averageValuelnFile Language/Type: C++ basics streams file input Related Links: string istream
Write a function named averageValueInFile that accepts a file name as a parameter and reads
that file, assumed to be full of real numbers, and returns the average (mean) of the numbers in
that file. The parameter, filename, gives the name of a file that contains a list of real numbers.
There could be anywhere from zero to many values per line separated by any number of blank
spaces. You may assume that the file exists and follows the proper format. For example, if a file
named input. txt contains the following numbers Then the call of aver ageValueInFile("input.txt") ;
should return 2.75. You may assume that the input file exists and is in the proper format. If the file
does not contain any input values, return .0. Constraints: Your solution should read the file only
once, not make multiple passes over the file data.
