What will be the output of the following program?

#includestdio.h

int main()
{
    char *str;
    str = "%d\n";
    str++;
    str++;
    printf(str-2, 300);
    return 0;
}

#include stdio.h
int main()
{
int a=366;
while (a375)
{
++a;
if (a=368&&a=372)
{ 
continue;
} 
printf("%5d"‚a);
}
return 0;
}

    #include stdio.h
    union Sti
    {
        int nu;
        char m;
    };
    int main()
    {
        union Sti s;
        printf("%d", sizeof(s));
        return 0;
    }

#include stdio.h
void solve() {
    int a = 3;
    int res = a++ + ++a + a++ + ++a;
    printf("%d", res);
}
int main() {

 return 0;
}
