Part 1: For this assignment, call it assign0 Implement the following library and driver program under assign0: Your library will be consisting of myio.h and myio.c. The function prototypes as well as more explanations are listed in myio.h. Please download it and accordingly implement the exported functions in myio.c. Basically, you are asked to develop a simple I/O library which exports a few functions to simplify the reading of an integer, a double, and more importantly a string (whole line). In contrast to standard I/O functions that can read strings (e.g., scanf with \"%s\", fgets) into a given static size buffer, your function should read the given input line of characters terminated by a newline character into a dynamically allocated and resized buffer based on the length of the given input line. Also your functions should check for possible errors (e.g., not an integer, not a double, illigal input, no memory etc.) and appropriately handle them. Then write a driver program driver.c that can simply use the functions from myio library. Specifically, your driver program should get four command-line arguments: x y z output_filename. It then prompts/reads x many integers, y many doubles, and z many lines, and prints them into a file called output_filename.txt. Possible errors should be printed on stderr.

Simple C program to obtain the integer, string and float values.

#include <stdio.h> // #include is a preprocessor directive to paste the code from the header file when necessary

# include <myio.h> // After creating the myio.c program we can call the function in header

int main()

{

char ch, int testinteger, float f, double lf; // Declaring the program

char str[100];

printf(“Enter the integer:\ ”);

scanf(\"%d\", & testInteger);

printf(“ Number = %d “, testinteger \ );

printf(“Enter the float value:”\ );

scanf(\"%f\", & f);

printf(“ Value = %f “, f\ ); // %f format string is used in case of floats

printf(\" Enter the Double value is %lf \ \", dbl);

scanf(\"%lf\", & dbl);

printf(“ Value =%lf”, dbl \ );

printf(\"Enter any character \ \"); // Format string %c is used in case of character types.

scanf(\"%c\", &ch);

printf(\"Entered character is %c \ \", ch);

printf(\"Enter any string ( upto 100 character ) \ \");

scanf(\"%s\", &str \ );

printf(\"Entered string is %s \ \", str);

Explanation of some important concepts.

printf() and scanf() functions are inbuilt library functions in C programming language which are available in C library by default. These functions are declared and related macros are defined in “stdio.h” which is a header file in C language.

PRINTF() FUNCTION IN C LANGUAGE:

In C programming language, printf() function is used to print the “character, string, float, integer, octal and hexadecimal values” onto the output screen.

We use printf() function with %d format specifier to display the value of an integer variable.

To generate a newline,we use “\ ” in C printf() statement.

SCANF() FUNCTION IN C LANGUAGE:

In C programming language, scanf() function is used to read character, string, numeric data from keyboard

Consider below example program where user enters a character. This value is assigned to the variable “ch” and then displayed.

Then, user enters a string and this value is assigned to the variable “str” and then displayed
