Hello Programmers, In this post, you will know how to solve the StringStream in C++ HackerRank Solution. This problem is a part of the HackerRank C++ Programming Series.
One more thing to add, don’t directly look for the solutions, first try to solve the problems of Hackerrank by yourself. If you find any difficulty after trying several times, then you can look for solutions.
StringStream in C++ HackerRank Solution
Problem
stringstream is a stream class to operate on strings. It basically implements input/output operations on memory (string) based streams. stringstream can be helpful in different type of parsing. The following operators/functions are commonly used here
- Operator >> Extracts formatted data.
- Operator << Inserts formatted data.
- Method str() Gets the contents of underlying string device object.
- Method str(string) Sets the contents of underlying string device object.
Its header file is sstream.
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
StringStream in C++ HackerRank Solution
#include <sstream>
#include <vector>
#include <iostream>
using namespace std;
vector<int> parseInts(string str)
{
// Complete this function
stringstream ss(str);
vector<int> result;
char ch;
int tmp;
while (ss >> tmp)
{
result.push_back(tmp);
ss >> ch;
}
return result;
}
int main()
{
string str;
cin >> str;
vector<int> integers = parseInts(str);
for(int i = 0; i < integers.size(); i++)
{
cout << integers[i] << "\n";
}
return 0;
