I am writing a program where the user inputs a string, and then that string is evaluated by the program word by word, but there is one problem, how do I break it down word by word, (i am also going to use vectors), -Brett
Look at man pages for this function for extracting tokens from string strtok, strtok_r the sytax is char *strtok(char *str, const char *delim);
Yes, this does work, but, how do I get Input from a user and evaluate that, not just a given statement already in the code? #include <stdio.h> #include <string.h> int main () { char str[] ="- This, a sample string."; char * pch; printf ("Splitting string \"%s\" into tokens:\n",str); pch = strtok (str," ,.-"); while (pch != NULL) { printf ("%s\n",pch); pch = strtok (NULL, " ,.-"); } return 0; }
the prototype of fgets() is: char *fgets( char *str, int num, FILE *stream ); you should do: char buffer[100]; ............. fgets(buffer,sizeof(buffer),stdin); to take input from user.
