The substr function in C++ takes two parameters: the starting index and the number of characters to extract from the starting index. In this case, the starting index is 1 (which corresponds to the second character in the string, since the first character has an index of 0) and we want to extract 4 characters. Therefore, the resulting string will be "BCDE".
