Can a variable length array be allocated in C?
Variable length arrays is a feature where we can allocate an auto array (on stack) of variable size. C supports variable sized arrays from C99 standard. For example, the below program compiles and runs fine in C.
How to create a variable length array ( VLA )?
If the value of the constant expression is N, the array has N elements numbered 0 to N-1, Sample declaration of an array with 5 elements of type double should be like: Second, buffer is a variable-length array (VLA). VLAs are partly supported in some compilers as an extension.
Are there variable size arrays in C + + 11?
But C++ standard (till C++11) doesn’t support variable sized arrays. The C++11 standard mentions array size as a constant-expression See (See 8.3.4 on page 179 of N3337).
How to create a buffer with variable length arrays?
Based on the way you use buffer I would suggest using an std::list for it. class Running_Average { private: list buffer; const size_t MaxBufferSize; public: I would also remove the sum, average and i member variables and instead declare them where they are used (if needed).
How are variables created in assembler and memory allocation?
An integer is a whole number with no fractional part. In assembler, the variables are created by data allocation directives. Assembler declaration of integer variable assigns a labelto a memory space allocated for the integer. The variable name becomes a label for the memory space.

How is memory allocated in a variable partition?
In variable Partitioning, space in main memory is allocated strictly according to the need of process, hence there is no case of internal fragmentation. There will be no unused space left in the partition. More number of processes can be accommodated due to absence of internal fragmentation. A process can be loaded until the memory is empty.
