The Task:

Calculate average power consumption and time of each operation performed by

an automatic milling machine.

Phase 0: Optional Output File NamingFunction Output_Name:● Prompt user for output file

nameo a variety of filetypes can be

chosen● Continue to program

void Output_Name (){

cout << "What would you like the output file to be named?" << endl;cout << "Be sure to include the file extension type at the end of the file name." << endl;cout << " Text document, '.txt'. Spreadsheet, '.xls'. Data file, '.dat'." << endl << endl;cout << "Example: 'example.txt' would produce a text file named 'example'." << endl << endl;cin >> output_file;cout << endl;

cout << "The analysis of 'OperationActive' for electric_61-66 is as follows:" << endl;}

Phase 1: Extract Data into Data File

Sequence:

Open and Read file

Search for String

Extract lines containing power

values

Output to Datafile

Phase 1 AlgorithmFunction Data_Grab:● Opens source file● Using a for loop, cycle through

line by lineo assign each line to workspace1o mark specific lines that contain

timestamp information

● Search for the phrase ‘timestamp=’

● Combine into one string● Output string to ‘Timestamp.txt’

void Data_Grab(){

ifstream inData;ofstream outData;

string workspace1;string workspace2;

int ind;

int i;int j;

ind=0; i=0; j=0;

inData.open("OperationActive.xml");outData.open("Timestamp.txt");

for (i==0; i<88; i++){getline(inData,workspace1);if (i==71 || i==74 || i==77 || i==80 || i==83 || i==86 ){ind=workspace1.find("timestamp=");workspace1=workspace1.substr(ind+11,workspace1.length(workspace2=workspace1.substr(0,23);outData << endl << workspace2 << ":";}

if (i==72 || i==75 || i==78 || i==81 || i==84 || i==87){outData << '\n' << workspace1;}}

}

Phase 2: Ready Data

Sequence:

Read Input String

Store in temporary

Phase 2 Algorithm

Main function:● Open file ‘Timestamp.txt’● Initiate while loop to read

through new data in ‘Timestamp’

● Outputs data in pairs, first the time, then the power

● Use str_temp to find average value of str_rawdata

inData.open("Timestamp.txt");outData.open(output_file);

getline(inData,trash);

while (inData.good()){

getline(inData,str_timestamp);getline(inData,str_rawdata);str_temp=str_rawdata;

Phase 3: Display and Write to Output

Sequence:

Read from Integer

Find Elapsed Time

Output Averages and Elapsed Time

to Output File

Phase 3 Algorithm

Main function continued:● Use for loop to calculate

average of each of 25 data lineso Find empty spaceo Add data value into total

‘k’o Shorten data line to next

data input● Divide total by 25 for average

power

for(j==0; j<25; j++){

index=str_temp.find(" ");workspace1=str_temp.substr(0,index);

k = k + stoi(workspace1);str_temp=str_temp.substr(index+1,str_temp.length());}avg=(k/25);

Phase 3 Algorithm

Main function continued:● Output the average

timestamp to screen● Output power average to

screen● Clear loop counters

● Convey thanks and cheer, programs have feelings too.

cout << str_timestamp << " Average Output: " << avg << endl;

cout << str_rawdata << endl << endl;

outData << str_timestamp << " Average Output: " << avg << '\n' << str_rawdata

<< '\n' << '\n';

j=0;k=0;

}cout << "Thank you for making a simple program happy."

<< endl << "Have a wonderful day!" << endl;

cout << “ The End “ << endl;
