if(l>10)
break;
}
}
(a) The condition in the for loop is a must (b) The two semicolons should be dropped

{
char *p=destination;
while(*source!='\0')
{

}
char *f()
{
char result[80];
strcpy(result,"anything will do");
return (result);

}
(a) infinite number of times (b) 32767 times
(c) 65535 times (d) till the stack does not overflow
19.Notice the error in the default statement in the code snippet below.Will it give a compilation error?

break;
case 50: printf("the value is 50");
break;
default:printf("the value is not 30 or 50");
}
}
fn(int a)
{
return (++a);
}
(a) Will display "the value is 30" (b) Will display "The value is not 30 or 50"
(c) Yes a compilation error would happen
(d) No compilation errors but there will be no output on the screen
20.What would be the output of the following program.
