Question

Convert this java code to C++. Also i have given the file format below for reference. The file has a name and marks separated by a white space. Want to get the name and parse numbers (marks) into a vector given as: vector<int> marks

Paul 24 56 73 80 90

public StudentEntry(String line) {

int nameEnd = line.indexOf(‘ ‘);

name = line.substring(0, nameEnd);

line=line.substring(nameEnd +1);

String[ ] splitLine =line.split(“\\s”);

for (int i=0; i<size; i++) {

marks[i] = Integer.parseInt(splitLine[i]);

}

}

Answer 1

#include <string.h>
#include <iostream>
#include <vector>

using namespace std;
  
int main()
{
char str[] = "Paul 24 56 73 80 90 ";
vector<int> marks;

// Returns first token
char *token = strtok(str, " ");
string name=token;
cout<<"Name : "<<name;
token = strtok(NULL, " ");
// Keep printing tokens while one of the
// delimiters present in str[].
while (token != NULL)
{
int n = stoi(token);
marks.push_back(n);
token = strtok(NULL, " ");
}
cout<<"Marks : \n";
for(int i=0;i<marks.size();i++)
cout<<marks[i]<<" ";
return 0;
}
