Hi,all I'm writing a simple c program on my m1 MacBook with vscode ,but when I complied the project, error occurs: Undefined symbols for architecture arm64: "_main", referenced from: implicit entry/start for main executable ld: symbol(s) not found for architecture arm64 clang: error: linker command failed with exit code 1 (use -v to see invocation) I installed Xcode and used vscose and my program is : #include <cstdio> int main() { char name[100];printf("please input your name:"); scanf("%s",name); printf("hello,%s",name); }
