    The operator>> stops at the first whitespace... use getline. There are plenty of threads about how to use getline, including one only a few notches below this one with the same question.

    i tried this

    Code:
    ifstream a_file("test.txt");
    a_file.getline(text, 50);
    a_file.close();
    it compiles but does not print anything when running.

    try this
    Code:
    #include <iostream>
    #include <fstream>
    using namespace std;
    int main()
    {
    	char text[64];
    	ifstream a_file("test.txt");
    	a_file.getline(text,64);
    	cout << text << endl;
    
    	return 0;
    }
