I have a text file like this :
Sting Another string 0 12 0 5 3 8
Sting Another string 8 13 2 0 6 11
And I want to count how many numbers are there. I think my best bet is to use while type cycle with a condition to end counting then another line starts but I do not know how to stop reading at the end of a line.
Thanks for your help in advance ;)
Split your input
stream into lines
std::string line;
while (std::getline(input, line))
{
// process each line here
}
To split a line into words, use a stringstream:
std::istringstream linestream(line); // #include <sstream>
std::string word;
while (linestream >> word)
{
// process word
}
You can repeat this for each word to decide whether it contains a number. Since you didn't specify whether your numbers are integer or non-integers, I assume int
:
std::istringstream wordstream(word);
int number;
if (wordstream >> number)
{
// process the number (count, store or whatever)
}
Disclaimer: This approach is not perfect. It will detect "numbers" at the beginning of words like 123abc
, it will also allow an input format like string 123 string
. Also this approach is not very efficient.
