{char *s=“Hello,world”;printf(“%10s”,s);}
a) Hello,world0000000000 b) Hello,worl c) 0000000000Hello,world d) Hello,world
ans: d
2. In the below program the getNewString function is defined and it returns a character pointer. This function is called from main function as defined below. What will be the output of this program?
char *getNewString( )
{static char xxx[1024];return xxx;}
main( )
{char g[]=“First”;char *p;strcpy(getNewString( ),g);
p=getNewString( );
strcpy(p,“Second”);
printf(“The string is : %s”,getNewString( ));}
a) The string is : First b) The string is : FirstSecond c) The string is
ans: c

: Second
d) Unknown, since the scope of the pointer is local
