i am to write a function called splitLine() in c++. can someone please help? im really confused
splitLine () {
string temp = aLine;
string *tempLine = strtok(temp, " ");
free(temp)
countNum = sizeOf(tempLine);
}
You're misunderstanding the instructions.
The strtok
function operates on nul terminated char arrays (aka C strings) not C++ strings. So create a temporary 'string' actually means this
// create temporary string which is a copy of aLine
char* temp = new char[aLine.size() + 1];
strcpy(temp, aLine.c_str());
// extract words from temp
...
// free temporary string
delete[] temp;
Breaking the temporary string into words with strtok
means writing a loop . strtok
will extract one word at a time. I'm sure you can find examples of this on the internet. So I'll leave that to you.
