Consider the following program where the zu format specifier is used to display as an integer the result of sizeof. #include #include typedef union { int *i1; int *i2; }U; int main() { U temp; int i = 50; temp. i1 = &i; printf("%zu and %d\n", sizeof(temp), *(temp. i2)); return 0; } What is the output of the program above? Note in the choices below indicates output that isn't any of the literal values in the code above.
