| You are given any character string. Find the number of sets
of vowels that come in the order of aeiou in the given
string. For eg., let the given string be DIPLOMATIC. The
answer returned must be "The number of sets is 2" and "The
sets are "IO and AI". Vowels that form a singleton set must
be neglected. Try to post the program executable in gcc or
g++ or in java. | | 3 |

| #include"math.h"
void main()
{
printf("Hi everybody");
}
if <stdio.h> will be included then this program will must
compile, but as we know that when we include a header file
in "" then any system defined function find its defination
from all the directrives. So is this code of segment will
compile? If no then why? | | 2 |
| main()
{
char *p="GOOD";
char a[ ]="GOOD";
printf("\n sizeof(p) = %d, sizeof(*p) = %d, strlen(p) = %d",
sizeof(p), sizeof(*p), strlen(p));
printf("\n sizeof(a) = %d, strlen(a) = %d",
sizeof(a), strlen(a));
