Inside the code:
`#include

// Define get_emergency_number() below:

void get_emergency_number(std::string emergency_number){
std::cout << "Dial " << emergency_number;
}

int main() {

// Original emergency services number
std::string old_emergency_number = “999”;

// For nicer ambulances, faster response times
// and better-looking drivers
std::string new_emergency_number = “0118 999 881 999 119 725 3”;

// Call get_emergency_number() below with
// the number you want!
get_emergency_number(new_emergency_number);

}`

How come if I put in ‘string emergency_number’ instead of ‘std::string emergency_number’ for the parameter in the ‘void get_emergency_number’ function I get an error?
