Need of Buffer Memory in C

The need for buffer memory is very case-specific. Take the above example for user input in the C console application. Assume that you have to store a multi-digit number in a variable so you will have to enter them digit by digit. If there is no buffer memory, the first digit you enter will directly be stored inside the variable and you won’t be able to store the rest of the digits.

So basically,

Buffer Memory is required to synchronize the data tranfer by temporarily storing it till it is ready to be transferred or processed.

Moreover, they reduce the I/O calls for read and write operations.

In C, the buffer is referred to as a sequential section of memory that is used to temporarily store some data that is being transferred from one place to another. For Example, in C language, the data entered using the keyboard is first stored in the input buffer, and then it is stored in the memory.

In this article, we will discuss what is a buffer memory, its uses, and limitations in C.
