Question

One common use of this class is to parse comma-separated integers from a string (e.g., "23,4,56").

stringstream ss("23,4,56");
char ch;
int a, b, c;
ss >> a >> ch >> b >> ch >> c;  // a = 23, b = 4, c = 56

You have to complete the function vector parseInts(string str). str will be a string consisting of comma-separated integers, and you have to return a vector of int representing the integers.

Note If you want to know how to push elements in a vector, solve the first problem in the STL chapter.

Input Format

The first and only line consists of n integers separated by commas.

Output Format

Print the integers after parsing it.

P.S.: I/O will be automatically handled. You need to complete the function only.

Sample Input

23,4,56

Sample Output

23
4
56

How do I input a string to then convert the string into a integer vector.

Answer 1

vector<int> parseInts(string str){
stringstream ss1(str);//convert string to stringstream
vector<int> ints;//vector to hold int
int num;//variable to read integer from stringstream
char ch;//variable to read the comma
while(ss1>>num){//keep reading from the string untill an integer is read
   ints.push_back(num);//insert it into the vector
   ss1>>ch;//read the comma
   }
return ints;//return the vector
}
