c++ - Why I cannot do 'cout << 3*" ";'? -


why cannot 

cout << 3*" ";

error:

e:\c++\test\main.cpp|12|error: invalid operands of types 'int.' , 'const char [2]' binary 'operator*'

some languages allow multiplication operator used in way. instance python allows write:

3*" "

and evaluates as

"   "

but c++ not allow use of multiplication operator. precisely compilation error telling you.

you attempting create string contains 3 spaces. this, example, using fill constructor of standard string class:

std::string(3, ' ')

and send cout:

std::cout << std::string(3, ' ');
