Question
*C++ Write a function to reverse a sound. Reference the function void process(int samples[], int size) provided in sound.cpp to write your own function reverse. The two parameters in process function are array samples of int type and the size of this array. reverse should take the same parameters in the same order and modify the samples[] array so that the elements are in reverse order. The function will not return any values.
Examples [0, 1, 2, 3] --> [3, 2, 1, 0] [3, 2, 1, 0] --> [0, 1, 2, 3] [5, 8, 3, 10] --> [10, 3, 8, 5]
void process(int samples[], int size)
{ // Here, we make the sound three times as loud
for (int i = 0; i < size; i++)
{ samples[i] = 3 * samples[i];
}
}
Explanation / Answer
void reverse(int* samples, int size)
{
int i=0, j=size-1;
while(i<=j)
{
int temp = samples[i];
samples[i] = samples[j];
samples[j] = temp;
i++;
j--;
}
}
