printf的使用

ASC C之后引入的一个特性是，相邻的字符可以被自动连接

 1 #include <iostream>
 2 using namespace std;
 3
 4 int main() {
 5     printf("abcd"
 6         "efg\n");
 7
 8     char* var[] = {
 9         "adf",
10         "def"
11         "ghi",
12     };
13
14     printf("size of var is: %d\n", sizeof(var)/sizeof(var[0]));
15
16     for(size_t sz = 0; sz < sizeof(var)/sizeof(var[0]); sz++)
17         cout << var[sz] << endl;
18
19     return 0;
20 }

$ ./a.exe
abcdefg
size of var is: 2
adf
defghi
