CPP program to display basic data type values

In this article we will learn to implement a CPP program to display basic data type values. A C++ program is provided below to print the basic data type values.

This is a C++ program to read and print basic data type values. The float type value must be corrected to 3 places and double type value must be corrected to 9 decimal places. To make this happen, we used fixed and setprecision available in iomanip header file. Code is as follows:

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

int main() {
    int a;
    long int b;
    long long int c;
    char d;
    float e;
    double f;
    cin>>a>>b>>c>>d>>e>>f;
    cout<<a<<endl<<b<<endl<<c<<endl<<d<<endl;
    cout<<fixed<<setprecision(3)<<e<<endl;
    cout<<fxed<<setprecision(9)<<f;
    return 0;
}

Input and output for the above program are as follows:

Input:
3 444 12345678912345 a 334.23 14049.30493

Output:
3
444
12345678912345
a
334.230
14049.304930000
