i'm having troubles sscanf() function read doubles. have comma separated text file this: abc,def,0.465798,0.754314 ghi,jkl,0.784613,0.135264 mno,opq,0.489614,0.745812 etc. so first line fgets() , use sscanf() 2 string , 2 double variables. fgets(buffer, 28, file); sscanf(buffer, "%4[^,],%4[^,],%lf[^,],%lf[^\n]", string1, string2, &double1, &double2); printf("%s %s %f %f\n", string1, string2, double1, double2); but output is: abc def 0.465798 0.000000 ghi jkl 0.784613 0.000000 mno opq 0.489614 0.000000 so somehow doesn't scan last float. i've tried %lf[^ \t\n\r\v\f,] , %lf still doesn't work. change "%4[^,],%4[^,],%lf[^,],%lf[^\n]" to int result; result = sscanf(buffer, "%4[^,],%4[^,],%lf,%lf", string1, string2, &double1, &double2); if (result != 4) // handle error notice & on double1 , double2 - likley typo. also strongly recommend check result 4. not checking sscanf(

i working on rest api based on node.js , chose postgresql database store data. suppose database has 2 tables names user , comment . comment belongs 1 user , when decide remove user , comment 's of him/her must removed. so, designed table follows: create table user( user_id serial, username varchar(32) not null, password varchar(32) not null, constraint pk_user primary key (user_id), constraint uq_user unique (username) ) create table comment( comment_id serial, user_id integer not null, content text not null, constraint pk_cmnt primary key (comment_id), constraint fk_cmnt foreign key (user_id) references user(user_id) on update cascade on delete cascade ) but don't run code , use node-orm2 instead. designed 2 simple models handle simple code: var user = db.define('user', { username: { type: 'text', size: 32, // varchar(32) required: true, // not null unique: true
