Algorithms and flowcharts are two different ways of presenting the process of solving a problem. Algorithms consist of steps for solving a particular problem, while in flowcharts, those steps are usually displayed in shapes and process boxes with arrows. So flowcharts can be used for presenting algorithms. EdrawMax will introduce some examples of algorithm flowcharts.
1. Rules of Drawing Flowcharts for Algorithms
Flowcharts usually consist of basic symbols and shapes that have a specific representation. The symbols make the chart more meaningful and easy to understand.
Some of the most standard symbols include shapes like a rectangle representing an operation, a parallelogram showing input and output of data, a cylinder indicating the start/end, while a diamond represents a decision. Read more about flowchart symbols.
However, knowing these symbols well and using them in a flowchart involves critical thinking. Here are some basic rules that need to be considered while drawing a flowchart.
- All the boxes and shapes in a flowchart should be connected with arrows to indicate a logical order and make it easy to follow.
- Make sure the flow direction is consistent and not ambiguous. The flow charts always flow from either left to right or top to bottom.
- Every chart will begin with a Start box and end with a Terminal box, with the latter only having one flow line associated with it.
- All the shapes, symbols, and lines should be consistent. You can also add a symbol key to make it easier to follow the chart.

- Step 4: Print the Integer C.
Example 2: Determining the Largest Number Among All the Entered Integers
- Step 1: Read the Integer A.
- Step 2: Read Integer B.
- Step 3: If B is greater than A, then print B, else A.
Example 3: Work Out All the Roots of a Quadratic Equation ax² +bx+c=0
- Step 1: Enter the variables a, b, c, D, x1, x2, rp, and ip.
- Step 2: Evaluate the discriminant by using the formula: D= b²- 4ac
- Step 3: Print rp and ip.
Example 4: Find the Fibonacci series till term ≤ 1000
- Step 1: Declare the variables i, a, b, show.
- Step 2: Enter the values for the variables, a=0, b=1, show=0
- Step 3: Enter the terms of the Fibonacci series to be printed, i.e=, 1000.
- Step 4: Print the first two terms of the series.
- Step 5: Loop the following steps:
- Show = a + b
- a= b
- b = show
- Add 1 to the value of i each time.
- Print Show
Example 5: Calculate the Sum of The First 50 Numbers
- Step 1: Declare number N= 0 and sum= 0
- Step 2: Determine N by N= N+1
- Step 3: Calculate the sum by the formula: Sum= N + Sum.
- Step 4: Add a loop between steps 2 and 3 until N= 50.
- Step 5: Print Sum.
Example 6: Find the largest price among 100 given values and reduce it by 10%
- Step 1: Read the 100 prices.
- Step 2: Compare the first price with the next and let the greater of the two be 'max' in the 'max index.
- Step 3: Loop it until the largest price has been found.
- Step 4: Reduce the 'max' value by 10% using the formula: prices [max index] = prices [max index] x 0.9.
- Step 5: Print.
Example 7: Arrange the numbers X, Y, Z in descending order
- Step 1: Input the value for variables X, Y, Z.
- Step 2: Read the integers X, Y, Z.
- Step 3: Check if x>y, x>z, y>z
- Step 4: Print the possible order.
Example 8: Determine the Highest Common Factor (HCF) of two integers
- Step 1: Read the variables a and b.
- Step 2: If a = b, go to step 4.
- Step 3: If a > b, then: a = a - b. Return to step 2.
- Step 4: Print a or b.
Example 9: Determine and Output Whether Number N is Even or Odd
- Step 1: Read number N.
- Step 2: Set remainder as N modulo 2.
- Step 3: If the remainder is equal to 0, then number N is even, else number N is odd.
- Step 4: Print output.
Example 10: Calculate the Interest of a Bank Deposit
- Step 1: Read amount.
- Step 2: Read years.
- Step 3: Read rate.
