in the tutorials they dont really work...
Code:
#include <stdio.h> /* stdin, printf, and fgets */
#include <string.h> /* for all the new-fangled string functions */
/* this function is designed to remove the newline from the end of a string
entered using fgets. Note that since we make this into its own function, we
could easily choose a better technique for removing the newline. Aren't
functions great? */
void strip_newline( char *str, int size )
{
int i;
/* remove the null terminator */
for ( i = 0; i < size; ++i )
{
if ( str[i] == '\n' )
{
str[i] = '\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 */
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, "Alex" ) == 0 )
{
printf( "That's my name too.\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( "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",fullname );
getchar();
return 0;
}
When i compile. it compiles fine but when i run, nothing happens, any ideas how to fix it?
