What will be the output of the following code snippet?123456#include <stdio.h>int main() { int a = 4, b = 7; printf("%d", a & b); return 0;}

The output of the code will be 4.

Here's the step-by-step explanation:

1. The code declares two integer variables, a and b, and assigns them the values 4 and 7 respectively.
2. The printf function is used to print the result of the bitwise AND operation (&) between a and b.
3. The bitwise AND operation works on the binary representations of a and b. The binary representation of 4 is 0100 and of 7 is 0111.
4. The bitwise AND operation compares each bit of the first operand (a) to the corresponding bit of the second operand (b). If both bits are 1, the corresponding result bit is set to 1. Otherwise, the result bit is set to 0.
5. So, 0100 (4 in binary) AND 0111 (7 in binary) gives 0100, which is 4 in decimal.
6. Therefore, the output of the code is 4.
