What is a type cast in C?

• Type casting is used to make a variable of one type behave like another. For instance, character values in C can be type cast. Ex: int num = (char) 'c'; This declaration would store the equalent int of the char in num. Type casts are most useful when passing structs to functions that accept void* as an argument.

What is casting in C?

The compiler will automatically change one type of data into another if it makes sense. For instance, if you assign an integer value to a floating-point variable, the compiler will insert code to convert the int to a float.

What is type casting in C programming?

How to typecast in C?

• Typecasting in C. By Alex Allain. Typecasting is a way to make a variable of one type, such as an int, act like another type, such as a char, for one single operation.
