Answer:
Following are the program in the C++ Programming Language.
//set header file or namespace
#include <iostream>
using namespace std;
//define main function
int main() {
//set integer type array with indexing 10
int a[10];
//set integer type variable to 1
int i=1;
//set element in 1st index
a[0]=17;
//set element in last index
a[9]=29;
//set while loop for the remaining elements
while(i<9)
{
//set -1 in the remaining elements
a[i]=-1;
i++;
}
//set for loop to print array
for ( int j = 0; j < 10; j++ ) {
cout << a[j]<<endl;
}
}
<u>Output:</u>

- Set integer data type variable "i" initialize to 1.
- Set elements in the first and last place in the array.
- Set the while loop to initialize elements for the remaining place.
- Set the for loop to print the array elements.
