<span>C. Documents that convey buyers, sellers, and purchases made</span>
Answer:
Since the language isn’t stated, I’ll give answers in the two most-used (?) languages: Java and Python.
a) To print a’s value 3 times in the same line, in Java we would do:
System.out.print(a+a+a);
In Python, we would write:
print(a*3)
b) 2 times in different lines using one print statement
In Java, we would write
System.out.println(a+”\n”+a+”\n”+a);
In Python we would write:
print(a,a,a,sep=’/n’)
Hope this helps!
The answer would be <span>It is designed to promote social interaction and community building.</span>
