• Name: read_header_information()
• Input: an ifstream object to read from, integers corresponding to the width height & max value in the image passed by reference
• Output: true if valid type, false otherwise
• Description: Reads the header block of the file (the first four values). Returns true if the PPM type is P3, false otherwise. Upon completion, the parameters corresponding to the width, height, & maximum value will correspond to the values read from the image.

Can you explain this? I am writing a C++ program, and this is a function I am supposed to create. The pseudocode is confusing me. Can you please help!
