The typedef declaration
creates a synonym for the existing type. We use the typedef to create an alias name for the existing type name. The usage is of the following syntax:
typedef some_type our_new_name;
To create a new synonym for the type int and, for example, call it MyInteger, we type:
typedef int MyInteger;
Now, we can use the new MyInteger
alias in the same way we would use int. Example:
#include <stdio.h>
typedef int MyInt;
int main(void)
{
MyInt x = 123;
printf("The value is: %d\n", x);
}
Output:
The value is: 123
We can also create an alias for a pointer type:
#include <stdio.h> ...
