Thread: help please!!!!!

i am new to c++ and this is my second program for class...keep getting the error, warning: cannot pass objects of non-POD type 'struct std::string' through '...'; call will abort at runtime. can someone help me out please, here is my code:

Code:

#include <stdio.h>
#include <cstdlib>
#include <iostream>

using namespace std; 

// Input first and last name, grade, ande print out their name and lettergrade
int main(int argc , char *argv)

{
	string name, grade, A, B, C, D, F;
	
	cout << "Please insert your first and last name:\n";
	cin >> name;	
	cout << "Please insert your numeric grade:\n";
	cin >> grade;
	name = name;
	grade = grade;
	if ("90" <= grade &&
		grade <="100") A;
	if ("80" <= grade &&
		grade <= "89") B;
	if ("70" <= grade &&
		grade <= "79") C;
	if ("60" <= grade &&
		grade <= "69") D;
	if (grade <= "59") F;
	
	printf("Hello name\n", name);
	printf("You Made grade\n", grade);
}

printf only accepts c-style string, that is const char * typed strings. std::string has a method, c_str that will provide a c-style version of the string.

Code:

printf("Hello name\n", name.c_str());

thanks for the help i fixed it
