- A sequential solution of any program that written in human language,called algorithm.
- Algorithm is first step of the solution process, after the analysis of problem, programmer write the algorithm of that problem.
- Example of Algorithms:
Q. Write a algorithem to find out number is odd or even?
step 1 : start
step 2 : input number
step 3 : rem=number mod 2
step 4 : if rem=0 then
print "number even"
print "number odd"
step 5 : stop
1. Graphical representation of any program is called flowchart.
2. There are some standard graphics that are used in flowchart as following:
|Figure: Start/Stop terminal box|
|Figure: Input/Output box|
|Figure: Process/Instruction box|
|Figure: Lines or Arrows|
|Figure: Decision box|
|Figure: Connector box|
|Figure: Comment box|
|Figure: Preparation box|
|Figure: Separate box|
Q. Make a flowchart to input temperature, if temperature is less than 32 then print "below freezing" otherwise print "above freezing"?
