I would like to write about unreachable code in C and C++ and about the pertinent compiler warnings in this context. Sometimes, entire blocks of our C or C++ source codes are unintentionally cut off from the control flow. Consider the following demon...
Structures Also known as Aggregates Collection of variables under on name May contain variables of different data types Derived data types Commonly used to store records in files Getting member information from an instance uses the dot oper...
Sorting: qsort (stdlib.h) void qsort(void *base, size_t nitems, size_t size, int (*compar)(const void *, const void *)) void *base: Starting address size_t nitems: number of items to sort size_t size: size in bytes for each element int (*compar)...

I finally went out of my way to create my own original project—the Guitar Chord Generator. It lets users search for a chord and gives them the correct capo fret position along with an updated chord. It also generates chord progressions using the I-IV...
We all have created many files, forgotten about it and left it unattended. If you have run my Directory Structure Generator program uploaded earlier it has created many empty files which is not useful. This program solves this issue. This is a straig...
This C program copies a file from one place to another through a system call. The user supplies the source and destination file names as arguments, and the program executes a Linux shell command to do the copy. How It Works The program has two argume...
Strings and characters A program may contain character constants. The value of a character constant is the integer value. There is a table that represents the ASCII character set. A string is a series of characters treated as a single unit A str...
Simulate pass by reference When we pass a variable, we pass the variable to the function. When we pass the address, we simulate pass-by-reference. void pass_by_value(int a); copies the value into the function void pass_by_reference(int *a); passes...
