i need help.
i need to write a code that can extract word from string.
i had use cin.getline(string,size) to get th string and strtok(string," ") to extarct token. now i want to know how can i insert the token in array because i want to use the token for other purpose.

this what i had write

const size=100;
char string[size];
char *tokenPtr;
cout<<"string\n";
cin.getline(string,size);
tokenPtr =strtok(string," "); //bring string1 by separated by characters in string2

while (tokenPtr != NULL)
{
cout<<tokenPtr<<"\n";
tokenPtr=strtok(NULL," ");
}

i had come across function strcspn, and i want to know how it work.

please give me some idea?
thank your.

i had a error---> cannot convert char * to char when i write this code as below

while (tokenPtr != NULL)
{
cout<<tokenPtr<<"\n";
temp[i]= tokenPtr;//tokenPtr was declare as a pointer
i++;
tokenPtr=strtok(NULL," ");
}

i had change to code to this
while (tokenPtr != NULL)
{

temp[i]=* tokenPtr;
i++;
tokenPtr=strtok(NULL," ");
}

for (int j=0;j<i;j++)
{cout <<temp[j]<<"\n";
}

the input was i need help
but only show first character of the word as
i
n
h

how can i get the output like this
i
need
help

i think i had got it.it works

here is the code

#include <iostream.h>
#include <string.h>

int main()
{
//declaraction variable
//----------------------------
const size=100; //size of string
char string[size],temp[size][32];
char *tokenPtr;
int i=0;

cout<<"input string\n";
cin.getline(string,size);//read line of string

/*function char *strtok(char *s1,const char *s2) breaks s1 into token(word)
separated by character in s2
*/

tokenPtr =strtok(string," ");//pointer to first token

while (tokenPtr != NULL)
{
strcpy(temp[i],tokenPtr);//save the token to array
i++;
tokenPtr=strtok(NULL," ");
}

for(int j=0;j<i;j++)
{
cout<<"temp["<<j<<"]="<<temp[j]<<"\n"; //write the token
}
cout<<"\n\n0 for exit\n";
int b;
cin>>b;
if (b==0)
{return 0;}
}

i try to input string like--> here i go
then output show as below

temp[0]=here
temp[1]=i
temp[3]=go

let me know if there a simple or other way to get the program run..

thank you

now..just need to think how to compare the token(word) with word in the file.txt that contain many word.
wish me luck

here the code

same as below,but now the code in the tags..
thank you
