In C, after arrays, structures are the most important data structure available for programmers. We shall understand different ways to initialize memory to structure and accessing elements inside a structure. Creating simple structure and accessing elements inside them In this example, we shall create a structure …
There is no separate data type in C to hold strings. In C, strings are character array. They should always end with NULL “\0” character. While allocating memory for strings, space should be allocated for NULL character also. C allows us to create a static strings …
Before we understand the relationship between pointers and arrays, let us see some basic examples of arrays. Statically allocated arrays The size of the array known at compile time is called as statically allocated arrays. The memory will be given in the program stack. They are …
A function pointer is a pointer that holds the memory address of a function. How to declare a function pointer in C? Consider the function prototype as below: void sum (); According to the above function prototype, the function sum will not take any arguments, and …
int *ptr; *ptr = (int*) malloc(10); Dynamic Memory Management Introduction. C provides a way to allocate memory at runtime. This is done with the help of DMM. This is a very important feature in C language, and yet programmers seldom makes mistake while writing a program …
Operations that can be performed on Addresses: WKT pointer variable will hold the address of another variable. i.e int a = 10; int *ptr = NULL; ptr = &a; Now, If you print “ptr”, it will print the value that is stored inside it. i.e the …
In this chapter we shall learn about below topics: git revert git bisect git grep git reset git revert “git revert” is similar to “git reset”. But we use git revert, when the changes are already committed to remote repository. Suppose you have committed 3 times …
