Question

Point out the errors, if any, in the following C statements:
(a) int = 314.562 * 150 ;
(b) name = ‘Ajay’ ;
(c) varchar = ‘3’ ;
(d) 3.14 * r * r * h = vol_of_cyl ;
(e) k = ( a * b ) ( c + ( 2.5a + b ) ( d + e ) ;
(f) m_inst = rate of interest * amount in rs ;

Answer 1

I've only programmed in C++ but the answers should be the same
(a) int = 314.562 * 150 ; int is a reserved word, you can't assign it a value. and if it does allow you to do that, then your assigning a double value to an int variable.
(b) name = ‘Ajay’ ; if name is a string, you need " Ajay "
(c) varchar = ‘3’ ; this should be okay. not sure
(d) 3.14 * r * r * h = vol_of_cyl ; this is backwards. vol_of_cyl should be in front of the =
(e) k = ( a * b ) ( c + ( 2.5a + b ) ( d + e ) ; your missing a parenthesis
(f) m_inst = rate of interest * amount in rs ; rate of interest and amount in rs have spaces. can't have spaces in variable / function names

Answer 2

Thanks Its correct ! I knew the answer i just wanted to b sure so now i am sure !

Answer 3

kk, no problem :)

Answer 4

just an addition...e is wrong coz there are no operators between the parenthesis not because of missing par...

Answer 5

ok missing para...... too

Answer 6

doesn't it automatically multiply it? because of parenthesis i mean.

Answer 7

Answer 8

Answer 9

(c) varchar is also a data type:
