	char name[40];
};
struct score
{	int maths;
	int english;

What is the format of your input file?

You can't read a file into anything unless you know what you are reading.

If the input file just consists of these numbers and the string, all seperated by whitespace, can you just declare an object of both your structure types, and read into each of their member variables with the >> operator? Or maybe the problem is more complicated than I thought.

If the string has one word, then you can use the >> operator and just read into some temporary variables:
[code=cpp]
cin >> tempint >> tempfloat >> tempstring;
[/code]

Theh write a funciton that takes these as arguments and returns a pointer to your struct variable. The funciton creates the struct variable on the heap., populates the members and returns the address of the struct variable.

You then write a free() that takes the address of the struct variable and frees memory.
