45. The && is the AND operator, and follows the rule that if all individual conditions are TRUE, the entire statement is TRUE. For example: char planet = “Earth”; does two things: it declares a string variable named planet, then initializes it with the value “Earth”. When using this operator, all conditions specified must be TRUE before the next action can be performed. In C programming, linked lists are created using pointers. Queues Before a program can be written, an algorithm has to be created first. Yes, you don’t have to write a separate assignment statement after the variable declaration, unless you plan to change it later on. When using getch(), the key that was pressed will not appear on the screen, and is automatically captured and assigned to a variable. Header files contain the definition and prototype for functions and commands used in a C program. FALSE. No. One common instance wherein run-time errors can happen is when you are trying to divide a number by zero. The... What is HDFS? You can then use it as PI in the program, instead of having to write 3.1415 each time you need it. Header files or library files have the .H file extension. Within the main function lies the variable declaration and program statement. It comes handy as an interview and exam guide for computer scientists. There are 3 main control structures in programming: Sequence, Selection and Repetition. C language is a case sensitive language. Placing & means whatever integer value is entered by the user is stored at the "address" of the variable name. Interpreters execute program codes one line at a time, while compilers take the program as a whole and convert it into object code, before executing it. keyword used in a function?

It takes two parameters, the source string and the string value to be appended to the source string. One is that it was designed to loop continuously until the condition within the loop is met, after which a break function would cause the program to step out of the loop. Medical Coding Interview Questions / Job Guide — VIDEO. Why? Binary trees are actually an extension of the concept of linked lists. What is constructor in java?Answer: A constructor is a special method used to initialize objects in the java.we use constructors to initialize all variables in the class when an object is created. Comments are mostly for the guidance of the programmer only and do not have any other significant use in the program functionality. This means that program flow may not necessarily move from one statement to the next one, but rather some alternative portions may need to be pass into or bypassed from, depending on the outcome of the conditional statements. 61. The = symbol is often used in mathematical operations. void = 10; The word void is a reserved word in C language. (for double quote). 42. How do you determine the length of a string value that was stored in a variable? Any class that contains one or moreabstract methods is declared as abstract. This propagation continues till it finds anappropriate exception handler, if it finds handler it would be handled otherwise program terminatesAbruptly. Any class which extends the vehicle will provideits method implementation. This question is a great example of a common question that covers two categories, Personality Traits and Communication Skills. You can also use ?unsigned int?, assuming you don?t intend to store negative values. A misplaced symbol, or lack of symbol, somewhere within a line of code can also lead to syntax error. The number after the decimal point sets the number of decimal places, in this case, it's 2 decimal spaces. myName = “Robin”; You cannot use the = sign to assign values to a string variable. That's because memory in this structure can be allocated and remove in any particular order. Instead, use the strcpy function. myName = "Robin"; You cannot use the = sign to assign values to a string variable. Note that this function will only convert a single character, and not an entire string.
