Many students compains that they are unable to use graphics.h library in c programs. This is true for most of the systems. graphics.h library do not work on new laptops and desktop. I used to use this libray on my old desktop that I purchased in 2002. Although In my opinion if students are taught using graphics programming than they will find it interesting and will spend more time to learn programming and hence they will learn better than the traditional way of teaching.read more...

This C program will print a right angled pyramid on computer screen. I write this program in code::blocks IDE.if you use some other compiler insert "getch();" at the end of the program and "conio.h" header file. #include<stdio.h> int main() { int i,j,lines; char ch = '*'; printf("Enter number of lines : "); scanf("%d",&lines); for(i=1;i <=lines;i++) // this loop will run lines times { for (j=0;j < i;j++) printf("%c ",ch); printf("\n"); } return 0; } ...

The program given below performs a very basic arithmetic instructions multiply that perform by * operator.we have used three variables in it. num1 and num2 will be entered by user.User will enter values of variables num1 and num2.Multiplication of these two variables will store in multiply variable.Finally value of multiply variable will gets printed on screen. #include<stdio.h> int main() { int num1, num2, multiply; scanf("%d %d",&num1,&num2); multiply = num1 * num2; printf("%d",multiply); } ...

In previous video I describe a simple c plus plus program. Although the program itself was working fine but still some very common things are missing in that program. one of them is comments, a very important part of a computer program written in any programming language. So, In this video I will show you how to write comments in a c++ program with the importance and application of comments. Single line comments and multiline comments are explained in this video....

Pankaj ask me this problem. His c program is behaving strange because of '\n', a escape sequence in c programming language. In this video I try to explain the behavior of that program. This video will give you answer to these questions - 1. What does \n in a scanf statement do 2. \n skips the second input... Read more

In our previous videos we have installed Code::Blocks& Dev-CPP IDE so that we can compile Cpp programs. Before this we have also learne what does program, instruction, mean. We have enough learn and do to write our first CPP program. So, lets watch this video and write first CPP program to print "Hello World" on computer screen.... Read more

In last video I show you how to install Dev-CPP compiler on your windows machine. Although there is one problem in that IDE. I find no way to watch result window without writing getch() in program. I don't want to use getch() just to see the result. Dev-CPP and Code::Blocks (Code blocks) both support MinGW (Minimal GNU compiler for Windows) and GCC (GNU Compiler Collection). So both work same way, you can use any one of them to build your program.Install Dev-CPP compiler to compile your C and Cpp programs on windows machine... Read more

This video demonstrate installation of Dev-CPP compiler on windows machine. This may be very easy for a tech-savvy student but most of the students in first year of graduation do not know how to do it. Follow the procedure shown in the video and install it now. It's necessary step in order to write a c plus plus program.Introducing C plus plus, second video of tutorial series "Yogi's guide to C++"... Read more

Most of the students know syntax of a programming language but face problem in developing logic. Today I am going to introduce you with a tool that will help you in learning programming in a fun way.  Although I have already introduced you to this tool before in my article "10 Tools to teach & learn programming concepts and increase logical ability". This programming tool is known as SCRATCH. SCRATCH is a block level programming language or visual programming language. It gives you power to visually create a program.read more... Read more
