C++ Placement DSA Course
Lecture 1
We will learn about flow charts, pseudocode and programming
languages
...
After this, we will write our program
...
First question, then given
values, then approach and at last we will code it
...
The flow chart constitute various components, connected with
each other Bhaiyan says
...
Terminator is used to show the
start and end start of the program
...
Bhaiya explains how to make a flowchart for the
sum of 2 numbers
...
The flow of a flow chart is the same as the flow of
the components of the flow chart
...

We want to make a flowchart for calculating simple interest This is the
formula for simple interest You must have studied it in your school We
started our program from this start block I do n't know p , r , t , so I
need to take them as inputs first So I asked user to give me the values
for p, r and t So now I have P , R and T So I made this rectangular block
for the calculation part Here I wrote this formula After finding this
answer in the above calculation , I have to print the output too So here I
will print output with this block print SI and then we will end this
program We started the program , took a , b as input then we checked
whether a is less than b or not
...
If any number has 2 as its factor ,
then it is even number or ODD number
...

We have to print something and then increment too You have to Print
and then increase the printed number too You can see here , we printed

and then increased the numbe by 1 But we do n't know how to do it
How we will increase again and again Let 's rub it You know that we
have to start from 1 and print till 5 So if I give you a number which
starts from 1 to 5, will it work ? Your are like , yes , this is what we
needed So I took a number =1 This is not a input , it is a process , so I
wrote it inside rectangular block
...
The catch is , 1 and N are
inclusive here in the answer should be 15
...
We know that we
have to start with num=1 and increment it till N I know N = 5 , Num =1
, and sum =0 in the beginning
...
You will get your homework after this
...

Flowchart shows how to add conditions, loops, input/output,
processing, processing and start/end
...
We learnt about flowcharts in this
lecture, pseudocode and took an overview of programming languages
