Re: [algogeeks] c doubt again
An asterisk indicates that the data is to be retrieved from the use
but ignored, i.e. it is not stored in the corresponding
argument...hence the third value entered gets stored for b and for c
the output comes to garbage value
One beautiful application of such type of implementation is in finding
the sum of 2 variables without using + operator..:)

Re: [algogeeks] c doubt again
sorry by mistake i added it in scanf situation..
actually this type of specifier can be used with printf statement for
finding the sum...
look at the code below
main()
{
int a=9;
int b=3;
printf(%d\n,printf(%*s%*s,a,,b,));
system(pause);
}

Re: [algogeeks] c doubt again
there is no as such logic behind it..its just the format specifier...
u must be knowing printf returns the number of values it has printed(u can
check that)
now, in printf if u write like *printf(%7s,a), *it will create 7
columns for the output and print a in the last column and the returned value
of this printf will be 7..(u can check it)
now if u write *printf(%*s,7,a)* then u r giving additional information
of format specifier i.e 7..returned value of this printf is also 7.
Hence the above logic..hope I am able to clarify it...:)

there is no as such logic behind it..its just the format specifier...
u must be knowing printf returns the number of values it has printed(u
can
check that)
now, in printf if u write like *printf(%7s,a), *it will create 7
columns for the output and print a in the last column and the returned
value
of this printf will be 7..(u can check it)
now if u write *printf(%*s,7,a)* then u r giving additional

also
7.
Hence the above logic..hope I am able to clarify it...:)

actually this type of specifier can be used with printf statement for
