| Given an array of characters which form a sentence of

the words (not characters) in it.
| Microsoft | 7 |
| main()

{
case 1: printf("1");
case 2: printf("2");
default : printf("0");
}
} | | 1 |
| main()
{
char *p="hai friends",*p1;

while(*p!='\0') ++*p++;
printf("%s %s",p,p1);
} | | 1 |
| #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;
printf("%d %d ",sizeof(*p),sizeof(p));
} | | 1 |
| 1)
int i=5;
j=i++ + i++ + i++;
printf("%d",j);This code gives the answer 15.But if we
replace the value of the j then anser is different?why?
2)int i=5;
printf("%d",i++ + i++ + i++);
this givs 18. | Infosys | 6 |
