The sizeof keyword gives the amount of storage, in bytes, associated with a variable or a type (including aggregate types). This keyword returns a value of type size_t. 其返回值类型为size_t,在头文件stddef.h中定义。这是一个依赖于编译系统的值,一般定义为 typedef unsigned int size_t; 世上...
cout<<sizeof i<<endl; // sizeof object的用法,合理 cout<<sizeof 2<<endl; // 2被解析成int类型的object, sizeof object的用法,合理 cout<<sizeof(2)<<endl; // 2被解析成int类型的object, sizeof(object)的用法,合理 cout<<sizeof(int)<<endl;// sizeof(typename)的用法,合理 cout<<sizeof...
img.data= <memoryat0x000002D0F2D026C0> 3、dtype属性 dtype属性描述的是numpy数组中数据类型,可以通过astype进行转换后看到dtype的变化,以及因为dtype变化引起itemsize相关属性的变化。 下面这个例子读出opencv-logo.png图像后再转换为np.uint32和np.float64: importnumpyasnp importcv2 print('VX公众号: 桔子cod...
1.Python rstrip() 删除string 字符串末尾的指定字符(默认为空格). (1)sizeof sizeof(...)是运算符,在头文件中typedef为unsigned int,其值在编译时即计算好了,参数可以是数组、指针、类型、对象、函数等。 它的功能是:获得保证能容纳实现所 python中size函数的用法 Python 字符串 数组 python 转载 数码悟...
