c and c++ tutorials // online learning spot
scanf(<field 1>,<field 2>) has 2 fields or 2 sections or we can say 2 parameters. These parameters are seperated by each other using a comma. It is compulsory to give 1st parameter and second parameter is optional ( we saw in previous example scanf("%c") ).
Now question arises what is this parameter?
To understand the word "parameter" let us have an example :
To calculate volume of a cube we needed its length breadth and height. These are called parameters of cube, that are needed to calculate its volume.
Similarly scanf() needed 1 compulsory parameter and 1 is optional.
What are types of scanf's parameters?
1st parameter is a string that contains type specifier of input and 2nd is a list of variables, these variables will store those input values.
What are Type Specifier?
They are used to identify the type of incoming data stream.
Some basic type specifier

- character input : %c
- integer input : %d
- real number input : %f
we will later understand them more, now take a look on variables in next lesson.
