Thread: Reading strings from a file and storing into an array

One easy way is to use strings and a vector....read a line into a string and push it onto the vector.....maybe not the most efficient way...but simple

Code:

#include <iostream>
#include <fstream>
#include <string>
#include <vector>


int main (int nArg,char* szArg[]){

	if(nArg < 2){
		std::cout << "Only pass the name of the file!" << std::endl;
		return 1;
	}
		
	std::ifstream in(szArg[1]);
	if(!in.is_open()){
		std::cout << "Couldnt open the file!" << std::endl;
		return 1;	
	}
	
	std::vector<std::string> vec;
	std::string str;
	
	while(!in.eof()){
		getline(in,str);
		vec.push_back(str);
	}
	
	for(int i = 0;i < vec.size();i++)
		std::cout << vec[i] << std::endl;
	
}
