Today we make a Program about how to display data type size using c++.it is very easy to make it.Now we start to make it.
Display Data Type of int, float, double and char
Showing the size of data types C++ code
#include <iostream>
#include <stdlib.h>
using namespace std;
int main()
{
cout<<"The size of an int is:\t\t"<<sizeof(int)<<" bytes.\n";
cout<<"The size of a short int is:\t"<<sizeof(short)<<" bytes.\n";
cout<<"The size of a long int is:\t"<<sizeof(long)<<" bytes.\n";
cout<<"The size of a char is:\t\t"<<sizeof(char)<<" bytes.\n";
cout<<"The size of a float is:\t\t"<<sizeof(float)<<" bytes.\n";
cout<<"The size of a double is:\t"<<sizeof(double)<<" bytes.\n";
cout<<"The size of a bool is:\t\t"<<sizeof(bool)<<" bytes.\n";
system("pause");
return 0;
}Output of Program
Size of char: 1 byte Size of int: 4 bytes Size of float: 4 bytes Size of double: 8 bytes
