C Programming: Prints all even numbers between 1 and 50

C Code:

#include <stdio.h>

int main() {
	int i;
	printf("Even numbers between 1 to 50 (inclusive):\n");
	for (i = 1; i <= 50; i++) 
	{
		if(i%2 == 0) 
		{
		  printf("%d ", i);
		}
	}
	return 0;
}

Sample Output:

Even numbers between 1 to 50 (inclusive):                              
2 4 6 8 10 12 14 16 18 20 22 24 26 28 30 32 34 36 38 40 42 44 46 48 50

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().
