Programming in Java has always been fun for me. With this post I begin the Java programming tutorials journey. In this post, we will learn how to write a simple Hello world program in Java. We will learn basic structure of a Java program, how to write, compile and execute a Java program.
Basic
C program to perform input output of all basic data types
Write a C program to demonstrate input and output of all basic and derived types. How to use scanf() and printf() function perform input and output on primitive types in C programming.
How to find range of data types in C programming?
In C programming data types play a major role, so is their size and range. The sizeof() operator gives you bytes required to store value of some type in memory. However, in programming you must be aware of range of a type to avoid overflow and underflow errors.
The size of a data type is compiler dependent and so is its range. So, you must not hardcode size and range values in your program.
There are two ways to find minimum and maximum range of a type. You can use any of the approach to get range of a type.
C program to convert days to years weeks and days
Write a C program to input number of days from user and convert it to years, weeks and days. How to convert days to years, weeks in C programming. Logic to convert days to years, weeks and days in C program.
Example
Input
