Arrays as function parameters in C

#include <stdio.h> #include <stdlib.h> void printSize(int* arrParam) { printf("Size of the array in function %llu\n", sizeof(arrParam)); arrParam[2] = 10; } int main(int argc, char* argv[]) { int arr[5] = { 1, 2, 3, 4, 5 }; printf("Size of the array in main %llu\n", sizeof(arr)); printSize(arr); // arr -> int* printf("%d\n", arr[2]); return 0; }
