CODE LOOKS LIKE THIS WAY:

#include<iostream>
using namespace std;
int main(void)
{
float grade,prelim,midterm,prefinal,final;
cout<<“Enter your grades in prelim:”;
cin>>prelim;
cout<<“Enter your grades in midterm:”;
cin>>midterm;
cout<<“Enter your grades in prefinal:”;
cin>>prefinal;
cout<<“Enter your grades in final:”;
cin>>final;
grade=(prelim+midterm+prefinal+final)/4;
cout<<“your grade is:”<<grade<<“\n”;
if(grade>=75 && grade<=100)
cout<<“PASSED\n”;
else if(grade>=50 && grade<=74)
cout<<“FAILED\n”;
else
cout<<“invalid key\n”;

return 0;
}
