Convert Decimal To Octal program

A decimal number is taken and converted into its octal equivalent.

Example:

Decimal number: 50

Corresponding octal number: 62

Algorithm

Create a long integer variable called dno and prompt the user to enter a decimal number using the cout and cin functions.
Initialize a long integer variable called temp to the value of dno.
Create an array of integers called octal with a size of 100 and an integer variable called i initialized to 1.
Use a while loop to repeatedly divide temp by 8 and store the remainder in the octal array at index i. Increment i and assign the result of temp divided by 8 to temp. The loop should continue until temp becomes 0.
After the loop, use a for loop to iterate over the octal array starting at index j equal to i - 1 and ending at index j greater than 0. Inside the loop, print the value of octal[j] using the cout function.

Code:

#include <iostream>\nusing namespace std;\n\nint main() {\n    long dno, temp;\n    int octal[100], i = 1, j;\n\n    cout << \"Enter the decimal number: \";\n    cin >> dno;\n\n    temp = dno;\n\n    while (temp != 0) {\n        octal[i++] = temp % 8;\n        temp = temp / 8;\n    }\n\n    cout << \"Equivalent octal value of decimal no: \";\n    for (j = i - 1; j > 0; j--) {\n        cout << octal[j];\n    }\n\n    return 0;\n}\n\n

Output

Enter the decimal number: 123\nEquivalent octal value of decimal no: 173\n\n
