These programs are very easy as they only needs formula and so you can execute it perfectly. I have taken an example of an area of the square program. Remember that always create the logic in your mind like I want the area of a square so I want to know the formula i.e. ‘side * side’, side is just one variable which multiplies by itself. This answer should be stored in another variable called ‘area’. Finally, I need to print ‘area’ value as output.
From above logic, you can easily code. Likewise, you can have the question like an area of a circle, the area of the triangle, the circumference of circle blah blah blah. All you need to concentrate on formula and your work is done.
printf(“Enter the value of the side:”);
printf(“\n The Area of square is %d”,area);
Enter the value of the side:6
The Area of square is 36
\n is used to write in new line. It just acts like enter key to go to new line.
