Printf() Function in C Hindi/Urdu| Example Code 2.1 | Activity 2.1 & 2.2 | 10th Computer Chapter 2

Unit Introduction: A computer is a device that takes- data as input, processes that data and generates the output. Thus all the programming languages must provide instructions to handle input, output and processing of data. In this chapter, we discuss different pre-built input/output functions available in C language. Weal so discuss different operators that we can apply to process the data. 2.1 Input/output (I/O) functions: We need a way to provide input and show output while writing programs. Each programming language has its keywords or standard library functions for me /Operations. C language offers printf function to display the output, and scan function to get input from user. In the following section, we discuss these two functions 2.1.1 printf () printf is a built-in function in C programming language to show output onscreen. Its name comes from "print formatted" that is used to print the formatted output on screen. All data types discussed in the previous chapter can be displayed with printf function. To understand the working of printf function, let’s look at the following example program:   Example Code 2.1 Activity 2.1 Activity 2.2 Write a program that shows your first name is Uppercase and your last name in lower case letters on screen.
