scanf() is a predefined function in______header file.*1 pointstdlib. hctype. hstdio. hdstdarg. h

Marks the statements below about header files, as True/False.Read the spellings carefullyTrue False The stdio.h contains#ifndef _STDIO_H#define _STDIO_H    1as the first two lines,It is done to prevent  multiple inclusions of the same header files. #include <stdio.h>means copy paste the header file stdio.h in the place of the above line It's a common practice to move code of some of the functions to header files, and then #include those files, whenever needed. stdio.h contains the code for scanf(), printf() and getchar(). #include "my.h"means copy the file my.h from /usr/include, and paste it in the program, in place of the above line. The typical location for header files on Linuxes is /user/includes/headers/ Header files typically contain pre-processor directives, typedefs, and function prototypes only

To scan a and b given below, which of the following scanf() statement will you use?#include<stdio.h>float a;

Which of the following function used as reading data ?Options :main()print()scanf()printf()

The fundamental data types in c are int, float and char. Today, we're discussing int and float data types.The printf() function prints the given statement to the console. The syntax is printf("format string",argument_list);. In the function, if we are using an integer, character, string or float as argument, then in the format string we have to write %d (integer), %c (character), %s (string), %f (float) respectively.The scanf() function reads the input data from the console. The syntax is scanf("format string",argument_list);. For ex: The scanf("%d",&number) statement reads integer number from the console and stores the given value in variable .To input two integers separated by a space on a single line, the command is scanf("%d %d", &n, &m), where and are the two integers.TaskYour task is to take two numbers of int data type, two numbers of float data type as input and output their sum:Declare variables: two of type int and two of type float.Read lines of input from stdin (according to the sequence given in the 'Input Format' section below) and initialize your variables.Use the and operator to perform the following operations:Print the sum and difference of two int variable on a new line.Print the sum and difference of two float variable rounded to one decimal place on a new line.Input FormatThe first line contains two integers.The second line contains two floating point numbers.Constraints integer variables float variables Output FormatPrint the sum and difference of both integers separated by a space on the first line, and the sum and difference of both float (scaled to decimal place) separated by a space on the second line.Sample Input10 44.0 2.0Sample Output14 66.0 2.0ExplanationWhen we sum the integers and , we get the integer . When we subtract the second number from the first number , we get as their difference.When we sum the floating-point numbers and , we get . When we subtract the second number from the first number , we get as their difference.
