Split string into char array

Expand Post »

Hi, I was wonder if someone could give me some help with my program

I have a variable:

char *insert = "abcdefgh"

and i want to split that into chars like so, 'a', 'b', 'c', 'd', etc.

I've tried ToCharArray(), but that doesnt seem to work

Uh, you're done. A string literal is an array of const char and except for modification, sizeof, and address-of you can use the pointer as if it were an array. If you need an actual array, you can do this:

c Syntax (Toggle Plain Text)
char insert[] = "abcdefgh";
char insert[] = "abcdefgh";

C doesn't have a special string type like Java, so when you're using a string in C, you're really using an array.

a string in c/c++ is a array of characters so extract then like so

#include <iostream>

int main(int argc, char**argv)
{
char *insert = "abcdefg";

for (int i = 0; i < 7; ++i)
std::cout<<insert[i]<<"\n";

}

Re: Split string into char array

This is C forum. Not C/C++

Take the time to read how properly tag your code so instead of looking like this:
#include <iostream>

int main(int argc, char**argv)
{
char *insert = "abcdefg";

for (int i = 0; i < 7; ++i)
std::cout<<insert[i]<<"\n";

}

It would look like this:

CPP Syntax (Toggle Plain Text)
#include <iostream>
 
int main(int argc, char**argv)
{
    char *insert = "abcdefg";
 
 
    for (int i = 0; i < 7; ++i)
    std::cout<<insert[i]<<"\n";
 
}
#include <iostream>

int main(int argc, char**argv)
{
    char *insert = "abcdefg";


    for (int i = 0; i < 7; ++i)
    std::cout<<insert[i]<<"\n";

}

For how to do that read here and here
I don't promise that it'll fix your code, but it'll make it more readable.

If you're not sure, don't answer because you're more likely to lead people astray with bad advice than do any good.

>hee hee
Oh, I get it. You're joking. Because anybody who would jump into a thread over a year after it unofficially ended and offer something as inane as your "help" is either trying to get a laugh or is a complete retard. I don't think you're a complete retard (yet), so it must be a pitiful attempt at humor.

Re: Split string into char array

If you really want to make an array of char without '\0' at the end of it. You could make something like this

C Syntax (Toggle Plain Text)
#include<stdio.h>
 
int main()
{
char *insert = "abcdefgh";
char outsert[8]; //I use 8 because abcdefgh contains 8 char
int i;
 
for (i=0;i<8;i++)
{
outsert[i] = insert[i];
}
 
return 0;
}
#include<stdio.h>

int main()
{
char *insert = "abcdefgh";
char outsert[8]; //I use 8 because abcdefgh contains 8 char
int i;

for (i=0;i<8;i++)
{
outsert[i] = insert[i];
}

return 0;
}

But i can't imagine what you only can do with array of char. Please answer me.

you can do like this: char[] values = {'a','b','c','d','e','f','g'};
then address to each value using the vector(array) like this:

values[0],values[1],etc. (a,b,etc.)
you might want to see this tutorial that has also some detailes about char array: http://goldwin-advertising.ro/index....howto&Itemid=5

Yeah they probably figured that out 3 years ago when the question was posted.

Re: Split string into char array

char str[] = "now # is the time for all # good men to come to the # aid of their country";
char delims[] = "#";
char *result = NULL;
result = strtok( str, delims );
while( result != NULL ) {
printf( "result is \"%s\"\n", result );
result = strtok( NULL, delims );
}

OUTPUT:
result is "now "
result is " is the time for all "
result is " good men to come to the "
result is " aid of their country"
