1.[Error] G:\程序語言cpp\Debug\圓.cpp:4: error: `main' must return `int'
我學的C++的main()函數都是返回int值得，int main()，你改成這樣最后return 0就可以了
2.[Error] G:\程序語言cpp\Debug\圓.cpp:6: error: stray '\163' in program
[Error] G:\程序語言cpp\Debug\圓.cpp:6: error: stray '\187' in program
這個是出現中文字符了，for(x=25,y=25；x<=475,y<=475;x+=20,y+=20)中的分號是中文符號，改成英文的就可以了
3.[Error] G:\程序語言cpp\Debug\圓.cpp:25: error: expected `}' at end of input你程序的最后少了個"}"
