Question

Name the type of conversion shown in the following snippet. Also mention the output datatype . int a ; short b ; float c; long d; x = ( a + b )*(c + d); which type of conversion is shown​

Answer 1

Answer:

What is Typecasting in C?

Typecasting is converting one data type into another one. It is also called as data conversion or type conversion in C language. It is one of the important concepts introduced in ‘C’ programming.

‘C’ programming provides two types of type casting operations:

Implicit type casting

Explicit type casting

Implicit type casting

Implicit type casting means conversion of data types without losing its original meaning. This type of typecasting is essential when you want to change data types without changing the significance of the values stored inside the variable.

Implicit type conversion in C happens automatically when a value is copied to its compatible data type. During conversion, strict rules for type conversion are applied. If the operands are of two different data types, then an operand having lower data type is automatically converted into a higher data type. This type of type conversion can be seen in the following example.

#include<stdio.h>

int main(){

short a=10; //initializing variable of short data type

int b; //declaring int variable

b=a; //implicit type casting

printf("%d\n",a);

printf("%d\n",b);

}

Output:

10

10

Implicit type casting example

In the given example, we have declared a variable of short data type with value initialized as 10.

On the second line, we have declared a variable of an int data type.

On the third line, we have assigned the value of variable s to the variable a. On third line implicit type conversion is performed as the value from variable s which is of short data type is copied into the variable a which is of an int data type.
