Need some basic help

Beginner · 10-31-2001

I started studying C today, read one book, and I tried to do something myself, immediately run into problems...
Okay, I'm trying to do two things here...

How to make program enter full names?

I made a program where you enter names and it is supposed to list them and it says:

Enter 1st name: John McMutton
Enter 2nd name Enter 3rd Name:

So what it does, it works fine only with part John, but when I'm trying to add the space, it screws up, how do I do it right?

Secondly, I tried to make clock time...
Lets take 24 hours, not PM or AM thingie...

I want to know how to make program that counts times like:
13:00 - 15:00 = 2h or 8:00 + 23:45 = 8.15

Thanks already

The name code:

#include <stdio.h>
void main(void)

{
char name[7][15];
int i;
printf("\n");
for (i= 0; i <= 6; i++ )
{
printf("Give %d. name: ", i +1);
scanf("\n %s", name[i]);
}
printf("\nNames were: ");
for( i = 0; i <= 6;i++)
printf("\n %s", name[i]):
}

that was the name code...

i have no idea how to make the clock thingie...

You read the wrong book, if it told you to do this
> void main(void)
main returns an int.

When you do this, add
  return 0;
to the end of main

Fix the scanf call like so
scanf("%s", name[i]);

Later - do this first

Sorry if I'm getting on your nerves...
exactly where i should add the return 0; ?

**Salem** · 10-31-2001

Code:

int main ( ) {
    // all your code
    return 0;
}

Still saying the same thing:

Give 1. name: John Doe
Give 2. name: Give 3. name:

It always comes when i hit the spacebar...

**Salem** · 10-31-2001

You mean it looks like this?

Code:

Give 1. name: hello world how
Give 2. name: Give 3. name: Give 4. name: are you today
Give 5. name: Give 6. name: Give 7. name: fine

Names were:
 hello
 world
 how
 are
 you
 today
 fine

Yup, that's exactly what it does...

Ah, got it

Using scanf is tricker in this case.

There are several ways to go, depends what you know already.

Pick one of these which makes most sense. Replace your scanf call with one of these code fragments.

Code:

        for ( j = 0 ; j < 15-1 ; j++ ) {
            name[i][j] = getchar();
            if ( name[i][j] == '\n' ) {
                name[i][j] = '\0';
                break;
            } else {
                name[i][j+1] = '\0';
            }
        }

Code:

        fgets( name[i], 15, stdin );
        name[ strlen(name[i]) - 1 ] = '\0';  /* remove the newline */

Code:

        scanf( "%[^\n]", name[i] );  /* read all chars upto the \n */
        getchar( ); /* remove the \n */
