/* Armstrong Numbers An Armstrong number is a number that is the sum of its own digits each raised to the power of the number of digits. For instance, a 3 digit number will be considered an Armstrong number if the sum of the cubes of its digits is equal to the number itself. For example, 153 is an Armstrong number, as 1**3 + 5**3 + 3**3 = 153 Create a program to print all Armstrong numbers in a given range. -----------------Important--------------------- Enter the word range if you want a range then enter the lower and the upper bound separated by a space. example: range 1 20 If you just want to check for a number znter any word and input your number. example: no 12 ----------------------------------------------- */ #include #include #include using namespace std; bool strong(int x){ int sum(0); for(char c:to_string(x)){ sum+=(c-'0')*(c-'0')*(c-'0'); } return sum==x; }//Armstrong function int main() { string dec;//decision range or not cin>>dec; for(int i(0);i!=dec.size();i++){ dec[i]=tolower(dec[i]); }//put range to lowercase so it is type insensitive if(dec=="range"){ int n,m; cin>>n>>m;//n=lower bound, m=upper bound string res; for(int l(n);l!=m+1;l++){ if(strong(l)){ res+=","; res+=to_string(l);//if l is an armstrong number it is added to res as a string } } res[0]=' '; //first character of res is "," and we don't want that cout<<"The Armstrong numbers between "<>h; cout<
