For simplicity we divide our code into small pieces / modules known as functions. To use functions in C programming we need to define function prototype, function definition and finally we call the function to perform that functionality. Here we will…
Sometimes in C program we need to repeat statements for certain number of times. So in order to repeat statements for number of times we use repetition structure in C programming. There are 3 types of repetition structures available…
Do-while loop is also a type of repetition structure used to repeat statement(s) for certain number of times. The major difference between while and do while loop is that in do while loop the loop termination condition is checked…
For loop is also a type of repetition structure. This repetition structure is simpler in syntax as compared with other 2 loops because all four loop conditions can be defined in single line. Following simple program explains how to…
Sometimes in a program we need to get values from user, process the values entered by user and print / output the results of that processing on the screen. In order to get values from user we use ‘scanf’ function…
In our previous post we discussed about how to get values from user. Sometimes we need to define variables and assign values to those variables. This simple program explains how to define variables and how to assign values to the variables…
If statement is called as selection structure in C Programming. If statement checks a condition and proceed further depending upon the fact that whether the condition being checked is true or false. In simple words it says “Do something…
In previous post we discussed about if statement in C Programming. If-else statement called as double selection structure in C Programming. In simple words it says “Do something when a condition is true, else (when condition is false) do some…
Switch statement is also called as multiple selection structure in C Programming. Switch selection structure is similar to if-else selection structure. The difference is instead of using multiple if-else statement we use ‘cases’ to check for multiple conditions. The…
In C programming we use printf function (which is part of stdio.h library) to print / output some text or variable on the screen. Following simple C program outputs a text on the screen. It also explains how to move…
Hello World! program is used to start learning any programming language. This simple hello world program is written in C programming language. This simple program just print ‘Hello World!’ string on the output screen. We tried to explain each code…
