Array of Pointers: If the array is Pointer type, it can store multiple references called Array of Pointers.
| #include<stdio.h> int main() { int arr[5] = {10, 20, 30, 40, 50}, i; int* ptr[5]; for(i=0 ; i<5 ; i++){ ptr[i] = &arr[i]; } printf(“Array elements are : \n”); for(i=0 ; i<5 ; i++){ printf(“%d \n”, *ptr[i]); } return 0; } |
We can access elements without using index as follows:
| #include<stdio.h> int main() { int arr[5] = {10, 20, 30, 40, 50}, i; int* ptr[5]; for(i=0 ; i<5 ; i++){ *(ptr+i) = arr+i; } printf(“Array elements are : \n”); for(i=0 ; i<5 ; i++){ printf(“%d \n”, **(ptr+i)); } return 0; } |
A function can return the string using char* return type.
| #include<stdio.h> char* read(void); int main() { char* name; name = read(); printf(“Name returned by read function is : %s \n”, name); return 0; } char* read(void) { char* name; printf(“Enter your name : “); gets(name); return name; } |
