Can you help me understand the output?Thanks

#include typedef struct { int id; double price; char code; } unit; typedef union { int m; int n; double o; } value; int main( ) { unit items [3 ]; for (int i = 0; i price); 2.22 itemPtr->code = 0x61; printf("%2X\\", itemPtr->code); 61 itemPtr->code += 1; itemPtr->code &= ~0x20; printf("%2*\\", itemPtr->code); 42 value valueArray [5 ]; printf("Xd\\", sizeof(valueArray) ); 40 return 0; }
