If you have a function that takes a const char * pointer, and you have a char array or char pointer, it is valid C/C++ to pass the pointer without cast. An array can be passed to functions in C using pointers by passing reference to the base address of the array, and similarly, a multidimensional array can also be passed to functions in C. Array can be returned from functions using pointers by sending the base address of an array or by creating user-defined data type, and this pointer can be used to access elements stored in the array. e1m1 April 28, 2023, 10:54am 1.

If you want to pass a single-dimension array as an argument in a function, you would have to declare a formal parameter in one of following three ways and all three declaration methods produce similar results because each tells the compiler that an integer pointer is going to be received. By the end of the thirteenth century both in France and England, this sound /ts/ de-affricated to /s/; and from that time c has represented /s/ before front vowels either for etymological reasons, as in lance, cent, or to avoid the ambiguity due to the "etymological" use of s for /z/, as in ace, mice, once, pence, defence. Yet for these new sounds c was still used before the letters e and i. The digraph ck is often used to represent the sound /k/ after short vowels, like "wicket".
