To initialize a struct that contains bit fields, simply use the ={0}partial initialization list:
int main(){ struct MP3_HEADER { unsigned Sync:11; unsigned Version:2; unsigned Layer:2; unsigned Protection:1; unsigned Bitrate:4; unsigned Frequency:2; unsigned Padding:1; unsigned Private:1; unsigned ChannelMode:2; unsigned ModeExtension:2; unsigned Copyright:1; unsigned Original:1; unsigned Emphasis:2; }; // create an instance and initialize it MP3_HEADER header = {0}; /*set all members to zero*/}When you use a {0} partial initialization list, both C and C++ guarantee that all the members in the struct
