The program closing after one line usually means one of three things: it finishes normally (Explorer closes the console window), it hits EOF/loop logic and exits after one input, or it crashes. 's joke about returning immediately is a reminder that an early exit will "solve" the closing symptom but not the root cause; 's hint to block for input at the end is useful for the double-click case. Immediate steps to triage and fix before your deadline:

  • Run the exe from a command prompt instead of double-clicking. This keeps the console open and shows error messages. Also capture output for inspection: 

    yourprog.exe > output.txt 2>&1

  • If the program accepts multiple lines, check the loop that reads input (use a loop that checks EOF/return status). If it only reads one line, the loop condition or an early break is likely the bug.

  • Make sure the binary is a console app. In Visual Studio the linker subsystem controls this; see the MSVC docs on the subsystem option for details (change to Console if needed) (MSVC linker: /SUBSYSTEM).

To give recipients a simple, cross-platform-friendly way to keep the window open when testing, add a final input wait that flushes any leftover input and then waits for Enter:

#include <iostream>
#include <limits>

int main() {
    // ... program logic ...

    std::cout << "Press Enter to exit...";
    std::cin.ignore(std::numeric_limits<std::streamsize>::max(), '\n');
    std::cin.get();
}

For harder-to-find crashes, run under a debugger or add logging to a file. For delivery, include a short README saying “run from cmd” or ship a small .bat wrapper that runs the exe and pauses.

At the very beginning of the main function, insert the line return 0; . Then it will work for zero lines. Problem changed!

HTH HAND

You can't expect serious help on a problem if you don't even explain what the problem is. Unless you need vague, obvious advice, like, "debug the program."

Those two statements contradict each other. Apparently the first statement is false.

Post your program so we can see and test it. Do you mean you don't have a chance to see the program's output because the program closes too fast? If that's the case then put a getchar() just before the return statement in main().
