Syntax<\/strong><\/p>\n int number1;<\/em> Type conversion<\/strong> is a concept in which one type of data is automatically converted into another type without the programmer\u2019s involvement<\/em>. It is solely done by the compiler only if both the data types are compatible with each other.<\/em><\/p>\n Syntax<\/strong><\/p>\n int number1 = 5;<\/em> Often people tend to use the terms typecasting and type conversions interchangeably whenever we talk about the conversion of one type of data to another, like, from int to char.<\/p>\n It is important to note the following key differences:<\/p>\n In the C\/C++ programming language, type conversions are of two types, namely:<\/p>\n It is automatic in nature as the compiler itself converts the variable from one type to the other without the employment of any other function. Hence, we do not require any operator.<\/p>\n It is important to understand the rules associated with implicit type conversions. They are:<\/p>\n For instance, consider the following segment of code:<\/p>\n Now, let us understand how this works:<\/p>\n In implicit type conversion, the \u201cx\u201d in a \/ x is automatically converted into the bigger data type, that is, the float data type. This happens in order to make \u201cx\u201d equal to \u201ca\u201d in terms of its data type.<\/p>\n Therefore, the value of x = 4.0 and the expression a \/ x would be 14.4 \/ 4.0 = 3.6<\/p>\n Note that the value of the char data type would be treated as its ASCII value, not as its original character type when an operation is performed between the char and int data type.<\/p>\n For instance, consider the following segment of code:<\/p>\n Now, let us understand how it works:<\/p>\n We know that the ASCII value of the lowercase character \u2018z\u2019 is 122. Therefore, the compiler automatically converts the character of char data type into the integer data type and the expression sum = character + number becomes equal to 122 + 8 = 130 From this discussion, it is pretty clear that the lower data type is converted into a higher data type.<\/p>\n The following diagram illustrates the ranking of a lower data type to a higher data type:<\/strong><\/p>\n It is done by the programmer according to his own convenience with the help of the cast operator.<\/p>\n Key takeaway:<\/strong> The new data type should clearly be mentioned either before the identifier or the value within brackets that are to be typecasted.<\/em><\/p>\n Here is a program that illustrates the use of typecasting in C language:<\/p>\n <\/p>\n
