These are a point to some arbitrary memory location and can cause bad program behavior or program crash. The switch statement is best used when dealing with selections based on a single variable or expression.

Why C Programming

However, some programmers prefer declaring the structure globally, then pass a variable of that structure type to a function. This is followed by the main function heading. Ans Uninitialized pointers in the C code are known as Wild Pointers. If a break statement was not placed at the end of a particular case portion?

When you create and use functions that need to perform an action on some given values, you need to pass these given values to that function. But when we declare a variable it has a direct reference to the value.

Repetitions are also known as loop structures, and will repeat one or two program statements set by a counter. Ans The purpose of the Break keyword is to bring the control out of the code block which is executing. Therefore, source codes are compiled using a compiler. Storing data on the heap is slower than it would take when using the stack. When declaring functions, you will decide whether that function would be returning a value or not.

Those reserved words have special meaning and it is not possible to use them for any activity other than its intended functionality. This concept de-refers twice to point to the data held by a pointer variable. Using dynamic memory allocation, your program will access memory spaces as needed. Flowcharts are made of symbols, with each symbol in the form of different shapes.

However, the main advantage of using the heap is its flexibility. This is where library files are specified, which would depend on what functions are to be used in the program. Endless loops are oftentimes referred to as infinite loops. Preprocessor directives begin with the symbol.

It can be placed anywhere in the program. Ans A loop running within another loop is referred as a nested loop. It can appear only in Looping or switch statements. In this example Name of the function is Sum, the return type is integer data type and it accepts two integer parameters.

Random numbers are generated in C using the rand command. When using Call by Value, you are sending the value of a variable as parameter to a function, whereas Call by Reference sends the address of the variable.

It is the process of transferring data to an alternative output source other than the display screen. Ans A statement that allows executing statement or group of statements in repeated way is defined as a loop. It takes two parameters, the source string and the string value to be appended to the source string. For comparing string values, there is another function called strcmp that deals specifically with strings.

Declaring all header files in every program would only increase the overall file size and load of the program, and is not considered a good programming style. In C programming, arch and garch models pdf source codes are saved with the file extension. Ans The process of dividing the main program into executable subsection is called module programming. Can u provide these questions as pdf Reply.

Ans A function, which has a function definition prefixed with a static keyword is defined as a static function. It has to do with the parsing process and compilation of the code. To access a particular data within the sequential access file, data has to be read one data at a time, until the right one is reached. Some Tricky Question Answers.

Another idea of an endless loop is when an incorrect loop condition was written, causing the loop to run erroneously forever. Note that this function will only convert a single character, and not an entire string. Following sample code demonstrate the use of rand. Compilers and interpreters often deal with how program codes are executed. Ans There is no possibility to add pointers together.

An algorithm provides a step by step procedure on how a solution can be derived. Only top of the stack is accessible at a given instance.

This indicates the point that new line need to start to the compiler and the output creates accordingly. Global variables are variables that can be accessed and manipulated anywhere in the program. An endless loop can mean two things. Further float, double and long double data types do not have this property. There is no single command or function in C that can check if a number is odd or even.
