( Functions ) I
The problem tasks are divided into sub-tasks. In FORTRAN each sub-task can be implemented as a separate module called FUNCTION or SUBROUTINE.
Type: type of return value (INTEGER , REAL...) returns by the function
list of arguments: zero or more arguments passed to the function
Write a logical function TRINGL that checks whether three given angles (in degrees) form a triangle or not. Write a main program that reads three angles from the input and uses the function TRINGL to output one of the following messages: ANGLES FORM A TRIANGLE or ANGLES DO NOT FORM A TRIANGLE accordingly .
Write a main program, which reads the radius of a circle. Then it calls a real function called AREA to compute the area of a circle (pr2). The main program should print the result.
Note: PI = 3.14159
A function f (x, y) is defined as:
ì (x2+ y2 ) / (x - y) if x ≠ y
f(x,y) = í
î 2x2 + y + 3 if x = y
Write a main program to read X and Y and print the value of f(X,Y). The value should be computed by a function subprogram invoked by the main program.
Test your program with the following data:
4. 0 2 .0
6. 5 3. 5
2 . 0 7. 0
