#include <stdio.h> int main ( int argc, char* argv [ ] ) { int value1 = 10; int value2..

Answer / deepak

binary value of 10 = 1010
binary value of 5 = 0101

so if u do bitwise OR. u will get 1111, which is the binary
value of 15. Note: This will not work for all the case:
For eg, value1 = 5 and value2 = 5 will not give u 10.
Instead the printf will print 5 only.

#include <stdio.h> int main ( int argc, char* argv [ ] ) { int value1 = 10; int value2..

Answer / rahul pradhan

In the printf statement, since the expression uses OR (|),
answer is correct.. 10 and 5 will be converted to its
binary equivalent.
10 = 1010
5 = 0101

10 | 5 1010
0101 gives 1111 which is 15....

Also main function takes only two arguments which
are "argc" and "argv".. thus the arguments are
mentioned...even if u just write main() without arguments,
no problem..

#include <stdio.h> int main ( int argc, char* argv [ ] ) { int value1 = 10; int value2..

Answer / sivakumar

the argc and argv are mentioned in the main as arguments
those are used for the purpose of command line statements.
if we mentioned the main like (argc,argb[]),then that
program can work as command line program. like dos
functions(type,copy....).
Then at that time argc contains count of parameters and argv
contains list of arguments.
eg:-
show_sum 10 20 30
then argc contain value 3 and argv containe list{10,20,30).
ok.

argc means argument count
argv means argument vector
argc contains the no of arguments and argv[] contains the
argument values
