বাংলায় কম্পিউটার প্রোগ্রামিং | C Programming in Bengali

In this practical session, we will see how to declare variables and assign values to them. We will also learn how to show them on screen. Moreover, we will learn how to take input from the user. While we are going well with them, we perform calculations using arithmetic expressions.

In this practical session, we will get more insight into Variables & Data type and an application. We will take inputs from the keyboard and show the output in the screen.

In this practicals session, we will make a Mini Project based on the learnings of the above three lacture. It will be fun!

In this practical session, we will take a look at decision making with C keywords if, else if and else. There are subtle mechanisms and differences among them.

In this tutorial, we will learn how to determine whether a number is odd or even.

In this practical session, we will learn about looping- the most important part of the basic programming. There is a minor difference between the working of while and do-while loops. This difference is the place where the condition is tested. The while tests the condition before executing any of the statements within the while loop. In contrast, the do-while tests the condition after having executed the statements within the loop. do-while would execute its statements at least once, even if the condition fails for the first time. The while, on the other hand will not execute its statements if the condition fails for the first time.

We have seen that arrays are data structures that represent a list of values of the same type and same name. The elements of an array are denoted by index. We have developed a “Summing” technique in many of our previous lab works and in theory classes where we take a variable total initializing it with 0. Inside a loop, we increase the variable by adding another variable consistently.

In this practical session, we will take a look at strings and recursion and will try to blend them together. In the previous lab, we already have introduction of strings and how pointers can access a string. This aspect is very important. As I said, if you know pointer, you can do any program in C- let’s see how much of that speech is true.

Pointers in C are easy and fun to learn. Some C programming tasks are performed more easily with pointers, and other tasks, such as dynamic memory allocation, cannot be performed without using pointers. So it becomes necessary to learn pointers to become a perfect C programmer. Let's start learning them in simple and easy steps.

A function in C can perform a particular task, and supports the concept of modular programming design techniques. We have already been exposed to functions. The main body of a C program, identified by the keyword main, and enclosed by the left and right braces is a function. It is called by the operating system when the program is loaded, and when terminated, returns to the operating system.
