Body
I'm making a program that takes names from the user seperated by commas. The program allows the user to put as many or as little spaces as they want between the commas. So for example: If I were to type something like <pre><code>Smith, John </code></pre> or <pre><code>Smith,John </code></pre> I would want to print out <pre><code>John, Smith </code></pre> The thing is though my program does not properly process the following examples above; it works if the input was something like <pre><code>Smith , John </code></pre> or <pre><code>Smith ,John. </code></pre> Here is my code: <pre><code>#include <stdio.h> #include <string.h> #include <ctype.h> #define LINESIZE 128 int get_last_first(FILE *fp); int main (void) { get_last_first(stdin); } /*takes names in the format [LASTNAME],[FIRSTNAME]*/ int get_last_first(FILE *fp) { char first[LINESIZE]; char last[LINESIZE]; char line[LINESIZE]; size_t i; while(1) { printf("Enter your last name followed by a comma and your first name\n"); /*if we cant read a line from stdin*/ if(!fgets(line, LINESIZE, fp)) { clearerr(stdin); break; /*stop the loop*/ } /*goes through the line array and checks for non-alphabetic characters*/ for(i = 0; i < strlen(line); i++) { if(!isalpha(line[i])) { /*if it sees a space hyphen or comma, it continues the program*/ if((isspace(line[i]) || line[i] == ',') || line[i] == '-' ) { continue; } else { return -1; } } } if(sscanf(line, "%s , %s", last, first)) { printf("%s, %s", first, last); return 1; } return 0; } } </code></pre> Is it because I am not using sscanf properly?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
