This C Tutorial explains the differences between the while and for loop in C. While Loop In while loop, condition is checked before execution of each iteration and as condition fails, loop terminates. While Loop Syntax /* * In while, condition is tested in the beginning of each iteration */ while (condition) { … Read more
This Tutorial explains various loops in C with example usage. A loop statement is one that repeatedly executes, ensuring a given condition to be true prior to execution of each iteration, to perform some computations/work. As the condition turns false, loop terminates. There are three types of loops in C programming language. While Loop For … Read more
This C Tutorial explains the difference between While and Do-while Loop in C Programming. Do-while Loop in C In do-while loop, condition is always tested after the execution of the iteration and if condition fails, loop terminates. Therefore, do-while loop executes at least one iteration before termination if condition fails in first iteration! Do-while loop … Read more

This C Tutorial explains Linkage/Scope of variables and functions in C with examples and defines the type of Linkages. Linkage of any variable and/or function defines the Area of the Program in which they are accessible. There are three types of Linkages for the variables & functions. These are as follows 1. EXTERNAL 2. INTERNAL … Read more
Question: What is the difference between declaration and definition of a variable? Answer: Declaration specifies the properties of a variable. For example: int x; /* x is an integer */ int roll_no[]; /* roll_no is an array of integers */ Definition declares a variable and causes the storage to be allocated. For example: int x … Read more
This C Tutorial explains “Dangling else” in C. It explains the association of single else statement in a nested if statement. In nested if statements, when a single “else clause” occurs, the situation happens to be dangling else! For example: if (condition) if (condition) if (condition) else printf("dangling else!\n"); /* dangling else, as to which … Read more
Question: What is the output for the following code snippet? Will the program get compiled? If not, can you correct the condition in the if statement? if (;) printf("empty statement ; is considered true!"); else printf("empty statement ; is considered false"); Answer: COMPILATION ERROR! Well! if the empty statement ” ; ” in the if … Read more
This C Tutorial explains run time stack in C with examples. Lets dig deeper into details in order to unfurl the essentials of “Run-Time Stack” rather simply defining what Stack is and where is it used? Well! If we try to recollect ours’ memory during studying in college, we will find the concept of Stack … Read more
