Thread: Help pleaasee!!

Can someone help me out its a homework. I wrote the program just stuck.


1)Write a program that will ask the user to enter a number. Then createa loop of your choice that will multiply the number by itself thenumber of times equal to the number itself. Like the power functionin math x raised to the y power. Do this with a loop, not the mathpower function.


my program

Code:

Code:

#include <stdio.h>


int main()


{
int a; 
int x;


printf("Enter a Number\n");
fflush(stdin);
scanf("%d", & a);


for (int i=0; i<=x; i++)
    a= a*a;
  {
      printf("The result is %d \n",a);
  }  
  
}

which ever number i pick the program its suppose to multiply it that many times so if i pick 3 its gonna do 3x3x3

my program i wrote whats to multiply any number i put in to the 4th power. can someone help me out and guide me the right way please and thank you.

I think you're missing one line; put x = a; before the loop.

If i add x= a; any number i put in it will give me a 0

fflush has nothing to do with the loop not working. but thank you.

Hey whiteflags do you have a personal email address. If you could answer some simply questions from me if you don't mind about programing i don't get any of this . thank you.

Please post on the forum if you want to talk to me.

Code:

#include <stdio.h>      
main ( )
{
    int i, num[6];
    int oddNumbers = 0,evenNumbers = 0;
    for(i=0; i<=5; i++)     
    {
    printf("Enter a number betweem -20 and + 20 \n");
    fflush(stdin);
    scanf("%d",&num[i]);
    if (num [i] <-20 || num [i] > 20  )      
    {
    printf("number you entere outside the limits");
    i=i -1;}
     }  
     printf("\n Even numbers are:\n");
        for (i=0;i< 6; i++)     
    {
       if (num[i] % 2 == 0)
               {
                   printf("%d\n",num[i]);
               {
                   else                   CAN YOU TELL ME WHY THIS ELSE STAMENT IS NOT WORKING and giving me the odd numbers i can get it to do evens
{
                       printf("\n Odd Numbers are:\n")
                   }
               //  printf("\n Odd Numbers are:\n");
               }    
      //    else  
           // this else statement is not working what am i missing for it to print the  
         //  printf("%d\n",num[i]);        
               }    
                   
           }
       //    printf("\n Odd Numbers are:\n");
           //        for (i=0; i< num; i_++)    
               {
                   //if (num[i]% 2 !=0)
                   {
                   //    printf("%d\n",num[i]);
                   }
                     
            
   }
}

You're basically asking if he's a total loser. That's incredibly rude.

And why should anyone help you since you don't take the advice anyway? You were told not to use fflush on stdin and you basically told the person to f off and you are still using it.

And you don't give your posts a proper title ("help!!!" is not a useful title).
And you don't bother to properly space your code.
And you post it with a bunch of commented out crap.

You're lucky that anyone bothers to help you at all.

Well thanks for being an ass algorism and i've been using fflush to clear the buffer. Thats what they teached in class so . It's an intro to c++ have a junk basic platform program i'm using. I guess i could of taken the comments out but no reason to be a total db. Forums are meant to help people learn not to bash but thank you .

"i've been using fflush to clear the buffer. Thats what they teached in class so."

Unfortunately, there are many so-called instructors teaching C very badly.

The use of "fflush(stdin)" is wrong. fflush() is for output buffers only. The code that @whiteflags & the link that @salem gave you shows you is the correct way of flushing any input buffer, stdin, stdin redirected from a file, or a disk file opened for input.

Code:

while ((c = getchar()) != '\n' && c != EOF)
