UNIPORT CSC 280: Answers to Introduction to Computer Programming (Modern FORTRAN) Practical Workbook Part III

CSC 280 Answers to Practical Workbook – Introduction to Computer Programming, Modern FORTRAN Language Programs – CSC 280 is a course from Department of Computer Science, Faculty of Science in the University of Port Harcourt as well as other Universities. It is offered as borrowed course by other departments to enable them have the knowledge of programming. Though, it was introduced to the University as GES 101 – Computer Appreciation and Application.

In this course, ForTran – Formula Translator language is obeyed. Students are expected to run the programmes using Plato FORTRAN Application.

The objective of the course is that, students will learn how to run programmes on their own before semester ends. Thus, the initiation of the course in the University.

To pass this course is very easy as you are very lucky to come across this article. You must fill your manual or workbook very well. You can use download the PDF of the ones we have filled to fill yours. Also, you are required to do well in your Test then your exams.

Lab 25: Reading an Array 1

Algorithm

1. Declare all variables
2. Supply value less than 10 to n
3. Do i = 1, n

Supply values to array X

End do

4. Print the values each that has stored in array X

Observations/Output

Observation: The program declares one dimensional array called a size that is less than or equal to and stores random integer values. The array depending on the size of the array.

Output:

Let n = 3

40

10

60

Lab 26: Reading an Array 2

Algorithm

1. Declare all variables
2. Declare the size of the array
3. Supply values to the array using a shorthand form
4. Display the values stored in the array

Observations/Output

Observation: In the program and their form of supplying values to arrays was used instead of the usual do loop

Output:

Let n = 3

40

10

60

Lab 27: Reading values into a Matrix

Algorithm

1. Declare all variables including the two-dimensional array
2. Supply values to ml and n1
3. Supply values to elements of two-dimensional array
4. Display result of the elements stored in the two-dimensional array.

Observations/Output

Observation: The name of the program is Matrix. A constant variable with value is declared as integer. (i.e. max = 5). A nested do loop is used in the program to supply values to a two-dimensional array and to display the values stored in the array.

Output:

If m1=2, n1 = 2

4

6

0

3

Lab 28: Sorting –Bubble Sort

Aim: Write a program to sort the elements of an array using bubble sort algorithm.

ALGORITHM

1. Declare variables and array
2. Enter the total number to be sorted
3. Supply values to be sorted
4. Sort the element of the array

OBSERVATION/OUTPUT

Observation: the name of the program is sort and it sorts numbers in ascending order. An array called list was declared with maximum size of 100. After values have been supplied to the array then the program sort the values in ascending order.

Output: if actualize = 2, then, the operation will be carried out. We may have

33        40

As the output if we supply 40 and 33 as the elements of the array lists.

Functions, subroutines and data transfer
