Just do like this:

void printArrayElement(int a[], int i, int n) {
if (i < n) {
printf(" %d", a[i]);
printArrayElement(a, ++i, n);
}
}

no need to do any other thing

Because after printing last element i would be increase and garbage value will be print.

For example if element is 5 then i would be 5 but a[5] is nothing in the array so garbage value will come

Answer 3

The function printArrayElement() keeps printing until it finds a zero in memory. Unless you deliberately place a zero in the last element, it may keep printing past the end of the array until there happens to be a zero somewhere in memory. A quick fix to make this work would be to allocate one more element to the array size and assign a zero there.

int a[n+1]; //add one more element
printf("\nInput %d element in the array :",n);
for(int i=0;i<n;i++){
printf("\nElement - %d : ",i);
scanf("%d",&a[i]);
}
a[n] = 0; //force a terminating zero

Answer 4

C does not automatically initialize local arrays with zero.

After array declaration of n elements, the array is addressed by indices 0 through n-1. If you access arr[n] or arr[n+1] then it is outside the array boundary.

The two extra values that you see are the next two values that are found in memory past the end of the array.
