Hey, In the video why it showed the error when 1.2 was passed as a key without being stored in a key variable of data type float. Please explain this?
Generic Programming Doubt
compiler is treating 1.2 as double instead of float .
hence due to type mismatch it is showing compile error
But we can use the float data type in C++, so why compiler dosen’t differentiate between float and double or is it treated as same? If so, then what is the difference between the float and double in general.
by default compiler treats decimal numbers as double.
if u want to make them float then u have to declare it explicitly
