Question

I have a C struct with about 17 members struct settings currentProfile and would like to initialise it all members to zero. (I have tried this both with the uber-correct struct syntax and with typedef syntax)

To set all members to zero I use currentProfile = {0}

at this line the compiler gives the erro Expected an expression

Am I initialising correctly?
Thanks

You are doing an (invalid) assignment not an initialization.

To initialize your struct object with all members set to 0:

struct settings currentProfile = {0}; 

To set all the members of the struct object to 0 after its declaration:

memset(&currentProfile, 0, sizeof currentProfile);
