[C++] Changing Case

[aitf311]

bool getName(ifstream& inFile, ofstream& outFile)

{

customer Temp;

if (inFile >> Temp.id >> Temp.firstName >> Temp.lastName)

{

outFile << tolower(string Temp.lastName) << ','

<< Temp.firstName << endl;

cout << "ID# " << Temp.id;

return true;

}

else

{

return false;

}

}

This is C++. Temp.lastName and Temp.firstName are in Caps. How do I make it so it formats it so the first letter of the first and last name are caps and the rest arent?

Please remember to mention the name of the programming language in your topic title. It helps people to help you more easily.

So topics should be "[Language] Subject", e.g "[VB] Reading text files".

Thank you.

just remember that strings in c++ are just arrays of characters with a null terminator as the last character

in the array. What you need to do is just access the first character and change it, something like this should work:

After you have lowered the string, do this

Temp.lastName[0]=toupper(Temp.lastName[0]);
Temp.firstName[0]=toupper(Temp.lastName[0]);

And that should work. Hope that helps

Causes 2 errors for me:

C:\Program Files\Microsoft Visual Studio\MyProjects\Proj8\main.cpp(106) : error C2679: binary '=' : no operator defined which takes a right-hand operand of type 'int' (or there is no acceptable conversion)

C:\Program Files\Microsoft Visual Studio\MyProjects\Proj8\main.cpp(106) : error C2143: syntax error : missing ';' before '<<'

This is supposed to make an all caps name turn into first capped rest lowercased like MARK--->Mark

Causes 2 errors for me:

Both errors are on line 106 (according to the compiler). Therefore, please post lines 105 - 107.

This is supposed to make an all caps name turn into first capped rest lowercased like MARK--->Mark

In that case, you need to make all the letters except the first lowercase.

Sorta like this:

for (int i = 1; i < Temp.lastName.length(); i ++)
    Temp.lastName[i] = tolower(Temp.lastName[i]);

{

customer Temp;

if (inFile >> Temp.id >> Temp.firstName >> Temp.lastName)

{

outFile <<

for (int i = 1; i < Temp.lastName.length(); i ++)

Temp.lastName = tolower(Temp.lastName); << ','

<< Temp.firstName << endl;

cout << "ID# " << Temp.id;

return true;

}

else

}
