Introduction To C++

C++ is a general-purpose programming language that was developed as an enhancement of the C language to include object-oriented paradigm. It is an imperative and a compiled language. 

C++ is a middle-level language rendering it the advantage of programming low-level (drivers, kernels) and even higher-level applications (games, GUI, desktop apps etc.). The basic syntax and code structure of both C and C++ are the same. 

C++ programming language was developed in 1980 by Bjarne Stroustrup at bell laboratories of AT&T (American Telephone & Telegraph), located in U.S.A. Bjarne Stroustrup is known as the founder of C++ language.

Basic Data Types in C++ Solution

Problem

Some C++ data types, their format specifiers, and their most common bit widths are as follows:

  • Int (“%d”): 32 Bit integer
  • Long (“%ld”): 64 bit integer
  • Char (“%c”): Character type
  • Float (“%f”): 32 bit real value
  • Double (“%lf”): 64 bit real value

Reading

To 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.

Printing

To 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 Format

Input consists of the following space-separated values: int, long, char, float, and double, respectively.

Output Format

Print 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 Input :

3 12345678912345 a 334.23 14049.30493

Sample Output :

3
12345678912345
a
334.230
14049.304930000

Explanation :

Print int 3.
followed by long 12345678912345.
followed by char a.
followed by float 334.230.
followed by double 14049.304930000.

    Each online casino that we reviewed is required to have customer support, so that you can get answers to your questions. Most online casinos provide good and instant customer support, but again, this all depends on your chosen online casino. One dollar deposit casinos often offer you an impressive number of free spins for $1 in Canada. You sometimes receive 100+ free spins by depositing a single dollar. 100 free spins for $1 are more than enough to help you get started at online casinos. With the free spins, you can try different slot games and win real money without spending your own cash. However, you must follow free spins terms and conditions if you want to make the most out of them. For example, you need to use your free spins on the specified games and fulfil wagering requirements within the specified timeframe to be able to withdraw your winnings.
