 90;

std3 = 67;

std4 = 72;

std5 = 78; // as grades of five students

avegrade = 0;

Write a program to perform the following tasks.

I. declare and initialize std1, std2, std3, std4, std5, and avegrade as above.

II. compute the average grade of the five students and assign it to avegrade, and then display the

average grade on the screen.

III. Using if else statement:

If the avegrade is >= 80, display message A level on the screen.

If the avegrade is >= 60 and < 80, display message B level on the screen.
