so i'm in middle of working on class called planner [no main in it's separate class], i'm having issue declaring array eclipse. need enter in eclipse see because have no idea means 'syntax error on token ";", , expected'. here code: import java.util.scanner; public class planner { private int maxevents = 1000; private int numevents = 0; private int choice; int[] anarray; anarray = new int [1000]; public void planner() { scanner scan = new scanner (system.in); system.out.print("press 1 add event. 2 display events day. 3 display events week. 4 quit: "); choice = scan.nextint(); if (choice == 1){addevent();} if (choice == 2){displayonedate();} if (choice == 3){displayoneweek();} if (choice == 4){system.out.println("have day.");} else {planner();} } public void addevent() { event newevent = new event(); if (numevents == maxevents){system.out.println("error: no more room.");}...

i'm looking @ past paper course i'm doing @ university, , there question c pointers. i reckon have reasonable grasp of how work, question confusing me: consider running c program fragment: int x[4] = {0,2,4,6}; int *y; y = &x[2]; *(x + 2) = y[1] + 1; value of expression *y afterwards? (a) 2 (b) 4 (c) 5 (d) 7 (e) 8 now, in answers said question, says answer d . i'm super confused, seeing as: the value of x not declared, i'd have thought impossible evaluate x+2 y isn't array, how can y[1] evaluated? why 7 correct answer here? lets break down: int x[4] = {0,2,4,6}; x [0] = 0 x [1] = 2 x [2] = 4 x [3] = 6 int *y; pointer integer y point location in x x [0] = 0 // <-- y ? x [1] = 2 // <-- y ? x [2] = 4 // <-- y ? x [3] = 6 // <-- y ? y = &x[2]; have specified y points x[2] x [0] = 0 x [1] = 2 x [2] = 4 // <-- y (or y[0]) x [3] = 6 *(x + 2) same x[2] so: x[2] = y[1] + 1...

for debugging purposes, output html comment indicating filename of current cshtml file @ beginning , end of every cshtml file. for example, i'd when view source of generated webpage, see this: <!-- begin _layout.cshtml --> ... headings , such ... <!-- begin about.cshtml --> ... generated content about.cshtml ... <!-- end about.cshtml --> ... footers , such ... <!-- end _layout.cshtml --> i'm new platform, i'm not sure right terminology this, let alone in api look. i'm hoping @ least can edit of cshtml files , reference object @ runtime contains filename property, in syntax similar to: <!-- begin @object.optionalproperty.optionalsubproperty.filename --> or, alternatively, way modify rendering engine automatically @ beginning , end of every rendered file. thank time , responses.

i trying run execl pathname built command line arguments. not working hardcoded strings being concatenated still did not work. if supply char *path = "some path name" , pass execl, works correctly. #include <stdio.h> int main(int argc,char *argv[]){ //set char path name char pathname[256]; strcat(pathname,"/bin/"); strcat(pathname,"ls"); //"ls" replaced arg[1] int pid=fork(); if (pid==0){ execl(pathname,"ls",(char *)0); } else{ wait((int*)0); } return 0; } i've printed out pathname make sure "/bin/ls" is. the problem here: char pathname[256]; strcat(pathname,"/bin/"); you did not initialize pathname . therefore, contents "indeterminate" , call strcat has officially known undefined behavior -- allowed literally anything . concrete thing happened was, there binary garbage in memory space allocated pathname , , strcat cheerfully treated string, contents of...

i have java code: numberformat nf = numberformat.getnumberinstance(locale.getdefault()); decimalformat df = (decimalformat)nf; newcurr = df.format(dcurr); basically, pass in number, 12.344. i want rounded 2 places , use locale's default separator (either "." or ","). so, example in countries in europe, want 12,34 so far code above, halfway there. 12,344. can't find place decimalformat of ("#.##") can rounded. in other words, can incorporate decimalformat df=new decimalformat("#.##"); in above? or have find way? edit: thinking have old way of (100.00 * var)/ 100.00 , pass in? the method setmaximumfractiondigit work. see rest of available methods: http://docs.oracle.com/javase/7/docs/api/java/text/decimalformat.html#setmaximumfractiondigits%28int%29
