how to save system function output into a variable in c++
#include <iostream>
#include <cstdio>
#include <cstdlib>
#include <array>
int main() {
std::array<char, 128> buffer;
FILE* pipe = popen("system_command_here", "r");
if (!pipe) {
return EXIT_FAILURE;
}
std::string result;
while (fgets(buffer.data(), buffer.size(), pipe) != nullptr) {
result += buffer.data();
}
pclose(pipe);
// Now 'result' contains the output of the system command
return EXIT_SUCCESS;
}
