3. 1. PSEUDOCODE
What is THAT ??
Pseudocode consists of short, English phrases used to explain specific tasks within a program's algorithm (The algorithm is a set of precise instructions specifying how to carry out a specific task.
Pseudocode should not include keywords in any specific computer languages. It should be written as a list of consecutive phrases.
You should not use flowcharting symbols but you can draw arrows to show looping processes.
Indentation can be used to show the logic in pseudocode as well.
One programmer should be able to take another programmer's pseudocode and generate a program based on that pseudocode.

4. Why PSEUDOCODE is necessary?
The programming process is a complicated one. You must first understand the program specifications, then organize your thoughts and create the program.
You must break the main tasks that must be accomplished into smaller ones in order to be able to eventually write fully developed code. Writing pseudocode WILL save you time later during the construction & testing phase of a program's development.

5. How to write PSEUDOCODE?
Make a list of the main tasks that must be accomplished on a piece of scratch paper.
Then, focus on each of those tasks, try to break each main task down into very small tasks that can each be explained with a short phrase. There may eventually be a one-to-one correlation between the lines of pseudocode and the lines of the code that you write after you have finished pseudocoding.

7. Example 1 – Program Specifications
Write a program that obtains two integer numbers from the user. It will print out the sum of those numbers.

8. PSEUDOCODE
Prompt the user to enter the first integer Obtain user's first integer input Prompt the user to enter a second integer Obtain user's second integer input Add first integer and second integer Store the result in another variable Display an output prompt that explains the answer as the sum Display the result

9. FLOW CHART Start Prompt user “Enter first integer” Read first integer
End
Prompt user “Enter first integer”
Prompt user “Enter second integer”
Display result of addition two integer numbers
Read first integer
Read second integer
Result =
First Integer +
Second Integer

10. Example 2 // example of if statements #include <stdio.h>
void main() {
int guess_input;
printf( “Please enter a whole number\n”);
scanf("%d",&guess_input);
if (guess_input==1)
printf( “Right number !\n”);
printf( "Well Done.\n” ); }

11. FLOW CHART FALSE Start Prompt user “Enter any number” Read a number
If number is 1
End
Prompt user “Enter any number”
Prompt user “Right number ! Well done!”
TRUE
FALSE
