C/C++ :: Print Dynamic String To Console Tokenized Using Spaces As Delimiters

Feb 26, 2014

I am having some trouble tokenizing some strings in C. I am trying to take in a string dynamically and spit print it to the console tokenized using the spaces as delimiters. I have tried using frets() and scant() as well as playing around with pointer values to no avail.

#include <stdio.h>
#include <unistd.h>
#include<string.h>
#include <stdlib.h>
#define MAX_LINE 80
//function prototypes
void printArgs(int argc, char* args[]);

C :: How To Use Multiple Delimiters On A String

Mar 19, 2013

This is part of a bigger program im working on that deals with data structures, but I'm trying to figure out a way to tokenize a long file of purchases that is being read to my program. I rewrote the program to pinpoint my problem. I need to get the name, cost, item and quantity from this string. I figured out how to look for the cost, but what about the name and item(shirts)? How can I do this all in one loop because there are multiple strings and i'm gonna eventually send all the info to a data structure for each person(name)? I'm only asking about the tokenizing part, but this code works for the cost.

Code:

int main(void) {
char myString[] = "Angela bought 9 shirts for $6 each." ;
char * del = " " ;
char * token ;

C++ :: Dynamic Memory (array Of Char) - Delete All White Spaces In Text File

Feb 8, 2014

General Purpose: Delete all "white spaces" in text file, until the read-in char is _not_ a whitespace (mark as start of text file).

Problem: Cannot seem to shift char's over properly. (I think my problem is the inner loop - however other code may lead to this problem - I do not know)

Code:

#include <fstream>
#include <iostream>
using namespace std;

bool trimWhiteSpace(fstream &file, char * charMemoryBlock) {
if (!file.is_open()) {

C/C++ :: Using Printf Statement To Print Certain Number Of Spaces

Sep 1, 2014

is there a to use printf to print certain number of blank spaces, where the number is derived from the output of a function?

for(m=low; m<=high;m++)
{
printf("t=%2d %'f(m)-1's %3c
", m, ' ',*);
}

this is suppose to output

t=-3 *
t=-2 *
t=-1
.
.
.

This is supposed to output t=m and then m is plugged into a function say for -3, plugging it into function f gives 23, well i want 22 blank spaces and then a asterik and go to next line. that is why i put -1 after %'f(m)-1's i

The asterisk appear right next to the t value here but they are way to the right of it when i made this post.

C# :: Finding A String Starting With Spaces Within Another String

Sep 8, 2014

I need to find a string with leading spaces like " target sting" inside another sting.

And I need to find something like "target sting" inside another sting.

I used .IndexOf() but noticed it ignores leading spaces.

So then I went with .Substring() but that doesn't seem like that's the best solution either.

C++ :: Searching Through Entire String Looking For Spaces / Punctuation

Dec 11, 2014

I have it searching through the entire string letter by letter, looking for spaces, punctuation, etc... yet it still is continuing on with the space.

#include <iostream>
#include <iomanip>
#include <fstream>
#include <string>
#include <stdio.h>
#include <cctype>
#include <algorithm>

[Code] ....

Output:
if(str_word == " ")
//or
if(str_word == ' ')

It does nothing to change it. I am completely baffled.

I need to read the id numbers into an array, the grades into a 2d array and the names into a 2d c-style string arrays.

But i'm having trouble getting past the delimiters

This is what i'm trying but it doesn't work

I have to print to the screen the id numbers, the grades and the names

I'm using getline but im having trouble print out the grades

It gets and displays everything except the grades. One of the grades only gets displayed

It should be a while loop, but im just working with the first line for now

ifstream inf;
char fileName[ MAX_STR_LEN ] = "ex.txt";
char testStr[ MAX_STR_LEN ];
int testInt;
double testDouble;

C :: Creating Dynamic String?

Mar 6, 2015

Code:

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <stdarg.h>
char * form(char *format, ...);
}

[code]...

So, this is the code i have problem with, as far as i can see, function form actually does the same thing that printf does.It probably puts all of the arguments sent to the function together into one string.

C :: Dynamic Array Of Pointers To String

C :: Dynamic Allocation Of String Pointers

Mar 12, 2014

The snippet below (or similar) compiles and runs OK but I am using Visual Studio C++ compiler. Are the lines where .nameFirst and .nameLast assigned kosher in ANSI C?

Also I am concerned about the memory allocation for these string constants. Does the runtime system put them on the heap? It doesn't seem that they are really constants since they are not defined before runtime.

Code:

#include "stdlib.h"
typedef struct
{
unsigned id;
char* nameFirst;
char* nameLast;
} myList;

C++ :: Dynamic Allocation For String Array

I have used dynamic memory allocation technique and its working fine for all strings without consecutive same alphabets.I use a list in which a string is placed in its exact position by moving the others right.

#include <stdio.h>
#include <string.h>
#include <math.h>
#include <stdlib.h>
#include <conio.h>
