From numbers in vector program shall output min value without repeating elements.

Answer 1

The issue was caused by an incorrect initialization as well as condition in the last for loop. This fixed version should be working:

You can shorten your function by making use of the STL, which predefines algorithms for sorting and removing consecutive duplicate values:

Eashan Morajkar Not sure what your source for that statement is, but both C and C++ have a `long long` integral type modifier (as of C99 and C++11, respectively). The type is not an issue here. See:

Answer 2

You cannot return a unsigned long long because such type doesn't exist, the unsigned can hold 4 bytes of positive numbers which can contain 4,294,967,296, adding a long after unsigned doesn't make it increase its size, to store more values that unsigned you will need to use two variables or more
