How to append a char to a std::string?

Question

The following fails with the error prog.cpp:5:13: error: invalid conversion from ‘char’ to ‘const char*’

int main()
{
  char d = \'d\';
  std::s         


        

Answer 1

str.append(10u,'d'); //appends character d 10 times

Notice I have written 10u and not 10 for the number of times I'd like to append the character; replace 10 with whatever number.
