HACKERRANK C++ BASIC DATA TYPES

SOLUTION-

Input and Output it's easier to take input using cin and cout or you could still use printf and scanf. Now the tricky part is while trying to print the floating and double values. You need to use setprecision() which is available in the iomanip library. 

 #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;
}

#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;
}
