Integers are whole numbers which will be stored in computer using 4 bytes (32 bit) of memory. Example: 65 Binary equivalent of 65 is (1000001) . The MSB (most significant bit) bit is used to indicate whether the number is positive or negative. For positive numbers MSB will be 0. For…

What is a library? Library in C is a collection of header files, exposed for use by other programs. The library therefore consists of an interface expressed in a .h file (named the "header") and an implementation expressed in a .c file.
