Nettet15. jan. 2013 · sizeof (int [3]) is the size, in bytes, of an array of three integers. sizeof isn't an actual function that gets called while your program is running - it is resolved at … NettetAnswer. 200 bytes. Reason — The size of int data type is 4 bytes. Since B is an array of int type, the size of each element of the array will be 4 bytes. The array has 10 rows and 5 columns, thus total number of elements will be 10 X 5 = 50. The size of 50 elements will be 50 X 4 = 200 bytes. Answered By.
Nettetsizeof is a unary operator in the programming languages C and C++. It generates the storage size of an expression or a data type, measured in the number of char -sized units. Consequently, the construct sizeof (char) is guaranteed to be 1. Nettet2. apr. 2024 · buffer = calloc (100, sizeof (int) ); En este ejemplo se utiliza el operador sizeof para pasar el tamaño de un int, que varía según el equipo, como un argumento de una función en tiempo de ejecución denominada calloc.

Many programs must know the storage size of a particular datatype. Though for any given implementation of C or C++ the size of a particular datatype is constant, the sizes of even primitive types in C and C++ may be defined differently for different platforms of implementation. For example, runtime allocation of array space may use the following code, in which the sizeof operator is applied to the cast of the type int:
