Find the two highest elements in an unsorted array

2 Answers

int* two_Largest(int* arr) { int* myArr = new int [2]; myArr[0] = INT_MIN, myArr[1] = INT_MIN; int len = sizeof(arr)/sizeof(int); for(int i =0; iarr[0]) { myArr[1] = myArr[0]; myArr[0] = arr[i]; } else { myArr[1] = arr[i]; } } }

Not sure what language this is suppose to be, but: 1) sizeof(arr), which arr is a pointer, is not going to be the size of the in bytes 2) you have the function returning an int *, but there is no return statement, so you are returning garbage 3) why are you comparing arr[i] to arr[0] every time?!? This is a really bad answer.

1) Swap MSB with LSB of 16bit No 2) related to CV 3) integer Overflow 4) bits logic 5) storage classes, volatile etc Don't remember exactly. But most of them from C, data types, bits, embedded.
