Question

CSC331: Data Structures

NOTE: Please read the instructions carefully. If you do not understand please do not attempt to answer the question. This is Data Structure. The question is not asking to write a C++, the C++ code is already provided. The question is asking to use COMMAND PROMPT find the cpp file where the code is written, display the message “Hello World!” through COMMAND PROMPT. Then using COMMAND PROMPT to also output the message “Hello World!” into a text file.

-After implementing(writing) the C++ code below that displays the message “Hello World!” on the console.

#include <iostream>

int main()

{

printf("Hello World! Assignment 1 cpp\n");

}

Using COMMAND PROMPT:

-The program should be run from the COMMAND LINE using redirection to capture the output in an output text file called “Data.txt”.

- A screen shot image showing the program execution should be provided

THANK YOU. PLEASE PROVIDE ANY COMMENTS IF POSSIBLE

Answer 1

1. first install a compiler: Download from here

2. Then type the C/C++ program, save it.

3. Then open the command line and change directory, using cd to the particular directory where the source file is stored.

   like: cd C:\Documents and Settings\...

4. Then to compile/run type in the command prompt,

   gcc sourcefile_name.c or gcc -o outputfile.exe

to save output in a file use fopen and fclose

 freopen ("myfile.txt","w",stdout);
  printf ("This sentence is redirected to a file.");
  fclose (stdout);
