What is the storage format of the symbol integer 98 in memory in C language

Add 1, get the supplementary code of -10: [11111111111011 0] It can be seen that the first one on the left represents the symbol.

nt type is a signed integer type. For a 16-bit compiler, int occupies 2 bytes and 8 bits;For 32-bit and 64-bit compilers, the int type occupies 4 bytes and 32 bits.

In C language, integer data types are used to store integers, including the following types: char: used to store characters, generally occupy 1 byte, and can store integer values of ASCII code characters. Short: used to store short integers, generally occupying 2 bytes, ranging from -32768 to 32767.

The first one, whether it is 98 or 'b', the storage form in memory is 98 saved in binary. If you use or c language printf, you will know that it is a formatted output statement, that is, how to output the data in memory, (int) is Format output of shaping.

What does the large and small order mean

There are four main statements: the first one is that the preface of "Guan Yong" is the longest, collectively known as the "Great Preface of Poetry". Except for "Guan Yong", the prefaces before the other articles are called "small preface".

The table of contents is the table of contents contained in front of the body of the book. It is a tool for revealing and reporting books. The catalog is to record the title, author, publication and collection of the book. It is arranged in a certain order. It is a tool to reflect the library, guide reading and retrieve books.

How to confirm whether the system adopts large-end or small-end**

1. Large-end large-end (storage) Mode: ** means that the content of a data in low byte order is placed at the high address, and the content stored in high byte order is placed at the low address.

2. The so-called big endIt refers to the low-bit address of the high-bit value in memory, and the so-called small-end refers to the low-bit address in the memory of the low-bit value. For example, 0x11223344 is 11223344 on the large terminal and 44332211 on the small terminal, and whether a machine is a large-end or small-end depends on the CPU type and the operating system running on it.

3. The following program can judge whether a machine is large-end storage or small-end storage.

4. It's not the same concept. Large-end mode: high bytes are put into low addresses. Small-end mode: high bytes are put into high addresses. Generally, it should be separated in the single-chip microcomputer system. The commonly used X8GCC-AVR is the small-end mode; while the KEIL C51 is the large-end mode. There are also other compilation environments with default modes, depending on the description of the variable environment.

5. Some processor systems use small-end methods to store data, such as Intel's Pentium. Some processor systems use large-end data storage, such as IBM Semiconductor and Freescale's PowerPC processors. Not only for the processor, but also for the design of some peripherals, there is also a choice to use a large end or a small end for data storage.
