    Question Array of Strings

    Can somebody tell me how to create an array of strings and load the strings into the array. I know how to use arrays with integers or even floats but not with strings.

    char array[NUM_OF_STRINGS][MAX_LEN_OF_A_STRING];
    And don't forget room for the null terminator.

    then, to populate one element:
    strcpy (array[0], "Some text");

    There are other ways too.
    When all else fails, read the instructions.
    If you're posting code, use code tags: [code] /* insert code here */ [/code]

    Hi,
    You can use char *names[MAXNAMES] also..

    Provided you're using string literals and don't intend on making modifications. Otherwise you also want to throw some dynamic memory allocation in there as well. Treating an uninitialized pointer as a string rarely works.
    My best code is written with the delete key.

    It's a must to get array of strings work.

    Not if you use an array of arrays as Hammer described.

    Code:
    #include <stdio.h>
    #include <stdlib.h>
    #include <string.h>
    
    #define MAXNAMES 5
    
    int main(void)
    {
        char buffer[1024], *str_arr[MAXNAMES];
        int i;
    
        for (i = 0; i < MAXNAMES; i++)
        {
    	fgets(buffer, sizeof buffer, stdin);
    
    	str_arr[i] = malloc(strlen(buffer) + 1);
    	if (str_arr == NULL)
    	    perror("malloc"), exit(EXIT_FAILURE);
    
    	strcpy(str_arr[i], buffer);
        }
    
        return EXIT_SUCCESS;
    }

    >>if (str_arr == NULL)
    is incorrect, it should be
    >>if (str_arr[i] == NULL)
