Smart Grids and Energy Storage Systems: Powering the Future of Energy In today’s rapidly evolving energy landscape, the push towards sustainability, efficiency, and reliability is stronger than ever. Traditional power grids, though robust in their time, are no longer sufficient to meet the demands of a modern, digital, and environmentally conscious society. This is where smart grids and energy storage systems (ESS) come into play — revolutionizing how electricity is generated, distributed, and consumed. What is a Smart Grid? A smart grid is an advanced electrical network that uses digital communication, automation, and real-time monitoring to optimize the production, delivery, and consumption of electricity. Unlike conventional grids, which operate in a one-way flow (from generation to end-user), smart grids enable a two-way flow of information and energy. Key Features of Smart Grids: Real-time monitoring of power usage and quality. Automated fault detection and rapid restoration. Int...
TYPE CONVERSION AND TYPECASTING
Type conversion or typecasting of variables refers to converting a variable of one data type into another. While type conversion is done implicitly, casting has to be finish explicitly by the programmer.
We will discuss both these concepts here.
Type Conversion
Type conversion is finish when the expression has variables of different data types. So to calculate the expression, the data type is upgrade from lower to higher level where the hierarchy of data types can be given as: double, float, long, int, short, and char. For example, type conversion
is automatically done when we assign an integer value to a floating point variable. Consider the following code:
float x;
int y = 3;
x = y;
Now, x = 3.0, as integer value is automatically converted into its same floating point representation.
Typecasting
Typecasting is also known as forced conversion. It is complete when the value of one data type has to be converted into the value of another data type. The code to perform typecasting can be given as:
float salary = 10000.00;
int sal;
sal = (int) salary;
When floating point numbers are converted to integers, the digits after the decimal are truncated. Therefore, data is lost when floating point representations are converted to integral representations.
As we can see in the code, typecasting can be done by placing the destination data type in parentheses followed by the variable name that has to be converted. Hence, we conclude that typecasting is done to make a variable of one data type to act like a variable of another type.
Programming Example
Write a program to convert an integer into the corresponding floating point number.
#include <stdio.h>
#include <conio.h>
int main()
{
float f_num;
int i_num;
clrscr();
printf("\n Enter any integer: ");
scanf("%d", &i_num);
f_num = (float)i_num;
printf("\n The floating point variant of %d is = %f", i_num, f_num);
return 0;
}
Output
Enter any integer: 56
The floating point variant of 56 is = 56.000000
