printf("%d",(printf("Hello"));


Result is Hello5 
Inner printf prints Hello and outer printf gives length of
string i.e. 5

error will occur because within a printf statement another 
printf statement is present

prinf execution starts from right to left so it will prints
hello &here printf is taken as a function, it returns int
value as len of srting is 5.it does'nt count /0

Result is Hello5 
Inner printf prints Hello and outer printf gives length of
string i.e. 5

5 , Hello

if the statement is as shown above then it will show an
error due to incomplete parentheses(there are 3 opening and
2 closing)

once that is corrected then you will get the output as
hello5 for the reasons explained above.

it will show hello5
hello from the inner printf and 5 value return by the outer 
printf function,as printf return int value of the string
and in the example there is 5 wrds so the lenght is 5 which 
it return.

the printf fun() always writterns the numbeer of characters
...... so 5 is o/p

error bcz 1 bracket is missing.
if corected
output will b

Hello5

printf function returns the number of character it prints
so output:Hello5

It returns Hello5.since the inner printf been called
first,it would return the number of characters printed
successfully.so the result is Hello5

It will print hello with length of 5.Because return value of
printf is length of that string.

an Error will occur....bcos the function call is missing in 
main().

hello5
