Answer / abhilash s thachil

There is a catch in the question. We can have function overloading with same number of arguments with different return types. One step ahead, we can have function overloading with same number of arguments provided the type and order of the arguments are not same irrespective of return type.

no . we can have same function name with arguments differ
in number,type and different order of data types . but for
function overloading compiler ignore return type.

sequence of data type irrrespective of return type ..
