C++ :: Can't Get Length Of String

Nov 20, 2013

I'm trying some codes about string arrays and taking array length. But i have some problems. I can't get length of string and can't send to a function.

------------------------
#include<iostream>
#include<cstring>
#include<string>
using namespace std;
void GetLength(string);
std::string Words[]={"table","gun","programming"};
int main()
{std::string InputWord;

[Code]...

And how can send Matrix to other function?

C++ :: Can Get Length Of Integer?

Oct 3, 2013

The programming problem is supposed to take a decimal number from a user and turn it into a binary number. Here is my code:

for (int i=0; i< count; i++) {
binary[i] = decimal % 2;
decimal = decimal/2;
} cout << binary[2] << endl;

decimal is the number entered by the user.

binary [] is the char array and count is... you know how many times the for loop will turn. So my question is, how do i know the length of the number ? Any function that shows the integer length ? because its impossible to know what count is equal to. like 100 is 3.

C++ :: Find Every Permutation With Length From 1 To N?

Jan 29, 2015

I need to be able to find every possible permutation using all possible values of a char. But I have to make it be able to form permutations from a length of 1 to variable N. For example, if N=3, I need it to be able to come up with

0x00
0x01
.......
0x00 0x00
0x01 0x01
.......
0xff 0xff 0xfe
0xff 0xff 0xff

How could I do this. (I would like to avoid recursion, since N might be as large as 50 or 60 and using recursion would most likely cause a stack overflow)

C :: How To Determine Length Of Array

Apr 16, 2013

I'm working with arrays that might have NULL bytes in them and I'm wondering how to determine the length of the array or store it somewhere with the array (strlen() won't work because of the NULL, right?).

I've found advice like store the length of the array in the first byte of the array, but since sizeof(size_t) is 8 should I leave the first 8 bytes for the length?

Would it be better do define my own structure which would store the array and its length? What's the usual way these things are handled in practice?

C :: Exceed Array Length

Feb 9, 2014

I was reading in a book I had about C that an array has at the very end a "null character" signifying the end of the string inside it, "/o". So that made me think, "I guess one needs to declare arrays as having 1 extra space than one expects the array to need. I wonder what will happen if I exceed the array length?" So I made a program to test it out. Here is the program/results:

Code:

#include <stdio.h>
int main(void){
char name[3];
printf("
What's your name?
");
scanf("%s", name);
}

[code]....

As you can see my name was able to fit in the array somehow even though I only allocated 3 bytes to the array. I tried again using my legal first name, Benjamin, and it was still able to fit. How is the array able to hold my name when I declared it as only having 3 bytes?

C++ :: Length Of String Array?

Sep 7, 2013

I can't find any method of retrieving the length of an array except for doing this:

string first[] = {"a","be","see"};
int length = sizeof(first)/sizeof(first[0])

This is a very unconventional way of getting the length of an array.

first->length() would return 1 because it returns the number of letters in the first element of the array (which actually makes no logical sense).

first.size() would return 1 aswell as it's practically the same thing.

Since getting the length of an array is such a fundamental feat, how come I can't find a decent method of doing it?
Is there no buildt in method for this? If there is not, why has it not been implemented in the std?

C++ :: How To Set Fixed Length For String

May 28, 2013

The input consists of one or more packets followed by a line containing only # that signals the end of the input. Each packet is on a line by itself, does not begin or end with a space, and contains from 1 to 255 characters.

it said 1 to 255 characters

i have to use getline(cin,str);

i tried str[255] but some error happen

C/C++ :: Find Length Of String

Dec 15, 2014

I am stuck here.

printf(" Enter a line of Morse Code for decrypting");
scanf("%s",phr);
len=strlen(phr);
for(a=0;a<36;a++) {
if(strcmp(phr, morse[a])==0)
printf("%c", alpha[a]);
};printf(" ");

The output :

[output] Enter line to encrypt:
..... -.... --...

converting...
5 [/output]

It should read all code, including null. between coded letter one space, between coded word three spaces.

The output should be:

[output]
56 7 [/output]

C/C++ :: The Length Of EditBox In Win32

Feb 15, 2014

That is my routine to catch a text from editBox (ID_EDIT2) and save in a file. The address of file is in (ID_EDIT1). The code is working.

void simplewrite(HWND hwnd){
HANDLE hFile;
DWORD dwWritten;

[Code]....

My problem is: I put the size of char array txtbuffer=[200]. If I have a editbox bigger than that, I'll get a error. In (editlength) I have the correct length of edit box. But I cant initialize my char txtbuffer[editglenth]=NULL cause editlength is a integer not constant.

C :: How To Save Returned Of Unknown Length

Sep 15, 2014

I call a function that returns a string, and I can print it out fine, but I want to test the result of the function to see if it returns 0. But I can't just call the function again (GetNextToken(b)) because it will generate a different token. I can't allocate space for the string because I'm not sure what the size of the returned string is going to be.

Basically I want to see if the GetNextToken(b) returns 0, and if it doesn't then print the string. And running GetNextToken(b) again will give a different result.

Code:
int main(int argc, char **argv) {
SomeStruct* b = CreateStruct(argv[1],argv[2]);
printf("HERE %s", GetNextToken(b));

C :: Word Length Statistics For A Sentence

Oct 25, 2014

Write a program that calculates statistics on word length for a sentence. The sentence isterminated by a ',' For each found length of a word the number of words of that length is printed. Only those lengths that are found in the input are printed. Only letters from a-z or A-Z are allowed to form words. Words are separated by a space. No punctuation characters other than ',' are allowed. If any other input character is recognized or the input is longer than 80 characters the program displays "NOT VALID" (see Hints).

Note, that in the case that no word is present in the input, nothing is printed.

% u6_stats

Enter a sentence: Bolt was expected to use the super bark.

Length 2: 1
Length 3: 3
Length 4: 2
Length 5: 1
Length 8: 1

% u6_stats

Enter a sentence: Something wasn't right.
NOT VALID

Thats what i've already done.

Code:
#include <stdio.h>
#include <conio.h>
void main() {
char s[100];
int numOfWords, lengthOfWord = 0;

[Code] ....

So, the problem is that if i inpute a text like"abc abcd abc abc" the result will be like

"length 3: 3 length 4: 1 length 3: 2".

So when the program already compared 1st (here 3) element with others, this element will not be comparing again, but i have the 3d element with same length, and it that case, the program compare it with remained elements and print 2. How can i rework my code, if i don't wont to compare already compared elements.

Second problem is that i need to get results from lowest length till highest.

C :: Creating Variable Length Arrays

Oct 24, 2014

How do you prompt the user to enter the number of elements for the array and use that information to creatr a variable length array? And then how do you prompt the user to enter in a number for each element of the array and scan in the appropriate numbers? the numbers are double precision floating point.

for example,
Enter the numbe of elements in the array: 3
Enter element 0: 3
Enter element 1: -1
Enter element 2: 4

I know it starts with

int main() {
double N;
int a[size];

printf("Enter the number of elements in the array:" );
scanf("%f", &size);

//I'm pretty sure this is wrong

C :: Why To Set Length Of Inner Arrays Declaring A Function

Oct 23, 2013

I'm just wondering, why you have to set the length of the inner arrays declaring a function. In which moment does the code needs to be sure about the length of the inner arrays accessing an cell?

I came up with this question realizing the elements of the outer array beeing pointers to the first value of each inner array. Therefore I can access e.g. the first first element of the second inner array like this:

**(arr + 1) ...regardless of the length of any array to my mind.
