Return array from functions in C + +

C + + does not allow to return an entire array as an argument to a function. However, you can return a pointer to an array by specifying the array ' s name without an index.

If you want to return a single-dimension array from a function, you would has to declare a function returning a pointer a s in the following example:

int* myFunction(){

.

.

.

}

Second point to remember are that C + + does not advocate to return the address of a local variable to outside of the Functio n so you would has to define the local variable as? staticvariable.

Now, consider the following function, which'll generate random numbers and return them using an array and call this F Unction as follows:

#include<iostream>

#include<ctime>

?

Usingnamespace std;

?

function to generate and retrun random numbers.

int* getrandom(){

Staticint r[ten];

?

Set the seed

Srand ((unsigned)time( NULL ) );

?????

for ( int I = 0 ; I < 10 ; ++ i Span style= "COLOR: #666600" >) {

R [i] = rand();

cout << R [i] << endl;

}

?

return R ;

}

?

Main function to call above defined function.

int Main (){

A pointer to an int.

int*P;

?

P = Getrandom ();

?????

for ( int I = 0 ; I < 10 ; I ++ {

cout << " * (P + " << I Span style= "COLOR: #666600" ><< ;

cout << * (P + i)<< endl;

}

?

return0;

}

When the above code is compiled together and executed, it produces result something as follows:

624723190

1468735695

807113585

976495677

613357504

1377296355

1530315259

1778906708

1820354158

667126415

* (p + 0): 624723190

* (P + 1): 1468735695

* (P + 2): 807113585

* (P + 3): 976495677

* (P + 4): 613357504

* (P + 5): 1377296355

* (P + 6): 1530315259

* (P + 7): 1778906708

* (P + 8): 1820354158

* (P + 9): 667126415
