one question about string

[omryk]

I want to write function that take array of strings and return to me one string that contain all of the words i passed to this function
i have problem with how to pass to function (prototype)

here is the main :

void main()
{
char *words[]={{"a"},{"picture"},{"is"},{"worth"},{"a"},{"thous and"},{"words"}};


char *word=sentence(words);
puts(word);

}

and the prototpye of sentence function is like this

char *sentence(char ** words);

is it ok? or wrong and how can i get the first word
is it *words[i] ?
best regards

You CANNOT make a function return a string or or any array. What you can do is pass a one dimensional array of charachters as another parameter to the function and alter it inside this function, and make the return type void( void sentence(char ** words,char *word) ). But there isn't anything else wrong.

1. Function sentence has no way of inferring the dimension of the passed array. That's why, for instance, the standard prototype for main has the argc argument.

2. You're declaring variable word with an initializer, but the value of the initializer isn't known until run-time. Don't know about C++, but you can't do that in C. Separate the declaration from the assignment.

3. Realize that if you declare word as a char* then it will only be a pointer. That leaves it up to somebody else (sentence?) to allocate the memory needed to hold the concatenation of all the strings in the words array.

tnx but is it the same solution as u offered in C and C++ or maybe in C++ i can do something else?
