3.3 Numeric data typesFrom the moment we open our eyes every morning, we deal with numbers almost every hour: from 6:30 on the alarm clock to the 216 bus to work, from the news that the house price fell to 100 yuan per square meter to go home to buy

I. Basic points of knowledge1. Keywords, identifiersThe C language provides 34 keywords, and identifiers are the names of functions and variables.2. Data typeUnderstanding the type of data helps to understand how data is stored, so Korean is

In actual software development projects, there is often a need to implement the deletion of outdated files. This requires that the program be able to automatically delete files that were generated before the time. This article provides a sample code

One byte has 8 bits, so the 32-bit int occupies 32-bit/8-bit = 4-byte, and 64-bit int uses 64-bit/8-bit = 8 bytes. 32-bit, 64-bit unsigned integer maximum value: 2^64-1 = 18446744073709551615 2^32-1 = 4294967295 32-bit, 64-bit signed integer
