How to use enums in C? ++How to define static members in C?

C ++It will not return the entire array, but it can return a pointer to the array. Outside the function, the address of a local variable cannot be returned. By making the local variable static, it can return the address of the local variable.

The following is the syntax for returning a pointer.

int　*　function_name()
{ body }

Here,

function_name-User-provided function name.

The following is an example of returning an array from a function.

Example

#include <iostream>
using namespace std;
int　*　ret() {
　　　static int x[3];
　　　for(int i=0 ; i<5　; i++) {
　　　　　　cout << " " << &x[i];
　　　}
　　　return x;
}
int main() {
　　　ret();
　　　return 0;
}

Output result

0x601180 0x601184　0x601188　0x60118c 0x601190

In the above program,ret()Created a function and returned an array. Declare a static int type array and print the address of the allocated memory block.

int　*　ret() {
　　　static int x[3];
　　　for(int i=0 ; i<5　; i++) {
　　　　　　cout << " " << &x[i];
　　　}
　　　return x;
}

inmain()in the function, which functionret()is called-

ret();
