displaying number of students in each course

[young1]

I'm using c++(language)
i need to display number of students doing each course, seemingly it displays the first number well but the second time i try it adds all the students doing all courses. here's the code below:

    {
                    string str;
                    int n, count = 0;
 
                cout<<"Enter number of courses: ";
                cin>>n;
 
            for(int i=0; i<=n-1; i++)
                    {
                    cout<<"Enter course: ";
                cin>>str;
 
         for(int i=0; i<=str.size(); i++)    
 
         {         
 
         if(str == stud[i].cours)
 
         {
 
count++;
 
cout<<"Number of students doing "<<str<<" are "<<count<<endl;
 
}
 
}
 
 
}
 
}

From the snippet you have provided, it seems that a single count variable is being used. Different count variable needs to be used for each course to display distinct results.

Also, only the count++ part should be present in the body of if. After the if block, count can be printed.
