C Exercises: Check whether a given integer is positive even, negative even, positive odd or negative odd
C Basic Declarations and Expressions: Exercise-31 with Solution
Write a C program to check whether a given integer is positive even, negative even, positive odd or negative odd. Print even if the number is 0.
Pictorial Prresentation:
C Code:
#include <stdio.h>
int main() {
int x;
printf("Input an integer: ");
scanf("%d", &x);
if(x == 0){
printf("Positive\n");
}
else if(x < 0 && (x%2) != 0)
{
printf("Negative Odd\n");
}
else if(x < 0 && (x%2) == 0)
{
printf("Negative Even\n");
}
else if(x > 0 && (x%2) != 0)
{
printf("Positive Odd\n");
}
else if(x > 0 && (x%2) == 0)
{
printf("Positive Even\n");
}
return 0;
}
Sample Output:
Input an integer: 13 Positive Odd

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().
