C/C++ Programming: String Parsing

Recommended Posts

Problem: Write C/C++ code to parse a given sentence ( which is called String in C/C++ world ) "Test1:Test2:Test3" by character semicolon ':'.

Solution should be:

First String: Test1

Second String: Test2

Third String:Test3

 

Code:

#include<stdio.h>

#include<stdlib.h>

#include<string.h>

 

void parse( char* buffer, char ch )

{

char firstString[100], secondString[100];

int address1,address2, strlen;

char* pdest,*predest;

pdest = strchr( buffer, ch );

if( pdest != NULL ){

address1 = (int)buffer;

address2 = (int)pdest;

strlen = address2 - address1;

if( strlen <= 0 ) { printf("Oooopps fuked up."); return;}

strncpy( firstString, buffer,strlen );

firstString[ strlen ] = 0;

printf("First String:%s\n", firstString );

pdest++;

predest = strchr( pdest,ch);

if( predest != NULL){

address1 = (int)pdest;

address2 = (int)predest;

strlen = address2 - address1;

if( strlen <= 0 ) { printf("Ooooops fuked up."); return;}

strncpy( secondString, pdest,strlen );

secondString[ strlen ] = 0;

printf("Second String:%s\n", secondString );

//Extract the last string now

predest++;

printf("Third String:%s\n", predest );

}

}

}

 

 

void main( void )

{

parse("Test1:Test2:Test3",':');

}

Its so intresting RS g .. . .

I'm so glad to see RS g here. . . anyway C is one of the most important software to devlop to hardware. So RS g i've made one simple program about using one diode where i've used max 10v with 2-0e+00 time constant in graphic mode. U can find here the specially current with fordward bios. So anyone u can make RC/RLC circuit to using C in graphic mode.

 

 

#include <stdio.h>

#include <stdlib.h>

#include <float.h>

#include <graphics.h>

#include <math.h>

#include <conio.h>

 

 

#define PI 3.14159

 

typedef char string[bUFSIZ];

void Diode_response();

void Diode_grapic();

void makegraph();

void box_draw();

 

float ID[500];

 

 

int main(void)

{

char ch;

Diode_response();

printf("\n \n Do u want to open in Graphic mode[yes:y]? or no[no=n)?");

ch=getch();

if(ch=='y')

{

Diode_grapic();

}

ch=getch();

if(ch=='n')

return(0);

}

 

 

void Diode_response()

{

int i;

float k,VD;

k=11600.;

for(i=1;i<300;i++)

{

VD=(float)i/500.;

ID=(exp(k*(VD)/(27.+273.)))-1;

}

 

}

 

void Diode_grapic()

{

int g_driver, g_mode,i;

int P_time,P_data,x_pixsel,Y_axis,Max_point,P_data_1;

float Y_max,X_max,Vc,X_point,Vr1,Vc1;

 

Max_point=500; //ÃÖ´ë pixel point

 

detectgraph(&g_driver, &g_mode);

initgraph(&g_driver, &g_mode, "..\\..\\bgi");

cleardevice();

box_draw();

outtextxy(200,10,"DIODE Timeconstant response");

 

// Vr, Vc bata current measuring

 

for (i=1;i<300;i++)

{

setcolor(14);

if(ID/10000.>240.) break;

line(i+50,300-(int)(ID/10000.),i+51,300-(int)(ID[i+1]/10000.));

}

 

 

// Ãà ½ºÄÉÀÏ °è»ê

Y_max=10; //y max value

 

//yÃà ½ºÄÉÀÏ

 

for(i=0;i<6;i++)

{

gotoxy(3,4+i*3);

printf("%2.1f",Y_max-(Y_max/5)*i);

}

 

//xÃà ½ºÄÉÀÏ

X_max=2;

 

for(i=0;i<12;i+=2)

{

X_point=i*X_max/10;

gotoxy(6+i*6,20);

printf("%1.1e",X_point);

}

 

getch();

closegraph();

}

 

 

void box_draw()

{

int i;

//x ÃàÀ¸·Î ¼± ±ß±â

setcolor(8);

for(i=50;i<550;i+=10)

{

line(i,50,i,300);

}

setcolor(7);

for(i=50;i<550;i+=50)

{

line(i,50,i,300);

}

// y ÃàÀ¸·Î ¼± ±ß±â

setcolor(8);

for(i=50;i<300;i+=5)

{

line(50,i,550,i);

}

setcolor(7);

for(i=50;i<300;i+=50)

{

line(50,i,550,i);

}

 

// »ç°¢Çü ±×¸®±â

setcolor(10);

rectangle(50,50,550,300);

}

 

//(When u check this program, u've to change in graphic mode ur c complier)

Bohara,,i didnot even see ur post until today..wow ( after so many months),,i will definitely need to check out ur code,,and i will change the graphic mode of my computer before i try it. thanks..post some more and give info on any electronic projects u r working on.

Hi guys,

 

help me a little...I've got a program and i don't lnow how to make it.

The program is:

Enter a sequence of numbers (it can be negative(with -)) which end will be marked 0.Print the amount of numbers,which begins with same numbers.For example: 2334,3453,121,6456 the answer will be 3.

 

Thanx a lot.

 

Andrew

I've made a mistake there...sorry.

Andriuxa,

i have some psuedocode for u,,see if u can write code from there, if not i will help u.

 

//Global variable

totalNumofSameNumber = 0

do {

firstNumber = 0

lastNumber = 0

while ( entry is not 0 ){

Enter a number

determine this is the first number or not,, if it is remember the number

firstNumber = this number

determine this is the last number or not, if it is last number, compare

lastNumber = this number

if( firstNumber == lastNumber ) totalNumofSameNumber++;

}

 

Write next sequence of numbers. Y or N?

while ( write next sequence == Y )

}

hm...interesting but I don't understand sad.gif

Friends told me to do this program using procedure (string and massive),but I don't know how to work with string :/ I've read about it,but... sad.gif

I am 1 course student...it is a little bit difficult for the first time to understand everything at one time...and a lot of task to do...need more time :/

 

Tell me how to write or write it if you can,please.

Thanks.

Hi,

 

You have a very cool Forum here…loved the content.

I have a question..

- “Seeking experienced programmer with following skills: strong browser UI background, specifically in JavaScript, AJAX, CSS, HTML. Also must have good system & software design skills, e.g. OOP. C++/C knowledge a plus”

 

I came across this site called Myndnet.com where u get paid if u answer this question.

It’s a platform for people to buy and sell Technology related information. Good money for people like us in the IT domain.

Here the link http://www.myndnet.com/login.jsp?referral=...amp;channel=A63

You can contact me at my id here for more questions : barot.alpa@gmail.com

 

Cheers :)
