Question

R7.1 Carry out the following tasks with an array:

(A) Allocate an array a of ten integers.
(B) Put the number 17 as the initial element of the array.
(C) Put the number 29 as the last element of the array.
(D) Fill the remaining elements with –1.

Answer 1

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;

}

}

Output:

17

-1

-1

-1

-1

-1

-1

-1

-1

29

Step-by-step explanation:

In the following program, we define the main function "main()" and inside it.

• Set an integer type array element "a[]" with index value 10.
• 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.
