A Simple, Easy, and Efficient Way to Initialize Structs

A Simple, Easy, and Efficient Way to Initialize Structs

Struct instances created on the stack are uninitialized (i.e., contain garbage values). The easiest, most efficient, and future-proof way to initialize them is:

 struct  PlainData {char [20] name;long ID;char [15] phone;//... other fields as many as you like };int main(){	PlainData data = {0};  //automatic initialization of the rest 					//of data to binary zeroes is 						//guaranteed both for C and C++}

This is a much better way than manually assigning values to all the fields of the struct (which may also turn into a maintenance nightmare when new struct members are added or deleted) and it is at least as efficient as a memset() call?usually much more efficient.
