Question

I would like to store lines in a file such as

15 1 0 0 0 0
33 1 0 0 0 0
29 1 0 0 0 0
18 1 0 0 0 0
25 1 0 0 0 0

to become elements of an array. So if I do

#include <stdio.h>
#include <vector>
using namespace std

char* file = "somefile.txt"
FILE *fb_r = fopen(file,"r");
char line[100];
vector <char> lineArr;
string lineElement;
while(fgets(line,256,fb_r){
  sscanf(line, "%s", &lineElement);
  lineArr.push_back(lineElement);  //problem arises here
}

but I get the error :
Can’t call vector >::pushBack(lineElement)

Answer 1

Well your vector contains single chars

vector <char> lineArr;

and it looks like you are trying to push an std::string?
