从终端运行C ++程序。 在同一终端窗口中获​​取输出

Question

When I run my c++ programs from Terminal (Mac OS X), output from programs is shown in a new Terminal window.

What can I do to prevent the new window, and just have the programs' output straight in the window thats already open?

Answer 1

I believe gcc comes with the XCode tools package.

If you have gcc installed, open terminal window, cd to the directory where you put your cpp file, and type:

g++ myTestFile.cpp -o main; ./main

Replace 'myTestFile' by the name of your file, naturally. you can also rename the 'main' which is just the name of the compiled module, which you need to run by typing ./main to retrieve the output of your code.

Answer 2

I guess you are using the open command.

$ open foo

This will open a new terminal window.

Don't use the open command if you want the program to run in the current terminal window. ^†

$ foo
