4862Single character input output, String input and output, Formatted Input For Scanfhttp://www.exforsys.com/content/view/1987/364/One of the essential operations performed in a C language programs is to provide input values to the program and output the data produced by the program to a standard output device. We can assign values to variable through assignment statements such as x = 5 a = 0 ; and so on. AnotherC and C++ > Tips and Tutorials > Programming in C and C++Oct 10, 2006Exforsys
A unique feature of c language is the preprocessor. A program can use the tools provided by preprocessor to make his program easy to read, modify, portable and more efficient.
During looping a set of statements are executed until some conditions for termination of the loop is encountered. A program loop therefore consists of two segments one known as body of the loop and other is the control statement. The control statement tests certain conditions and then directs the repeated execution of the statements contained in the body of the loop
C permits nesting of two functions freely. There is no limit how deeply functions can be nested. Suppose a function a can call function b and function b can call function c and so on. Consider the following program:
Function groups a number of program statements into a unit and gives it a name. This unit can be invoked from other parts of a program. A computer program cannot handle all the tasks by it self. Instead its requests other program like entities - called functions in C - to get its tasks done. A function is a self contained block of statements that perform a coherent task of same kind
