size_t in C size_tis an unsigned integral data type which is defined in various header files such as: <stddef.h>, <stdio.h>, <stdlib.h>, <string.h>, <time.h>, <wchar.h> It’s a type which is used to representthe
The sizeof operator can be used to automatically compute the number of elements in an array: Example: size_t in C language #include<stddef.h>#include<stdio.h>staticconstintvalues[]={1,2,4,9,15};#defineARRAYSIZE(x)(sizeofx/sizeofx[0])intmain(intargc,char*argv[]){size_ti;for(...
The real concern is how to declare the function's third parameter, which represents the size of the source object. I suspect many programmers would choose plain int, as in: 真正应该关心的是如何声明函数的第三个形参,也就是代表了源对象大小的的那个形参。我猜很多程序员会选择再简单不过的int类型,...
このチュートリアルでは、size_tコマンドを使用して C で符号なしデータ型変数を定義する方法について説明します。 C 言語のsize_t size_tコマンドは、C 言語で符号なしデータ型変数を定義します。符号なしデータ型は負にできないため、size_tコマンドはintのようなデータ型であり、正の整数...

The size_t argument passed to any function in <string.h> shall have an appropriate value. This rule comes from MISRA C™: 2012 Amendment 1. Rationale The value of a size_t argument passed to a function defined in <string.h> must be positive and not greater than the size of the sma...
