The best thing you could do is try gain as much knowledge as you can and as early as possible. Nobody is a genius upon birth, so it’s all right to not know much at first. Therefore, the fix to this problem is to try to learn a lot. I learned that it was difficult for me only because I didn’t know a lot at that time. But when I learned more I realized they were right. That’s because I thought they were downplaying my sentiments. Of course, I was embarrassed and annoyed at the same time.
They told me the homework was pretty simple. I thought the homework was tough, and then some guys came up to me and laughed. When I started programming, I was always cursing under my breath, simply because I didn’t understand a single thing. If you can’t wrap your head around something, it may be that your skills are not honed enough yet.
Java Runtime Environment is the software layer that is used to run Java applications.

This wikiHow teaches you the basics of how to get started programming with Java. Other operators such as ternary operator ?:, reference operator &, dereference operator * and member selection operator -> will be discussed in later tutorials.The most obvious reason why you might find homework difficult is that it’s just beyond you. With Java, you can develop apps for multiple operating systems with minimal work. Printf("Size of char=%lu byte\n",sizeof(d)) Printf("Size of double=%lu bytes\n",sizeof(c)) Printf("Size of float=%lu bytes\n",sizeof(b)) Printf("Size of int=%lu bytes\n",sizeof(a)) The sizeof is a unary operator that returns the size of data (constants, variables, array, structure, etc). Other OperatorsĬomma operators are used to link related expressions together. Visit bitwise operator in C to learn more. (a = b) & (c 5) evaluates to 1 because both operands (a = b) and (c > b) is 1 (true).
Printf("(a = b) & (c > b) is %d \n", result) If c = 5 then, expression !(c=5) equals to 0.Įxample 5: Logical Operators // Working of logical operators If c = 5 and d = 2 then, expression ((c=5) || (d>5)) equals to 1. Relational operators are used in decision making and loops. If the relation is true, it returns 1 if the relation is false, it returns value 0. The most common assignment operator is = OperatorĮxample 3: Assignment Operators // Working of assignment operatorsĪ relational operator checks the relationship between two operands. Visit this page to learn more about how increment and decrement operators work when used as postfix.Īn assignment operator is used for assigning a value to a variable. These two operators can also be used as postfixes like a++ and a. Here, the operators ++ and - are used as prefixes. Example 2: Increment and Decrement Operators // Working of increment and decrement operators These two operators are unary operators, meaning they only operate on a single operand. Increment ++ increases the value by 1 whereas decrement - decreases the value by 1. Either one of the operands is a floating-point numberĬ programming has two operators increment ++ and decrement - to change the value of an operand (constant or variable) by 1. The % operator can only be used with integers. When a=9 is divided by b=4, the remainder is 1. The modulo operator % computes the remainder. The compiler neglects the term after the decimal point and shows answer 2 instead of 2.25. It is because both the variables a and b are integers. The operators +, - and * computes addition, subtraction, and multiplication respectively as you might have expected.
