strpbrk可以理解为找到目标(string)中的字符后中断(break)并返回其地址(pointer),其功能与strcspn相同,区别只是strpbrk返回的是地址。 代码语言:javascript 代码运行次数:0 运行 AI代码解释 复制 #include <stdio.h> #include <string.h> /* 依次检验字符串s1中的字符,当被检验字符在字符串s2中也包含时 则停止检...

The possible signatures are PointerType addressOf(IntType index); The receiver is the pointer that is accessed, i.e., the base address of the memory access. The ValueType must be the Java-equivalent of the C type used in the pointer definition. The optional parameter index (always ...
这是C不会为你做的事情：复制pub fn main() void { var buffer = [_]u8{ 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 }; // Intentionally misalign the pointer so it won't be evenly divisible by 4 var misaligned_ptr = &buffer[3]; var ptr: *u32 = @ptrCast(*u32, @align...
4、 warning: passing argument 1 of ‘send’ makes pointer from integer without a cast 解释:函数send的第一个integer型参数没有强制转换为pointer型 5、warning: comparison is always true due to limited range of data type 解释:由于数据类型范围的限制,比较结果一直为真。
