Predict the output:

int main()
{
    char k='A';
    char k1='b';
    char k2='B';
    switch(k,k1,k2)
    {
        case 'a':
        case 'A':
        printf("messi");
        break;
        case 'b':
        case 'B':
        printf("messi argentina");
        break;
        default: printf("football");
    }
    return 0;
}
