Example:

#include 
      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;
}
output 1
