Question

anyone know why I can't find my output on Xcode? it compiles but it wont show me any output.

#include <iostream>
#include <string>
#include <fstream>
using namespace std;

void print(string rawName, string formattedName);

enum Married {
SINGLE, MARRIED, DIVORCED
};

Married isMarried(string s) {

Married married;

if (s == "M") {
married = MARRIED;
}
else if (s == "S") {
married = SINGLE;
}
else if (s == "D") {
married = DIVORCED;
}

return married;
}

string formatName(string gen, Married mar, string lN, string fN, string mI) {

string formattedString;

if (gen == "M") {
formattedString += "Mr. ";
}
else if (gen == "F" && (mar == 0|| mar == 2)) {
formattedString += "Ms. ";
}
else
formattedString += "Mrs. ";

formattedString += fN + " ";

if (mI != " ") {
formattedString += mI + " ";
}

formattedString += lN;

return formattedString;
}

void process() {

ifstream infile;
infile.open("mp6names.txt");

string gender;
//string maritalStatus;
string lastName;
string firstName;
string middleInit;
Married maritalStatus;
string strFull;

while (getline(infile, strFull)) {
gender = strFull.substr(0, 1);
maritalStatus = isMarried(strFull.substr(1, 1));
string str = strFull.substr(2);
string::size_type pos1 = str.find_first_not_of(" ");
string::size_type pos2 = str.find(",");

//Retrieve last name from line by using pos1 & pos2 variables
lastName = str.substr(pos1, (pos2 - pos1));

//to trim off last name from original string and then locate the first non-empty space in newString
string newStr = str.substr(pos2 + 1);
pos1 = newStr.find_first_not_of(" ");

//Locate first name
firstName = newStr.substr(pos1, newStr.substr(pos1).find(" "));

//Routine to find last instance of white space,
string findMidInit = str.substr((str.find_last_of(" ")) + 1);
if (findMidInit != " ") {
middleInit = findMidInit;
}

string formattedName = formatName(gender, maritalStatus, lastName, firstName, middleInit);

print(str, formattedName);
}
}

void print(string rawName, string formattedName) {

cout << "--------------------------------------------------------" << endl;
cout << "Unformatted name: " << rawName << endl;
cout << "Formatted name: " << formattedName << endl;
}

int main()
{
process();

return 0;
}

It may be because you do not have "mp6names.txt" file. In process function, program is taking input from "mp6names.txt" file. so, you need to have "mp6names.txt" file in your code directory.

e.g.

So, you can see that i have "mp6names.txt" file in code directory. my code file name is p.cpp.

And

Also, Make sure that your "mp6names.txt" file has right structure. so that your program is able to fetch data correctly.

I have created sample file as below:

First character is gender. i.e. Male(M) or Female(F)

Second character is Martial Status. i.e. M-> Married or S-> Single etc.

Then Name...

So the output with above "mp6names.txt" file using your code is below:
