Write a C program "if...else" statement

 Write a C program to check whether a number entered by user is even or odd

#include <stdio.h>
int main(){
      int num;
      printf("Enter a number you want to check.\n");
      scanf("%d",&num);
      if((num%2)==0)          //checking whether remainder is 0 or not.
           printf("%d is even.",num);
      else
           printf("%d is odd.",num);
      return 0;
}

Write a C program " if statement"

Write a C program to print the number entered by user only if the number entered is negative.


#include <stdio.h>
      int main(){
      int num;
      printf("Enter a number to check.\n");
      scanf("%d",&num);
      if(num<0) {      /* checking whether number is less than 0 or not. */ 
            printf("Number = %d\n",num); 
      }  
/*If test condition is true, statement above will be executed, otherwise it will not be executed */
      printf("The if statement in C programming is easy.");
return 0;
}
