Type Conversion In C Language

A type cast is basically a conversion from one type to another. There are two types of type conversion:

1.Implicit Type Conversion

2.Explicit Type conversion

Advantages of Type Conversion

·     This is done to take advantage of certain features of type hierarchies or type representations.

·         It helps us to compute expressions containing variables of different data types.

1.Implicit Type Conversion

All the data types of the variables are upgraded to the data type of the variable with largest data type.

Fig:Implicit Type conversion 

Program

#include<stdio.h>

int main()

{

          int x = 10; // integer x

          char y = 'a'; // character c

          // y implicitly converted to int. ASCII

          // value of 'a' is 97

          x = x + y;

         

          // x is implicitly converted to float

          float z = x + 1.0;

          printf("x = %d, z = %f", x, z);

          return 0;

}

Output:

x=107 z=108.0000

2.Explicit Type Conversion

This process is also called type casting and it is user defined. Here the user can type cast the result to make it of a particular data type.

The syntax in C:

(type) expression

Program:

#include<stdio.h>

int main()

{

          double x = 1.2;

          // Explicit conversion from double to int

          int sum = (int)x + 1;

          printf("sum = %d", sum);

          return 0;

}

Output:

Sum=2
