Thread: Entering and splitting string

fflush(stdin) is undefined - read FAQ.
gets is unsafe. Use fgets instead.

You can strtok() it into
Name1 20
Name2 30
and so on
Then strtok() each of those into the names and ages.
Don't use fflush(stdin);
Also, system("cls"); is not secure

system itself is unportable (due to that it simply executes OS specific programs), and how to clear the screen is also covered in the FAQ.

One way would be to use a pointer to keep track of the position in your buffer, then search for ' ' or ',' and from that, extract the strings using memcpy.

Here's some psuedocode of how I'd solve this problem:

Code:

struct PERSON
{
    char name[MAX];
    int age;
};

/************* inside the main() function *************/
char data[MAX], name_and_age[MAX];
PERSON names_and_ages[MAX];
// Get the input
count = 0;
while (GetMoreData(data, name_and_age))
{
    names_and_ages[count] = SeparateNameAndAge(name_and_age);
    count++;
}

// The GetMoreData function:
bool GetMoreData(char data[], char name_and_age[])
{
    name_and_age = strtok(data, delim);
    // if strtok didn't work return false

    return true;
}

// The SeparateNameAndAge function
PERSON SeparateNameAndAge(char name_and_age[])
{
    PERSON person;
    // strtok the name: person.name
    // strtok and convert the age: person.age
    return person;
}

Declaring variables in the middle of a block is C99 and should be avoided in C89 programs. In addition, casting malloc() is generally a bad idea.

Here's one way to do it, with sscanf().

Code:

    char delims[] = ", ", *result = NULL;
    char name[MAX];
    int age;
    result = strtok(data, delims);
    while(result != NULL) {
        sscanf(result, "%s%d", name, &age);
        printf("Name: %s\tAge: %d\n", name, age);
        result = strtok(NULL, delims);
    }

Yes, of course, sorry, I forgot to eliminate the space from the list of delimiters. Here's a full working example.

Code:

#include <stdio.h>
#include <string.h>

void splitname(char *string) {
    const char *delim = ",", *next;
    char name[BUFSIZ];
    int age;

    for(next = strtok(string, delim); next; next = strtok(NULL, delim)) {
        sscanf(next, "&#37;s%d", name, &age);
        printf("Name: \"%s\", age: %d\n", name, age);
    }
}

int main(void) {
    char data[] = "Joe 10, Sam 20, Tim 40, Buckministerfullerine 80";

    splitname(data);

    return 0;
}

Output:

Code:

Name: "Joe", age: 10
Name: "Sam", age: 20
Name: "Tim", age: 40
Name: "Buckministerfullerine", age: 80

Well, it's not that much different from dealing with ages (numbers). You have to use a multi-dimensional array, however, much like this:

Code:

int numberarray[ELEMENTS];
char stringarray[ELEMENTS][MAX_STRING_LENGTH];

And when sorting strings, you need to use strcmp() to determine which string comes "before" another string.

Try it out, see what happens. Get the number (age) code working first, and it should be a simple modification.

Use strcpy().

Code:

strcpy(names[c], the_latest_name);
c ++;

Or something like that.

And don't forget to #include <string.h>.
