for (unsigned int i = 0; i != histogram.size(); ++i) 最省力的,将i改成unsigned int 就不会产生这个警告了 for (std::size_t i = 0; i != histogram.size(); i++) size_t 类型定义在cstddef.h中,该文件是C标准库的头文件stddef.h的C++版。它是一个与机器相关的unsigned类型,其大小足以保...
1、问题 jni编译报错comparsion between signed and unsigned integer expressions 2、原因 在for循环里面,不能用无符号32整形数据作为判断条件 2、解决办法 先把无符号32整形数据强转为整型数据,然后再去作为条件
这是个一般性质的警告, 只是提示你代码中存在 有符号和无符号的整型数据进行逻辑运算.这种警告是完全可以无视的, 因为编译器会自动处理的.

object is moving backwards and you find the integer in memory representing that object's movment and invert the bits, it will change directions. You can interpret this as a signed int, just because behavior wouldn't really reflect the same way if the function were designed to use unsigned ...

if the operand that has unsigned integer type has rank greater or equal to the rank of the type of the other operand, then the operand with signed integer type is converted to the type of the operand with unsigned integer type. unsigned int and int has the same rank, so it's equivalent...

What is an signed and unsigned integer number? I know that an unsigned integer number holds zero and positive numbers; signed, vis versa but including negative numbers. Why would you want to use these statements in a c++ program? how do they work in a c++ program -- what is their functi...
