 hàm nhập thiếu dấu & ở scanf scanf("%d",a[i]); cảm ơn bạn,mình sữa rồi nhưng mà vẫn bị lỗi trên à -

Each unresolved external symbol first gets reported by a LNK2001 or LNK2019 error. The LNK1120 message comes last, and shows the unresolved symbol error count. You don't need to fix this error. What does lnk1120 mean?Each unresolved external symbol first gets reported by a LNK2001 or LNK2019 error. The LNK1120 message comes last, and shows the unresolved symbol error count. You don't need to fix this error. This error goes away when you correct all of the LNK2001 and LNK2019 linker errors before it in the build output. Why am I getting lnk2001 errors?You should also be getting LNK2001 errors listed what is unresolved. What are those? When you created the project, you made the wrong choice of application type. When asked whether your project was a console application or a windows application or a DLL or a static library, you made the wrong chose windows application (wrong choice). What does unresolved external errors mean?Actually the unresolved external errors basically means that the compiler has no idea what getArea is because the function prototype is wrong (In the return type and the parameters), it doesn't really have anything to do with the function call though the call to the function is wrong also like you said. |
