C language programs stop and continue to run

The reason why the exe stops working when the C program runs is because of a memory overflow and a compiler error.

Type 1: Memory overflow.

Out of memory is commonly understood as insufficient memory, and the memory required by the program far exceeds the size of the memory installed in the host, which is called memory overflow. The system will prompt a memory overflow, sometimes the software will be automatically closed, and the software can run normally after restarting the computer or releasing a part of the memory after the software.

Second: compiler errors.

Some compilers may use different standards (for example, the C99 standard may be used on one machine, and the C11 standard may be used on another machine), or because the compiler link library is damaged, in a few cases, it may also cause the program to have abnormal errors that are not limited to crashes and exits, and the solution is usually to install the latest version of the compiler's official IDE.

Examples: 1. Divide by zero.

2. Array out-of-bounds: int a[3]; a[10000000]=10。

3. The pointer is out of bounds: int * p; p=(int *)malloc(5 * sizeof(int));p+1000000)=10。

4. Use the space that has been released: int * p; p=(int *)malloc(5 * sizeof(int));free(p); p=10。

5. The array is too large and beyond the scope of the stack, causing the stack to overflow: int a[100000000], and the memory is not opened up list l=(list)malloc(sizeof(struct lnode)). Runtime error is when a program crashes halfway through running.

KBHIT() is a C and C++ function that DAO is used to respond to keyboard input events in a non-blocking manner. Answer.

Function name: kbhit().

Function and return value: Check whether there is currently a keyboard input, if there is, return a non-0 value, otherwise return 0.

Usage: int kbhit(void);

The C++ language contains header files: include.

The C language does not need to contain additional header files.

The function and return value are the same as above.
