You can initialize an array of characters (or wide characters) with a string literal (or wide string literal). For example:复制 char code[ ] = "abc"; initializes code as a four-element array of characters. The fourth element is the null character, which terminates all string literals.An...
string1 = [NSMutableString stringWithString: @"This is a string"]; // Initialize string1 string2 = [NSMutableString stringWithString: string1]; // Copy string1 object to string2 [string2 appendString: @" and it is mine!"]; // Modify string2 NSLog (@"string1 = %@", string1); NS...
You can initialize strings in a number of ways. charc[] ="abcd";charc[50] ="abcd";charc[] = {'a','b','c','d','\0'};charc[5] = {'a','b','c','d','\0'}; String Initialization in C Let's take another example: ...

[6.7.8.21] If there are fewer initializers in a brace-enclosed list than there are elements or members of an aggregate, or fewer characters in a string literal used to initialize an array of known size than there are elements in the array, the remainder of the aggregate shall be initialized...
}intmain(){aos_pool_t*p;oss_request_options_t*options;/* 初始化全局变量,在程序生命周期内只需要调用一次。*/if(aos_http_io_initialize(NULL,0) != AOSE_OK) {return-1; }/* 初始化内存池和options。*/aos_pool_create(&p,NULL);
因为对于单例的初始化有线程安全的问题,而Apple的文档中明确指出+(void)initialize调用是“in a thread-safe manner”。我们就不需要在+ (Printer *)instance考虑线程安全性问题了。 另外,如果static变量是方法外部作为全局变量的话,那么它放在@implementaion内还是外并没有关系,编译器都把它当做C的语法进行编译,并...
