So I have a char array, c, which has characters like this: "HELLO MY NAME"
I want to make a char pointer array, *pCar, so that pCar[0] will have HELLO and pCar[1] will have MY and pCar[2] will have NAME.
I have something like this but it doesn't work.
for (i = 0; i < 30; i++)
{
pCar[i] = &c[i];
}
for (i = 0; i < 30; i++)
{
printf("Value of pCar[%d] = %s\n", i, pCar[i]);
}
As suggested by @JoeFarrell, you can do it using strtok():
char c[] = "HELLO MY NAME";
char *pCar[30]; // this is an array of char pointers
int n = 0; // this will count number of elements in pCar
char *tok = strtok(c, " "); // this will return first token with delimiter " "
while (tok != NULL && n < 30)
{
pCar[n++] = tok;
tok = strtok(NULL, " "); // this will return next token with delimiter " "
}
for (i = 0; i < n; i++)
{
printf("Value of pCar[%d] = %s\n", i, pCar[i]);
}
What strtok() does is it replaces de delimiters in your original string with a null-character ('\0'), that marks the end of a string. So, at the end you get:
c ─── ▶ "HELLO\0MY\0NAME";

pCar[0] ─┘ │ │
pCar[1] ────────┘ │
pCar[2] ────────────┘
