c++ convert argv[1] to a char array - Electronic Circuits Projects Diagrams Free

is this posible, looking on google turned up nothing.

Code:

main(int argc, char *argv[])
{
 ......
}

Now, the separators for argv are os dependant but typically they are tabs or spaces so

one, two, and three => four strings
one,two, and three => three strings

If you want number parameters you would convert the string into a number using atoi() atof() ...

Can you explain your question a different way?

It is just that argv[1] is already a char array.

What is it that you wish to do?

Can you give us an example of your problem?

Mike.
