strpbrk() problem

Hi!

I problems solving thins assignment:

* I want to read numbers from a file and the numbers may be seperated.like this

200ee4e 66 yyy 888
22 5 6
1

* I want to read just the numbers and sum them up.But i get problems with newline the code stops reading after newlin/space.
It reads 2 0 0 4 but jumps out before 66

Code:

#include <iostream>
#include <fstream>
#include <cstring>
using namespace std;

int main(){

    ifstream inputFile;
    char input[81];
    char test[] = "0123456789";
    char *ptr;
    int teller = 0;
    
    inputFile.open("oppgave2.txt");
    if(!inputFile){
        cout<<"File error\n";


    }
    else{
        inputFile>>input;
        ptr = strpbrk (input, test);
        while(ptr != NULL){


            cout<<*ptr<<" ";
             ptr = strpbrk (ptr+1,test);

           
        }


    }

    inputFile.close();

    return 0;
}

To figure out what happens try

Code:

inputFile>>input;
cout << input << endl;

Then consider using something like getline()

I changed the code a bit. Now i can read the numbers but i get wring sum.
Because the program sums 100 + 34 +4?+67+7?+7+5+5?+63+3?+6+1 =297 while it should be 100+34+67+7+5+63+6+1=283??. I can se that for every space it adds the last number? how to i stop that??

Code:

//Oppgave 2 Øving 1
#include <iostream>
#include <fstream>
#include <cstring>
#include <cstdlib>
using namespace std;
/*
    oppgave2.txt contains
    100er34 67 yyy 7
    5 63 6
    1


*/

int main(){

    ifstream inputFile;
    char input[81];
    char input2[81];
    char input3[81];
    char test[] = "0123456789";
    char *ptr;
    int sum = 0;
    //cout<<"her";
    inputFile.open("oppgave2.txt");
    if(!inputFile){
        cout<<"File error\n";


    }
    else{
        //inputFile>>input;




        while(!inputFile.eof()){

             inputFile.getline(input,81);

             ptr = strpbrk (input, test);

        while(ptr != NULL ){

            cout<<*ptr<<" ";

            sum += atoi(ptr);
            cout<<"sum: "<<sum<<" ";


            ptr = strpbrk(ptr+1,test);


        }
    }
        cout<<"\n sum:"<<sum;

    }

    inputFile.close();

    return 0;
}
