Function returning pointer to array in c programming.

char (*pa())[4];

void main(){

    char(*p)[4]=pa();

    clrscr();

    printf("%d",**p);

    getch();

}

char (*pa())[4]{

       static char arr[]={'\11','\12','\13','\14'};

       return &arr;

}

Output: 9

ONE MORE EXAMPLE:

int* insertion_sort();

void main(){

int *arr,i;

arr=insertion_sort();

clrscr();

for(i=0;i<=7;i++)

printf("%d ",arr[i]);

getch();

}

int * insertion_sort(){

static int arr[]={3,11,2,0,5,23,8,1};

int i,j,temp,s=8;

for(i=1;i<=s-1;i++)

{

temp=arr[i];

j=i-1;

while((temp<=arr[j]-1)&&(j>=0))

{

arr[j+1]=arr[j];

j=j-1;

}

arr[j+1]=temp;

}

return arr;

}

Output: 0 1 2 3 5 8 11 23
