Answer 1

Program:

#include <iostream>
#include <string>
using namespace std;
string STUDENT = "ckim84"; // Add your Blackboard login name
extern string ASSIGNMENT;

/**
* Describe the purpose of your program here.
* @return 0 for success.
*/
/* int run()
{
return 0;
} */ // Here no need to write run method

string repeatChar(int n, const string& pat)
{
string result;
for (int i = 0; i < n; i++)
{
result += pat;
}
return result;
}
int main() {
repeatChar(3, "abcde$");
   return 0;
}

Output: Executed successfully
