Type conversion in compiler design refers to the process of converting a data object of one type to another type. This operation is essential for ensuring that operations involving different data types are performed correctly and efficiently. There are two main types of type conversions: implicit and explicit.
Implicit Type Conversion
Implicit type conversion, also known as coercion, is an automatic conversion performed by the compiler without any explicit instruction from the programmer. This type of conversion typically occurs in mixed-mode expressions where operands of different types are involved. For example, in Pascal, if one operand is an integer and the other is a real number, the integer is implicitly converted to a real number before the operation is performed2.
Example of Implicit Type Conversion in C
#include <stdio.h>int main() {int x = 10;char y = 'a';x = x + y;float z = x + 1.0;printf("x = %d, z = %f", x, z);return 0;}Output:
x = 107, z = 108.000000 What is Type Conversion? - Online Tutorials Library

Type Checking in Compiler Design - GeeksforGeeks
- Type checking is the process of verifying that the types of all variables, expressions, and functions are according to the rules of the programming language. It means operations operate on compatible data types, which helps in preventing errors and hence ensures correctness of the program. Type checking might be performed at compile time, called st...
Type conversion - Wikipedia
In computer science, type conversion, type casting, type coercion, and type juggling are different ways of changing an expression from one data type to another. An example would be the conversion of an integer value into a floating point value or its textual representation as a string, and vice versa. Type conversions can take advantage of certain features of type hierarchies or data representations. Two important aspects of a type conversion are whether it happens implicitly (…
