The problem with your code is that the wildcard *is being expanded by the shell before being passed to find. Quote it thusly:
您的代码的问题在于通配符*在传递给 find 之前被 shell 扩展。引用它：
for i in `find /home/Phil/Programs/Compile -name '*.cpp'` ; do echo $i ; done
xargsas suggested by others is a good solution for this problem, though.
xargs不过，正如其他人所建议的那样，这是一个很好的解决方案。

findhas an option for doing exactly that:
find有一个选项可以做到这一点：
find /p/a/t/h -name '*.cpp' -exec g++ {} \;

You could use xargs like:
你可以使用 xargs 像：
find folder/ -name "*.cpp" | xargs g++
find folder/ -name "*.cpp" | xargs g++
Or if you want to handle files which contain whitespaces:
或者，如果您想处理包含空格的文件：
find folder/ -name "*.cpp" -print0 | xargs -0 g++
find folder/ -name "*.cpp" -print0 | xargs -0 g++

How about using xargs like this:
像这样使用 xargs 怎么样：
find $working_dir -type f -name *.cpp | xargs -n 1 g++
