c - Loop through user input with getchar -


i have written small script detect full value user input getchar() function in c. getchar() returns first character tried loop through it... code have tried myself is:

#include <stdio.h>  int main() {     char = getchar();     int b = strlen(a);      for(i=0; i<b; i++) {         printf("%c", a[i]);     }     return 0; }

but code not give me full value of user input.

you can looping part way

int c; while((c = getchar()) != '\n' && c != eof) {     printf("%c", c); }

Using Java 8 lambdas/transformations to combine and flatten two Maps -

i have 2 maps: map<a, collection<b>> mapab map<b, collection<c>> mapbc i transform them map<a, collection<c>> mapac , i'm wondering if there's smooth way lambdas , transformations. in particular case, collections sets, i'd solve problem collections in general. one thought had first combine 2 maps map<a, map<b, collection<c>>> , flatten it, i'm open approach. data notes: b should occur in value collection associated 1 a , , same true mapbc (a given c mapped 1 b ). result, there should 1 path given a given c , although there may a -> b mappings there no b -> c mappings , there may b -> c mappings there no corresponding a -> b mappings. these orphans don't appear in resulting mapac . for sake of comparison, here's example of purely imperative approach same problem: map<a, collection<c>> mapac = new hashmap<>(); (entry<a, collection<b>> entry...
