# Basic Data Types – HackerRank 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

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: intlongcharfloat, 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 `334.23`,
followed by double `14049.30493`.

## Solution :

``````#include <iostream>
#include <cstdio>
#include <iomanip>
using namespace std;

int main() {

int a;
long b;
char c;
float d;
double e;
cin >> a >> b >> c >> d >> e;
cout<< a << '\n' << b << '\n' << c << '\n';
cout << std::fixed << std::setprecision(3) << d << '\n';
cout << std::fixed << std::setprecision(9) << e << '\n';

return 0;
}``````
