The function realloc () is used to resize the memory allocated earlier by function malloc () to a new size given by the second parameter of the function. The function realloc(ptr,n) uses two arguments.the first argument ptr is a pointer to a block of mem
In the realm of C programming, efficiently managing memory is crucial for building high-performance applications. One of the tools at a programmer’s disposal for such a task is malloc(), a function that dynamically allocates memory during runtim
the program break does not changed. So, it shows that at the initial stage of the execution of the program, the heap does not contain memory. Once the malloc is called then only the heap memory is allocated with the use of sbrk function. Is it...
Dynamic memory can refer to memory that is provided to programs as needed. It can also refer to memory that requires a device to rewrite the... Learn more about this topic: Computer Data Storage | Overview, Memory & Function from
1:In C,void*can be used as a return value and function parameter but in C++ you must have a specific data type of pointer. For example: In C, the code is given below: #include <stdio.h> #include <stdlib.h> void*add_numbers(inta,intb){ ...
In C, dynamic memory (i.e., memory allocation is not known in advance) is allocated using themallocfunction and deallocated usingfree. Programmers were expected to manage memory manually. As a result, memory leaks were common errors in C code. ...
I am writing a python script that requires a reverse complement function to be called on DNA strings of length 1 through around length 30. Line profiling programs indicate that my functions spend a lot of time getting the reverse complements, so I am loo

What is string in C programming language? How is a programming language is created? What is a function in computer programming? When was C programming language invented? (a) What are the usages of math functions in C language? (b) Explain extendedly all the inbuilt math functions in the ...
On the other hand, malloc is a standard memory allocation function in C programming, used to allocate a specified amount of memory on the heap. It is commonly used for dynamic memory allocation where the size of the memory needed isn't known at compile time. 11 Mmap provides the advantage...
