What will be the output of the following C code?

#include <stdio.h>
    typedef struct NN
    {
        int n, m;
    }s = {11, 22};
    int main()
    {
        NN nn = s;
        printf("%d\n", nn.n);
    }

1. Depends on the standard
2. 11
3. 22
4. Garbage value
5. Compilation Error

Correct Option: E

Compilation Error

     }s = {11, 22};
     ^

         printf("%d\n", nn.n);
