Add two strings

[Tonave]

Hi everybody!

First i'm sorry for my English because i'm French.

So i would like to add to strings. For exemple, I have : "GPIB0::13::INSTR". 13 is in a char array called ADD.

So I would like to do : "GPIB0::" + ADD + "::INSTR" but I can't!!!!

How can I do this please?

Thanks for your answer!

You can add strings in C in the following way:

    char str [256];

    strcpy (str, "First string " );        // Initialise string to first bit

    strcat (str, "Second string " );       // 'add' second bit

    strcat (str, "Third string" );         // You've probably got the idea by now...

Although I prefer the more general method of constructing strings:

    sprintf (str, "%s %s %s", "First string", "Second string", "Third string" );

because this gives much more flexibility - see the help for sprintf() for a fuller description.

I simply add that in case you prefere there is a french speaking forum community here. You can access it via the "Select community" selector in the upper right corner of the page.
