Using String Library Function A string is nothing but an array of characters. The value of a string is determined by the terminating character. Its value is considered to be 0. As it is evident with the image uploaded above, we need to enter both the strings which we need to concatenate ...
Heap是堆,stack是栈。 Stack的空间由操作系统自动分配/释放,Heap上的空间手动分配/释放。 Stack空间有限,Heap是很大的自由存储区 C中的malloc函数分配的内存空间即在堆上,C++中对应的是new操作符。 程序在编译期对变量和函数分配内存都在栈上进行,且程序运行过程中函数调用时参数的传递也在栈上进行 ...

NSString*string=@"Hello world"; 这种语法基本上是照搬C语言的,它声明了一个名为string的变量,其类型是NSString*。也就是说此变量为指向NSString的指针。所有OC语言的对象都必须这样声明,因为对象所占内存总是分配再“堆空间”(heap space)中,而绝不会分配在“栈”(stack)上。
