Question

I have a set of strings which looks like
“4 7 14 0 2 blablabla”
“3 8 1 40 blablablablabla”
…

The first number N correspond to how many numbers will follow.
Basically, the format of a string is N+1 numbers, separated with a space, followed by an unknown number of irrelevant characters at the end that I don’t need.

How can I get all the numbers in variables or a dynamic structure given that I don’t know the number N in advance ?

In other words, I’d like something like:

sscanf(s, "%d %d %d %d",&n,&x,&y,&z);

which would work no matter how many numbers in the string.

Answer 1

int input;
std::vector<int> ints;
while(std::cin >>  input)  //read as long as there is integer
       ints.push_back(input);
std::cin.clear(); //clear the error flag
//read the remaining input which most certainly is non-integer
