C++ Datatypes - Hackerrank

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

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

int main() {
    // Complete the code.
    int a;
    long b;
    char c;
    float d;
    double e;

    cin>>a>>b>>c>>d>>e;

    printf("%d\n%ld\n%c\n%f\n%lf\n",a,b,c,d,e);

    return 0;
