How to extract a number into digits using R? -
suppose have number: 4321
and want extract digits: 4, 3, 2, 1
how do this?
alternatively, strsplit:
x <- as.character(4321) as.numeric(unlist(strsplit(x, ""))) [1] 4 3 2 1 c++ - Linked List error when inserting for the last time -
so have part of code here this loop 5 times (max = 5) insert word link list. for ( int = 0 ; < max ; i++ ) { string alphabet = g->returnalphabets(); l[i]->addwords(alphabet[i]); } and have insert word part here string line; fstream myfile ("words.txt"); while (!myfile.eof()) { getline(myfile,line); if ( alphabet == line[0] ) { listnode *newnode = new listnode; if ( head == null ) { newnode->item = alphabet; newnode->next = null; head = newnode; } else { newnode->item = line; prev = cur; prev->next = newnode; } cur = newnode; } } myfile.close(); my problem gives me error on last loop. meaning on max = 4, insert node. rest of loop fine. when decrease max 4 meaning loop 4 times, program error-free when program loops 5 times gives error. anyone can poin...
