Basic Data Types in C++ - Hacker Rank Solutions

Hey Coders, Today we will learn about some basic Data Types of C++ and how to use them in our program to get the desire output.

We will be solving on of the Hackerrank problem (Basic Data Types in C++) which will describe us what basically data types are and how to implement them in our code.

So, Without further ado let's jump into the problem.

• 7 Conclusion

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
14049.304930000

Explanation

Print Int 3.

followed by long 12345678912345,

followed by char a, 

followed by float 334.23,

followed by double 14049.30493.

Solution - Basic Data Types in C++

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

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

    scanf("%d %ld %c %f %lf", &a, &b, &c, &d, &e);
    printf("%d\n%ld\n%c\n%f\n%lf", a, b,c, d, e);
    return 0;
}
