About this program
This is an example program in c calculation programs. Read the concept first: Data Types in C Programming, then study the code and output below.
Definition
A formal definition of an even number is that it is an integer of the form n = 2k, where k is an integer;[3] it can then be shown that an odd number is an integer of the form n = 2k + 1.
Odd Or Even Example Program Using Functions
/*##Check if an integer is odd or even*/
/*##Calculation Programs, Datatype Programs, Basic Programs*/
#include <stdio.h>
char* odd_even(int i);
int main()
{
int number;
printf("Enter an integer : ");
scanf("%d", &number);
printf("Result : %s",odd_even(number));
return 0;
}
char* odd_even(int number)
{
if (number%2 == 0){
return "YOUR NUMBER IS EVEN NUMBER";
}else{
return "YOUR NUMBER IS ODD NUMBER";
}
}Sample Output
Enter an integer : 5
YOUR NUMBER IS ODD NUMBER
Enter an integer : 6
YOUR NUMBER IS EVEN NUMBERRelated Pages
