any idea how on earth i make this more efficient?
Code: Select all
char names[5][25];
double grade1[4];
double grade2[4];
double grade3[4];
double grade4[4];
double grade5[4];
for(int i=0;i<5;i++)
{
cout << "Please enter the name of student " << i+1 << ":";
cin >> names[i];
cout << endl;
}
for (int k=0;k<5;k++)
{
cout << " Please enter " << names[i] << " grades.";
for (int o=0;o<4;o++)
{
cout << "Please enter grade " << o+1 << ":";
if (k==0)
{
cin >> grade1[o];
}
if (k==1)
{
cin >> grade2[o];
}
if (k==2)
{
cin >> grade3[o];
}
if (k==3)
{
cin >> grade4[o];
}
if (k==4)
{
cin >> grade5[o];
}
}
}

Code: Select all
#define STUDENTS 5
#define GRADES 4
char names[STUDENTS][25];
double grades[STUDENTS][GRADES];
for(int i=0;i<STUDENTS;i++)
{
cout << "Please enter the name of student " << i+1 << ":";
cin >> names[i];
cout << endl;
}
for (int k=0;k<STUDENTS;k++)
{
cout << " Please enter " << names[k] << " grades.";
for (int o=0;o<GRADES;o++)
{
cout << "Please enter grade " << o+1 << ":";
cin >> grades[k][o];
}
}

If you ask the grades in the same loop as you ask the names, you can save a bit of looping time too
But i don't know if you want to change to the flow

Might consider creating a vector of a struct of something like this:
Code: Select all
struct StudentGrades{
char *studentName;
vector<int> grades;
};
vector<StudentGrades> students;
Then you can interact with the variable 'students' for all your needs. (Allowing nearly unlimited records)
