Question

C++ Only. Don't use other libraries other than #include <iostream> and using namespace std;

Write a function maxTemp which takes a filename as string argument and returns the maximum temperature as float type for the week. Input file will contain temperature readings for each day of the week. Your function should read each line from the given filename, parse and process the data, and return the required information. Your function should return the highest temperature for the whole week. Empty lines do not count as entries, and should be ignored. If the input file cannot be opened, return -1. Remember temperature readings can be decimal and negative numbers.

• Each line of the file contains two elements, separated by commas (,)
  • DAY,TEMPERATURE

    Monday,52
    

Note: The split() function is provided, and functions as it does in the homework assignments, to make parsing the output easier. Recall that split takes a string s and splits it at the input delimiter sep, to fill the array words[] up to a capacity of max_words. The return value of split is the number of actual words the string is split into.
int split(string s, char sep, string words[], int max_words)

Example

File Contents
Monday,52 Tuesday,55 Wednesday,50 Thursday,45 Friday,39 Saturday,20 Sunday,35
Return Value    55

Answer 1

float maxTemp(string fileName) {
        ifstream infile("thefile.txt");
        
        float maxTemp = -1;
        
    if (infile) {
                
                string line;
                while (getline(infile, line)) {
                        
                        if(!line.empty()) {
                                string parts[2];
                                
                                // call your split function
                                split(line, ',', parts, 2);     

                                float temp = stof(parts[1]);
                                if(temp > maxTemp) {
                                        maxTemp = temp;
                                }
                        }                       
                }                               
    } else {
                // can not be parsed.
        return -1;
    }
}

You have not shared the split function, so i can not run the code and provide a output screenshot. plz let me know if any issues.
