   1. Basic Data Types
   
   

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.

---

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

Solution  C++ :

#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;

}
