Basic Data Types Cpp - Hackerrank Solution

 

Basic Data Types in C++

---

Objective:

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.

Solution:

#include <iostream> #include <cstdio> using namespace std; int main() {     int a;     cin>>a;     cout<<a<<endl;     long int b;     cin>>b;     cout<<b<<endl;     char c;     cin>>c;     cout<<c<<endl;     float v;     scanf("%f",&v);     printf("%f\n",v);     double r;     scanf("%lf",&r);     printf("%lf\n",r); }
