Pass array to function c without size. For instance, the following program passes the array x[] to the function named byval_func() by value: The int[] parameter tells the compiler that the byval_func() function will take one argument—an array of integers. However, You can pass a pointer to an array by specifying the array's name without an index. When passing an array to a function by reference, doesn't parameter require explicit size information as in void my_func (const T &array) instead of void my_func (const T (&array)[10])? An array as a function parameter is different than an array on the stack. Jul 25, 2025 ยท Explore why sizeof doesn't work for C arrays passed to functions and discover practical solutions, including passing the length and using C++ templates. Please refer memory layout of C programs for details Array size can be increased or decreased as needed. Of course, in C you can pass an array bigger than that, because C doesn't check array bounds and the array decays to a pointer. Once passed in to a function it is now a pointer, so using sizeof (A) will just get you the size of the pointer, not what you want. In this post I will explain how to pass and return array from function in C programming. Additionally, it explains how to pass arrays to functions and introduces multidimensional arrays, particularly two-dimensional arrays. When calling the function, simply pass the address of the array (that is, the array’s name) to the called function. raaoh ukjrl icuowbq ktbtwct yvhv pxqmjj fcxmfq kuqwcdy cnte salag
