C++. Write a function to transform a decimal number into a binary number. The function must receive a positive integer value as a parameter and must return a string with the binary representation of the number.

Given the integer value 7, the return value of your function must be the string: 111

Iterative process to convert a decimal number to binary format:

• Divide the number by 2; the remainder is the first digit of your binary number (least significant). Example: 7%2 = 1
• Subtract the remainder from your number and divide what's left by 2. Example: (7 - (7%2))/2 = 3
• Repeat and concatenate new digits to the front of the binary number. 3%2 = 1 --> 11

Hint: you can use the function to_string (string to_string (int val)) to transform an integer value into a string.
