Code being skipped

[Bill]

Hi,
My program is skipping over the prompt to enter a first name on the
second pass thru. Any help would be appreciated:

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


#define first_name_len 30
#define last_name_len 50


void strip_newline( char *str, int size )
{
int i;


/* remove the null terminator */
for ( i = 0; i < size; ++i )
{
if ( str == '\n' )
{
str = '\0';


/* we're done, so just exit the function by returning */
return;
}
}
/* if we get all the way to here, there must not have been a
newline! */



}


int main()
{
char name[50];
char lastname[50];
char fullname[100]; /* Big enough to hold both name and lastname */

char cmd;

do{
printf( "Please enter your name: " );
fgets( name, 50, stdin );


/* see definition above */
strip_newline( name, 50 );


/* strcmp returns zero when the two strings are equal */
if ( strcmp ( name, "Bill" ) == 0 )
{
printf( "That's a cool name.\n" );
}
else
{
printf( "That's not my name.\n" );
}
// Find the length of your name
printf( "Your name is %d letters long", strlen ( name ) );
printf("\n");
printf( "Enter your last name: " );
fgets( lastname, 50, stdin );
strip_newline( lastname, 50 );
fullname[0] = '\0';
/* strcat will look for the \0 and add the second string starting
at
that location */
strcat( fullname, name ); /* Copy name into full name */
strcat( fullname, " " ); /* Separate the names by a space */
strcat( fullname, lastname ); /* Copy lastname onto the end of
fullname */
printf( "Your full name is %s\n\n",fullname );


printf("Enter c to continue, or q to quit");


cmd = getchar();
name[0] = '\0';
lastname[0] = '\0';
fullname[0] = '\0';


}while(cmd == 'c');


return 0;

[...]
do{ [...]
printf("Enter c to continue, or q to quit");


cmd = getchar();
name[0] = '\0';
lastname[0] = '\0';
fullname[0] = '\0';


}while(cmd == 'c');

What do you type, key for key, when you wish to continue?

In the future, if you want to post the same message

to each group, cross-post instead. Thank you.

c and ENTER, which goes into the first name variable. I tried fgets,
but then the program just executes once and quits.

I hoped that your answer would be enough for you to figure it out
yourself. getchar() reads a single character. You enter two characters.
The second character remains unread as you restart the loop.

Call getchar twice. The first time will get the 'c', the second time
will get the '\n' (ENTER).

Works like a champ! Thanks!
