Question

Assume the existence of a class Arr with two (public) data members: a pointer to integer named arr_ptr, and an integer variable namedlength that will contain the number of elements in the array. Assume the variable a has been declared to be of type Arr, an array has been allocated and assigned to arr_ptr, and length has been assigned the proper value (i.e., the number of elements in the array). Write the code to add 1 to each element of the array.

Answer 1

for(int i = 0;i<a.length;i++){
    a.arr_ptr[i] = a.arr_ptr[i] + 1; 
}
