Escoja la respuesta correcta para llenar el blanco. in c++ a block boundary (or scope) is defined with a pair of braces {} parentheses () quotes ' ' brackets []

Braces {}.

Explanation:

In C++ the boundary of a block are defined by the {} braces.

() parentheses are used to pass arguments to the functions.

[] brackets are used to mention the size of the array.

' ' quotes are used for characters.

for ex:-

int main()

{                  //line 1

   for(int i=0;i<10;i++)

{                  //line 2

cout<<i<<" ";

}                //line 3

cout<<endl;

return 0;

}               //line 4

The boundary of for loop is from line 2 to line 3 and the boundary of main function is line 1 to line 4.
