When we assign float f=5.00 We get a compiler error as default type of floating point number is double and cast is neccessary .
Y a cast is not needed when we say float f = 35/6 ;
Some help needed on this..
Thanks in advance.

In the above stmt only integer division will be carried out not float division.bcoz both 35 & 6 will be taken as integers & result will be 35 /6 = 5(digits after decimal point will be truncated).so no cast is needed here.

I hope that answer by priya helps you..! To add more..!
The resultant of the division is integer that is 5 which can be assigned to float. If the question was like 35.0/6.0 then u needed a explicit cast as the the default type of answer is 5.0 double in this case.

floats, if not explicityly casted, need to be declared with the keyword 'f', correct?
float num = 5.0f (this is legal)
Are floats used very often? I can see from a memory conservation point of view why they would be used, but I don't see them too often in practice.
