Question

Hello, I stuck doing c++ program

The program will be recieved from the user as input name of an input file and and output.file.

then read in a list of name, id# and score from input file (inputFile.txt)

and initilized the array of struct.

find the student with the higher score and output the students info in the output file

obtain the sum of all score and output the resurl in output file.

prompt the user for a name to search for, when it find the, will output to a file(output)

prompt for another name until the word done is typed.

calclate and output the sum of all scores for the found name

header file.   

*dont make array size a global concstan. it must pass it as a parameter as necessary

function for

input function ( propagate the array of structs to real in all the data) “one array of a struct “, must declare a struct with three members(names, ids, scores). read all the data frim infile.txt

search function score

sum function

search fuction name (search for a name and return the proper index

console input / output

type input file name : inputFile.txt

type output file name : outputFile.txt

type student’s name you are searching for (type done to exit) : Emma

type student’s name you are searching for (type done to exit): Jason

type student’s name you are searching for (type done to exit): done

Thank you!
