Algorithm And Flowchart Lecture 1
The main purpose of a flowchart is to analyze different processes.
Algorithm and flowchart lecture 1. Lectures by walter lewin. Add to sum 7. Algorithms are nothing but sequence of steps for solving problems. With algorithms we can easily understand a program.
But before actually writing a program in a programming language a programmer first needs to find a procedure for solving the problem which is known as planning the program. A programmer uses various programming languages to create programs. The final grade is calculated as the average of four marks. Sum 0 3.
Pseudocode is very similar to everyday english. Directorate of technical education education department government of gujarat. The algorithm and flowchart include following three types of control structures. Repeat step 5 6 and 7 as long as the largest and smallest number are there 5.
Add first testscore to sum 5. Get the third testscore 8. Add to sum 9. Algorithm and flowchart are programming tools.
In the sequence structure statements are placed one after the other and the execution takes place starting from up to down. Assign the first number as largest number 3. Get the first testscore 4. Get the forth testscore 10.
Read number and check for largest and smallest with comparision 6. Example 1 write an algorithm to determine a student s final grade and indicate whether it is passing or failing. For the love of physics walter lewin may 16 2011 duration. The flowchart is a diagram which visually presents the flow of data through processing systems.
Read list of all numbers 2. Input a set of 4 marks. 1 a algorithm 1. This means by seeing a flow chart one can know the operations performed and the sequence of these operations in a system.
Get the second testscore 6. Problem solving phase produce an ordered sequence of steps that describe solution of problem this sequence of steps is called an algorithm implementation phase implement the program in some programming language eemq 1224 2. Assign the first number as smallest number 4. Add to sum 11.
