First Fit Algorithm C Program

By | November 4, 2016
 

Let us learn how to implement First Fit Algorithm in C programming language. The memory management program for First Fit Algorithm uses Arrays.

What is First Fit Algorithm?

The First Fit Memory Allocation Algorithm allocates the first free partition available in the memory that is sufficient enough to hold the process within the system.

It does not check for the minimum required space but whichever partition is encountered first that can handle the process is selected.

Advantage

This is a very fast searching algorithm since it does not have to search a lot.

Disadvantage

However, the disadvantage with this memory management algorithm is that the extra space cannot be used by any other process.

Note: This C Program for First Fit Memory Management Algorithm in operating system is compiled with GNU GCC compiler and written in gEdit Editor in Linux Ubuntu operating system.

    There is an advanced version of the first fit algorithm, known as Modified First Fit Algorithm.

    suppose.. if the process is not allocated..then what will be values of..fragments[m]=temp and blockarr[filearr[m]] =1…what ll happen to these statements…

    the program is allocating the 2nd block to the 2nd process if the first process size exceedes the size of the 1st block, it should allocate the 2nd process to the block 1 if the process 1 is not allocated….Pls verify
