If the size of the array is indicated by * instead of an expression, the variable length array is considered to be of unspecified size. Such arrays are considered complete types, but can only be used in declarations of function prototype scope. A variable length array and a pointer to a ...

I didn’t try to implement a similar function that doesn’t use a variable-sized array, but it would be easy to allocate a chunk of memory in the function and produce the same output. So the VLA is possible, but not absolutely necessary. From the Wikipedia page on variable length array...
The C99 (ISO/IEC 9899:1999) standard of C introduced a new, powerful feature called Variable Length Arrays (VLAs). The size of an array with automatic storage duration (i.e. stack allocated) can be determined at run time. Each instance of the array may even have a different length. Unl...
When a variable length array (C99 supported) is declared, and error: "expression must have a constant value" is raised. To Reproduce #include<stdio.h>intmain(void) {inti,n;printf("How many numbers do you want to reverse? ");scanf("%d",&n);inta[n];printf("Enter &d numbers: ",n...
The following example demonstrates how to use C99 Variable Length Arrays (VLAs) in a firstprivate directive (Section 2.7.2.2 on page 26).备注 Variable length arrays are not currently supported in Visual C++.复制 void f(int m, int C[m][m]) { double v1[m]; ... #pragma omp parallel...
Let arrays still have fixed sizes - no suprises. If one > wants variable sized arrays, be aware that they are allocated on the > stack only... You think this is possible/plausible?[/color] If they do anything, I suspect it will be the same as C99. Brian...
This dictionary is a bit like an array, it is an indexed collection, this time not by integers like arrays, but by keywords. To those keywords are associated values accessible via the message at:, such as in: Smalltalk at: #Smalltalk In the Smalltalk global dictionary, the keys are the ...
