Answer 1

age[ 0 ] will be an undefined value until you write into it, which is why initializing "min" with it is undefined behaviour and will likely lead to wrong results. Choosing a sufficiently large constant instead should be enough, e.g. the max value an int can store:

int min = ( ( 1u << 31 ) - 1 );

You could also request the first value seperately beforehand and use that to initialize "min", then run the loop only for the remaining four elements.
