Fix Malloc Allocation Failure in C

1. Check the memory availability: Before calling the malloc function, you can check the current memory usage of the system using system functions to ensure that there is enough memory available for the program to allocate.
2. Check for memory misuse: If there are memory leaks or fragmentation issues in the program, it may lead to insufficient memory. Using a memory checking tool can help examine the program’s memory usage.
3. Optimize memory usage by utilizing memory pools or object pools to reduce frequent memory allocation and deallocation, ultimately improving memory efficiency.
4. Using appropriate data structures and algorithms in the design can reduce memory usage and improve memory utilization.
5. Error handling: After calling the malloc function, it is important to promptly check if the return value is NULL. If it is NULL, it means that the memory allocation has failed and proper error handling is needed, such as releasing previously allocated memory and prompting the user to try again.

In conclusion, addressing the issue of failed malloc memory allocation requires a comprehensive consideration of system resources, program design, and memory usage, leading to rational optimization and adjustment.
