For ex: struct Client { string name; int sm_index; int client_id; int user_id; } Sorted on based of sm_index. How can i find and fetch the data of that struture whose sm_index matches our target structure. WebYou need to actually create an instance of the structure. A normal struct declaration follows the form struct struct-name { members } inst; So you need to declare it as struct FR { size_t n; struct FR_1 { unsigned char r; unsigned char g; unsigned char b; } fr1; }; Now you can write FR fr; fr.fr1.r = 255; . . .
