malloc与sizeof的合用的陷阱
This is a line of code written in C programming language. It is an example of dynamic memory allocation using the malloc() function.
The line of code declares a pointer variable T of type Elemtype, and dynamically allocates memory for three elements of type Elemtype using the malloc() function.
The if statement checks if the memory allocation was successful or not. If the allocation fails and returns NULL, the program exits with an error message of "OVERFLOW".
In summary, this line of code dynamically allocates memory for three elements of a specific data type and checks if the allocation was successful. If not, the program exits with an error message.
