Answer 1

what is your input ?

Answer 2

All possible cards for Straight bro

Answer 3

i.e. this is ok becuase input is sorted
7C 6S 5S 4H 3H

but this no
7C 6S 5S 3H 4H

because in unsorted input
3 - 5 is not 1 and
5 - 3 is not 1

for (int o=1;o<5;o++){
if (v4[o] - v4[o-1] == 1) {
e++;
} else
if (v4[o-1] - v4[o] ==1) {
r++;

Answer 4

Oh,I see
Many thanks for your help
