string - How to obtain a substring based on index in C -

-

for background, i'm not familiar c, i'm proficient in java. in current program i'm working on, i'm trying figure out how implement java method somestring.substring(int startindex, int endindex) returns new string based on starting , ending index of previous one.

for purposes of implementation, cut first char off , return remaining string. here's implementation in java.

public string cut_string(string word) {      string temp = word.substring(1, word.length());     return temp; }

use this

#include <stdio.h> #include <stdlib.h>  char* substring(char*, int, int);  int main()  {    char string[100], *pointer;    int position, length;     printf("input string\n");    gets(string);     printf("enter position , length of substring\n");    scanf("%d%d",&position, &length);     pointer = substring( string, position, length);     printf("required substring \"%s\"\n", pointer);     free(pointer);     return 0; }  /*c substring function: returns pointer substring */  char *substring(char *string, int position, int length)  {    char *pointer;    int c;     pointer = malloc(length+1);     if (pointer == null)    {       printf("unable allocate memory.\n");       exit(1);    }     (c = 0 ; c < length ; c++)    {       *(pointer+c) = *(string+position-1);             string++;       }     *(pointer+c) = '\0';     return pointer; }

i wish write custom appender on basis of outputstreamappender . wrote following class package tests; import java.io.ioexception; import java.io.outputstream; import ch.qos.logback.core.outputstreamappender; public class myappender<e> extends outputstreamappender<e> { public myappender() { system.out.println("myappender created"); setoutputstream(new outputstream() { @override public void write(int b) throws ioexception { throw new unsupportedoperationexception(); } }); } } then wrote following runner: package tests; import org.slf4j.loggerfactory; import ch.qos.logback.classic.logger; public class runner { private static final logger log = (logger) loggerfactory.getlogger(runner.class); public static void main(string[] args) { //log.addappender(new myappender<iloggingevent>()); log.info("hello world"); } } finall...

java - UML - How would you draw a try catch in a sequence diagram? -

is there standard way of drawing try catch sequence diagrams? i've made attempt based on this feel end result doesn't feel right. code diagram based around: public static void save () { try { filehandle filehandle = gdx.files.external(file); filehandle.writestring(boolean.tostring(constantshandler.soundenabled)+"\n", false); (int = 0; < 5; i++) { filehandle.writestring(integer.tostring(constantshandler.highscores[i])+"\n", true); } } catch (throwable e) { } } my attempt note: know still need add loop. that's ok. fragments meant show conditional control flow in sequence diagram. superstructures puts limitations on use of fragments (see pp. 467 of ss2.1.1). should use critical region try part above. , option catch . however, keep telling can take quite freedom in using uml. it's language , such changes in life time. long reader ge...
