Running a linux command in C++ program -


i trying run following in c++ program:

string cmd("strings -n 3 < binaryfile > ascii.txt"); system(cmd.c_str();

binaryfile string contains /home/test/binaryfile

when run so, following output:

sh: binaryfile: no such file or directory

if try following:

string cmd("strings -n 3 < binaryfile.c_str() > ascii.txt"); system(cmd.c_str();

i these errors:

sh -c: line 0: syntax error near unexpected token '(' sh -c: line 0: 'strings -n 3 < binaryfile.c_str() > ascii.txt

how can run properly?

you need construct command line explicitly: 

string cmd("strings -n 3 < " + binaryfile + " > ascii.txt"); system(cmd.c_str());

'hasOwnProperty' in javascript -

i use obj.hasownproperty judge whether object has property, when replaced obj[prop] !== undefined , not normal implementation, ask, why behind method can not use it? object.hasownproperty(prop); object[prop] !== undefined; obj[prop] !== undefined wrong 2 reasons: you can explicitly set property undefined , obj[prop] = undefined; . obj.hasownproperty(prop) return true in case. obj[prop] follow prototype chain, return property that's inherited. obj.hasownproperty(prop) returns true if property exists directly in object, returns false inherited properties.
