What will be the output of the following code?#include<iostream>using namespace std;void func(int a, int b) { cout << (a + b);}int main() { int a = 7; func(a, 12);}Options: Pick one correct answer from below12151929

The output of the code will be 19.

Here's the step by step explanation:

1. The main function is called first in C++ program.

2. In the main function, an integer 'a' is declared and initialized with the value 7.

3. Then, the function 'func' is called with two arguments: 'a' (which is 7) and 12.

4. Inside the function 'func', the two arguments are added together (7 + 12) and the result is printed out using 'cout'.

5. So, the output of the program will be 19.
