Transfer 001 C / C ++ array

Passing an array to a function in the right way:

1. First pass the memory address of the array.

2. The effective length of the array is passed. Number of elements of the group index.

---

 

The compiler always array type variable passed as a pointer.

Calculating the length of the array: int length = sizeof (a) / sizeof (a [0]); 

---

C Sample code:

// accepts an array parameter function declaration: 
void SampleArray1 ( int * A, int length) 
{ 
    for ( int I = 0 ; I <length; I ++ ) { 
        the printf ( " % D " , A [I]); 
    } 
    the printf ( " \ n- " ); 
} 

void SampleArray2 ( int A [], int length) 
{ 
    for ( int I = 0 ; I <length; I ++ ) { 
        the printf ( " % D ", a[i] );
    }
    printf( "\n" );
}

void SampleArray3( int a[7], int length )
{
    for( int i = 0; i < length; i++ ) {
        printf( "%d ", a[i] );
    }
    printf( "\n" );
}

void main()
{
    int a[] ={ 1,5,8,9,10};
     Int length = the sizeof (A) / the sizeof (A [ 0 ]); // . Calculating the length of the array 

    // compiler always array type variable passed as pointers 
    SampleArray1 (A, length); 
    SampleArray2 (A , length); 
    SampleArray3 (a, length); 
    SampleArray1 ( & a [ . 1 ], length - . 1 );   // array is passed to the last element of the second element to function.
