  • Have you tried using the native C++ file IO? Try using that and revising your answer; perhaps using a for loop to loop through all the lines of the document and append it to a string? Please do this soon so that people don't put this question on hold. – Atutouato Feb 02 '14 at 02:47

Well the easy solution is: 

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

std::string execu(char* cmd) {
    FILE* pipe = popen(cmd, "r");
    if (!pipe) return "ERROR";
    char buffer[128];
    std::string result = "";
    while(!feof(pipe)) {
        if(fgets(buffer, 128, pipe) != NULL)
            result += buffer;
    }
    pclose(pipe);
    return result;
}
std::string result = execu("curl http://www.facebook.com");

But this is not considered safe unless you know the string passed is not going to blow anything up.
