Okey i'm lost with this question ---- c++ program can u please help me!?

the question says:


Develop a program that asks for a students name and final grade (in numberical form) and prints out the students name, letter grade, and GPA.





e.g. Please enter students name: Kieran Ryan


Please enter Kieran Ryan's grade: 100


Kieran Ryan got an A in your class and has a GPA of 4.0!!!





Use the following to calculate the Letter Grade and GPA:


Percent GPA Letter Grade


90-100 4.0 A


85-98 3.5 B+


80-84 3.0 B


75-79 2.5 C+


70-74 2.0 C


60-69 1.0 D


0-59 0.0 F





I'm stuck at:


#include %26lt;stdio.h%26gt;


#include %26lt;iostream%26gt;


#include %26lt;string%26gt;


using namespace std;





int main ()


{


string mystr;


cout %26lt;%26lt; "What's your name? ";


getline (cin, mystr);


cout %26lt;%26lt; "nice name " %26lt;%26lt; mystr %26lt;%26lt;"\n";


cout %26lt;%26lt; "What is your grade? ";


getline (cin, mystr);


if= mystr





90-100 4.0 A


85-98 3.5 B+


80-84 3.0 B


75-79 2.5 C+


70-74 2.0 C


60-69 1.0 D


0-59 0.0 F


cout %26lt;%26lt; "the student got" %26lt;%26lt; mystr %26lt;%26lt; " which is an A\n";


system("pause");


return 0;


}
