Webstruct { size_t length; int * elements; } Another thing you can think about is how strings in C are null terminated instead of storing a length (as in Pascal).

WebC program to find length of a string without using strlen function, recursion. Length of string in C language #include #include int main () { char a [100]; int length; printf("Enter a string to calculate its length\n"); gets( a); length = strlen( a); printf("Length of the string = %d\n", length); return 0; } WebDon't use scanf or gets for that matter because as you say, there is not real way of knowing just how long the input is going to be.
