Explanation / Answer

#include <iostream>

using namespace std;
void rev(string s){
for(int i=s.length()-1;i>=0;i--){
cout<<s[i];
}
cout<<endl;
}
void printX(int n) {
for(int i=0;i<n;i++) {
cout<<n;
}
cout<<endl;
}
void exer4(string s, int n) {
for(int i=0;i<n;i++) {
cout<<s<<n;
}
cout<<endl;
}
int main()
{
rev("hello");
printX(5);
exer4("d", 5) ;
return 0;
