In C, a double data type is used to increase the accuracy of the real number wherever a float is not sufficient.A double data type occupies 8 bytes (64 bits) of memory to store real numbers, which have atleast one digit after the decimal point.A double data type can hold any value between 1.7E-308 to 1.7E+308.double data type values have a precision of 14 digits i.e., they can have 14 digits after the decimal point.Consider the following example using a double data type.#include <stdio.h>void main() { double num1 = 26.7368; double num2 = 1.42924; double total; total = num1 + num2; printf("Total of the given two numbers = %f\n", total);}Here, 8 bytes of memory is allocated to each variable num1, num2 and they are initialized with real number constants 26.7368 and 1.42924 respectively.Click on Live Demo to know about double data type in C.To further extend the precision of a double data type, the user can use long double data type. The long double type is guaranteed to have more bits than a double, while the exact number may vary from one hardware platform to another.A long double data type allocates 10 bytes(80 bits) of memory to store the given values.A long double data type can hold any value between 3.4E-4932 to 1.1E+4932.Select all the correct statements from the given statements.A double data type occupies 8 bytes of memory.A double data type can have up to 10 decimal places for the fractional part.A long double data type allocates 16 bytes of memory to the variables.A double data type uses 1 bit for sign, 10 bits for exponent value and 53 bits for mantissa part.

Some C++ data types, their format specifiers, and their most common bit widths are as follows:Int ("%d"): 32 Bit integerLong ("%ld"): 64 bit integerChar ("%c"): Character typeFloat ("%f"): 32 bit real valueDouble ("%lf"): 64 bit real valueReadingTo read a data type, use the following syntax:scanf("`format_specifier`", &val)For example, to read a character followed by a double:char ch;double d;scanf("%c %lf", &ch, &d);For the moment, we can ignore the spacing between format specifiers.PrintingTo print a data type, use the following syntax:printf("`format_specifier`", val)For example, to print a character followed by a double:char ch = 'd';double d = 234.432;printf("%c %lf", ch, d);Note: You can also use cin and cout instead of scanf and printf; however, if you are taking a million numbers as input and printing a million lines, it is faster to use scanf and printf.Input FormatInput consists of the following space-separated values: int, long, char, float, and double, respectively.Output FormatPrint each element on a new line in the same order it was received as input. Note that the floating point value should be correct up to 3 decimal places and the double to 9 decimal places.Sample Input3 12345678912345 a 334.23 14049.30493Sample Output312345678912345a334.23014049.304930000

What will be the data type returned for the following C function? #include <stdio.h> int func() { return (double)(char)5.0; }
