bitset operator[] in C++ STL
bitset::operator[] is a built-in function in C++ STL which is used to assign value to any index of a bitset.
Syntax:
bitset_operator[index] = value
Parameter: The parameter index specifies the position at which the value is to be assigned.
Return Value: The function returns the value to the bit at the index.
Below programs illustrate the bitset::operator[] function.
Program 1:
C++
// C++ program to illustrate the // bitset::operator[] #include <bits/stdc++.h> using namespace std; int main() { // Initialization of bitset // by zeros of size 6 bitset<6> b; // initialises second index as 1 b[2] = 1; // initialises fifth index as 1 b[5] = 1; // prints the bitset cout << "The bitset after assigning values is: " << b; return 0; } |
Output:
The bitset after assigning values is: 100100
Program 2:
C++
// C++ program to illustrate the // bitset::operator[] // assign value from a index #include <bits/stdc++.h> using namespace std; int main() { // Initialization of bitset // by zeros of size 6 bitset<6> b; // initialises second index as 1 b[2] = 1; // initialises fifth index as the same as b[2] b[3] = b[2]; b[0] = b[5]; // prints the bitset cout << "The bitset after assigning values is: " << b; return 0; } |
Output:
The bitset after assigning values is: 001100
Program 3:
C++
// C++ program to illustrate the // bitset::operator[] // prints the value of bit at index #include <bits/stdc++.h> using namespace std; int main() { // Initialization of bitset // by zeros of size 6 bitset<6> b; // initialises second index as 1 b[2] = 1; // initialises fifth index as the same as b[2] b[3] = b[2]; b[0] = b[5]; cout << "The bit value at index 3 is " << b[3]; return 0; } |
Output:
The bit value at index 3 is 1
