Load numbers from text file in C [closed]

Answer 1

You can:

1) Read one number at a time and convert to int using atoi()

2) You can read the whole array at once and using strtok to divide the number and after that convert with atoi()

Here there is an example of strtok:

  int main(int argc, char *argv[])
{
        int x = 1;
        char str[]="this:is:a:test:of:string:tokenizing";
        char *str1;

        /* print what we have so far */
        printf("String: %s\n", str);

        /* extract first string from string sequence */
        str1 = strtok(str, ":");

        /* print first string after tokenized */
        printf("%i: %s\n", x, str1);

        /* loop until finishied */
        while (1)
        {
                /* extract string from string sequence */
                str1 = strtok(NULL, ":");

                /* check if there is nothing else to extract */
                if (str1 == NULL)
                {
                        printf("Tokenizing complete\n");
                        exit(0);
                }

                /* print string after tokenized */
                printf("%i: %s\n", x, str1);
                x++;
        }

        return 0;
