Argv[] to Hex

[johns420]

I am trying to figure out how to take in argv as a hex value.

An example would be - ./myprogam abcdef123456

I need the value of abcdef123456 to be a hex value of 0xabcdef123456

I have tried google and various attempts (scanf, strtol, atoi) and can't seem to get it working. Any help would be amazing.

Use stringstreams and manipulators
