Array of pointers

**automagp68** · 06-02-2012

Hi guys

Its been a while since i did some see

I just want to let the user enter in a few strings in store them in an array of pointers. Which each pointer pointing to the begining of a different string.

Its been a while and i barley remember how. Here is what i got some how but it doesnt seem to work. Any suggestions?

Thanks

Code:

#include<stdio.h>
#include<stdlib.h>



int main (){


char *pointer[3];

printf("Please enter the string you want to deal with");

    scanf("%s"pointer[0]);


printf("This is what we just stored there %s \n\n",pointer[0]);








return 0;

}

Allocate space for the input to be placed into.
Either use malloc type functions or declare char arrays to hold the data.
Or, use a mixture of the two.

Ok i think this is where i lost

I have done what you suggested many times but it requries a char array for every single string. Meaning i now need n number of arrays per string

Is there any way to avoid this?

Just declare one array a pointer array and have it point to the strings.

Like i know you can have a 2 dem array and the array stores all the strings so i dont need a bunch of char strings?

Read this link about arrays!

Decide if you want to use malloc or not. Then, state your answer!

It sounds like you have not done as suggested at all as it does not require you to make any char arrays.

Or if you're quibbling over multiple calls to malloc, what's the difference if it all works and takes very few lines of code?
Sure, you could make just one call to malloc and plonk every string back to back in that memory block, but if you wanted to say make one of the strings longer afterwards then that isn't any good.

Just post code for what you're trying to do. It doesn't matter if it crashes, just at least try and get it to compile, unlike what you posted already.
