value1 1 word
value2 2 word
value3 3 word
-----------------------------
How would I get it to read just the first two words of the 3 lines with "value" in them?
Like to store in an array where a specific value is related to the number beside it.
So how could I also change the number from a string to an int so I could print out a list like:
value1 = 1
value2 = 2
etc...
I want to use the integers for something, but I want the "value1" words to remain strings.
How would I go about something like that?
It always reads the entire line with getline(), and every single word as it loops when I use file >> temp. I just want to have the first two saved and the number to be an int for use later.
fstream file("filename.txt");
int i;
string str;
while(true){
file >> str >> i;//read value1 to a string and 1 to an int.
file.ignore(numeric_limits<streamsize>::max(), '\n');//ignore the rest of the line.
if(!file) break;//if there was an error (end of file, for example) quit reading.
//do something with str and i.
//I guess what you need is to put them in a map.
}
file.close();
