# HackerRank Basic Data Types solution in c++ programming

In this HackerRank Basic Data Types problem solution in the c++ programming language, 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);

## HackerRank Basic Data Types problem solution in c++ programming.

```#include<bits/stdc++.h>
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<<fixed<<setprecision(3)<<d<<"\n";
cout<<fixed<<setprecision(9)<<e<<"\n";
return 0;
}```

## Second 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;
}```

### Third solution

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

int main() {
// Complete the code.
int i;
long l;
char c;
float f;
double d;
scanf("%d %ld %c %f %lf" , &i, &l, &c, &f, &d);
printf("%d\n%ld\n%c\n%.3f\n%.9lf\n", i,l,c,f,d);

return 0;
}```
