Question

Is there any way to construct an array of strings inside a function call? For example, say I have a function like this:

void foo( char * [] strings )
{
    //...does stuff
}

And instead of declaring the character array first and then passing it, is there any way, with arrays or any other container class, to call the function like this?

foo( { "a", "b", "c", ...} );

Basically I have a function that prompts a user for input until it matches one of the strings in the array I pass, and since that changes throughout the program, I pass the accepted inputs into the function that prompts the user and validates the input. Currently I am just constructing it outside the function and passing it in but was wondering if they could be combined into one line in any way

Answer 1

This works in C99:

void fun(char *argv[])
{
    while(*argv)
        printf("%s\n", *argv++);
}

fun((char*[]){"aaa", "bbb", NULL});

Since you mention “container” you probably use C++ so this answer is of limited value (unless you are using a compiler that accepts it as an extension – the way GCC does for example).
