Converting one type of data to another type is the key thing when we deal with data using programming languages. C language supports this data conversion, and provides functions to ease our programming in C. Through this article we are going to discuss about atoi and itoa data conversion functions. atoi function This function is […]
Some times it is required to edit the Windows Shortcuts to update the shortcut to point to new location/program. But Windows will not allow to edit the disabled shortcuts (it is not possible to update the Target value through Properties window manually). We can write simple VBS (Visual Basic Scripting) to update the shortcuts to […]
Lists are popular, commonly used, and very useful data structures; directly or indirectly used in most the Applications. Lists are sequences of structures where data is placed in individual blocks. Each block (we call it, a Node or an Element) contains a data part and an address part which points to another block to form […]
Pointers play a major role in C Programming. Writing code with pointers is more error-prone than code without pointers. Understanding pointers is a bit difficult. The simple thing about a pointer is, a pointer is a variable that holds an address like variables holds a value. That means pointers will not store any values rather […]
We can create arrays in different ways in C. We already discussed creating non-dynamic arrays in C in our earlier article “C Programming – An introduction to Arrays“; I recommend you to read it before reading this article. Through this article, we are going to discuss how to create arrays dynamically in C. Create arrays dynamically […]
An HTML <div>tag is used to define a section in an HTML document. This tag is more often used to create web-layouts. Some times, it is required to place two <div> tags side by side. As it is not straight forward, below steps are helpful to achieve this: Step 1. First, write the HTML code […]
Sometimes we may need to convert a string to either lowercase or uppercase depending on the program requirement. We have a set of functions in C Library to convert a string to either lowercase or uppercase. Note that, these functions are not standard library functions, and you may or may not see these functions in […]
As we discussed in, Understanding of Pointers in C, pointers are address holders. Pointers point to an address of a variable, or a function or even it can point to another pointer. Through this article, we are going to discuss Pointer to Pointer concepts in C. A pointer to pointer points to an address of […]
C library has string functions to compare whether the given strings are identical or not. strcmp library function This function takes two arguments, both are strings. Compare the strings and return 0 if the strings are identical; otherwise, this function returns a non-zero value. What is the meaning of non-zero value? When the first string […]
Pointers are address holders, points to something. Each variable or function in the C language has an address. When a variable is defined, it occupies some memory, in the process memory space. When we assign a value to the variable, the value will be stored in the address of the variable. Through this article, we […]
