Given an char variable last that has been initialized to a lowercase letter, write a loop that displays all possible combinations of two letters in the range ‘a’ through last.
LANGUAGE: C++
CHALLENGE:
Given an char variable last that has been initialized to a lowercase letter, write a loop that displays all possible combinations of two letters in the range ‘a’ through last. The combinations should be displayed in ascending alphabetical order:
For example, if last was initialized to ‘c’ the output should be aa
ab
ac
ba
bb
bc
ca
cb
cc
SOLUTION:
for (char outterChar='a'; outterChar <=last; outterChar++){ for (char innerChar='a'; innerChar <=last; innerChar++){ cout << outterChar << innerChar << "\n"; } }
