Algorithms and Flowchart in C Programming
Algorithms
- 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?
Ans.
step 1 : start
step 2 : input number
step 3 : rem=number mod 2
step 4 : if rem=0 then
print "number even"
else
print "number odd"
endif
step 5 : stop
Flowchart
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"?
Ans.
 |
| Figure: Flowchart example of C program |
