/* Write a program that can take 2 float and 1 character values as input. Define four functions add, sub, mult and div for addition, subtraction, multiplication and division respectively. Define a procedure by using switch statement in which the functions are called by analyzing the character input i.e. '+' for addition, '-'for subtraction, '*' for multiplication and '/' for division. The functions will then return the result for printing to the main function. */

Q3.  

·         Scanf() and gets()

The scanf() function, reads input for numbers and other datatypes from  standard input.

 The gets() function reads characters from stdin and stores them as a string into str until a newline character ('\n') or the End-of-File is reached. The ending newline character ('\n') is not included in the string. A null character ('\0') is automatically appended after the last character copied to str to signal the end of the C string.

·         Printf() and puts()

The printf() function writes to the standard output. Printf() could be thought of as a more powerful version of puts(). `printf' provides the ability to format  variables for output using format specifiers such as %s, %d, %lf, etc...

The puts() function only permits  you to  print single string on the output screen.





·         Break and continue



The continue statement provides a convenient way to force an immediate jump to the loop control statement. The break statement terminates the execution of the loop.





·         Function definition and function declaration



The prototype statement for a function declares it, i.e, tells the compiler about the function name, return type, and number and type of its parameters.

The function header, followed by the body of the function, defines the function giving the details of the steps to perform the function operation.
