Hello Programmers, In this post, you will know how to solve the Basic Data Types in C++ HackerRank Solution. This problem is a part of the HackerRank C++ Programming Series.
One more thing to add, don’t directly look for the solutions, first try to solve the problems of Hackerrank by yourself. If you find any difficulty after trying several times, then you can look for solutions.
Basic Data Types in C++ HackerRank 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 14049.304930000
Explanation :
Print int 3.
followed by long 12345678912345.
followed by char a.
followed by float 334.230.
followed by double 14049.304930000.
