Basic Data Types HackerRank 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
14049.304930000Explanation :

Print int 3.

followed by long 12345678912345.

followed by char a.

followed by float 334.230.

followed by double 14049.304930000.

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

int main() 
{
 int a;
 long long int b;
 char c;
 float d;
 double e;

 scanf("%d %lld %c %f %lf",&a,&b,&c,&d,&e);

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

return 0;
