C Exercises: Demonstrates the difference between predecrementing and postdecrementing using the decrement operator
C Basic Declarations and Expressions: Exercise-78 with Solution
Write a C program to demonstrates the difference between predecrementing and postdecrementing using the decrement operator --.
Sample Solution:
C Code:
#include<stdio.h>
int main()
{
int x = 10;
printf("Predecrementing:\n");
printf("x = %d\n", x);
printf("x-- = %d\n", x--);
printf("x = %d\n\n", x);
x = 10;
printf("Postdecrementing:\n");
printf(" x = %d\n", x);
printf("--x = %d\n", --x);
printf(" x = %d\n", x);
return 0;
}
Sample Output:
Predecrementing: x = 10 x-- = 10 x = 9

C Programming: Tips of the Day
Static variable inside of a function in C
The scope of variable is where the variable name can be seen. Here, x is visible only inside function foo().
The lifetime of a variable is the period over which it exists. If x were defined without the keyword static, the lifetime would be from the entry into foo() to the return from foo(); so it would be re-initialized to 5 on every call.
The keyword static acts to extend the lifetime of a variable to the lifetime of the programme; e.g. initialization occurs once and once only and then the variable retains its value - whatever it has come to be - over all future calls to foo().
