transforming code to one main function..

i got this working code
where i built functions and called them
how to transform this code into one main function??
i tried it didnt give me the output i got before
??

Code:

#include<stdio.h>



int is_abundant(int tndex) {
int jndex,sum;
int flag_1;
flag_1=0;
sum=0;
for(jndex=1;jndex<tndex;jndex++){//start abbondence check for first num (tndex)
                        if (tndex&#37;jndex==0){
                            sum=sum+jndex;
                        }
                        if (tndex<sum){
                        flag_1=1;
                    }

                    }//end abbondence check for first num

 return flag_1;
}

void print_if_sum_of_abundants(int n) { 
 int i;
	for( i=1;i*2<=n;++i) {
		if(is_abundant(i)&&is_abundant(n-i)) { 

			printf("%d=%d+%d\n",n,i,(n-i));
              i=n+1;

} 
  } 
} 

int main() { 
  int limit;
int i;
printf("enter number:");
   scanf("%d",&limit);
  
  
  for(i=1;i<=limit;++i) {
    print_if_sum_of_abundants(i); 
  }
  return 0;
}

know i need to transform all of my program into one "main" function code
i tried to do that but it gives me a very bad output

Code:

#include<stdio.h>





int main() { 
    int index;  
	int limit,i;
	int flag_1=0;
	int flag_2=0;
	int jndex,sum;
int number;
printf("enter number:");
   scanf("%d",&limit);
  
  
  for(number=0;number<=limit;++number) {/////////////////////////////////// start main for
    
	for( index=1;index*2<=number;++index) {



///////////////////////////////////////////////////////////abondence check 1



sum=0;
for(jndex=1;jndex<index;jndex++){//start abbondence check for first num (tndex)
                        if (index%jndex==0){
                            sum=sum+jndex;
                        }
                        if (index<sum){
                        flag_1=1;
                    }

                    }//end abbondence check for first num
		/////////////////////////////////////////////////end abondence check 1


///////////////////////////////////////////////////////////abondence check 2



sum=0;
for(jndex=1;jndex<(number-index);jndex++){//start abbondence check for first num (tndex)
                        if ((number-index)%jndex==0){
                            sum=sum+jndex;
                        }
                        if ((number-index)<sum){
                        flag_2=1;
                    }

                    }//end abbondence check for first num
		/////////////////////////////////////////////////end abondence check 2







		if((flag_1==1)&&(flag_2==1)) { 

			printf("%d=%d+%d\n",number,index,(number-index));
              index=number+1;
			  flag_1=0;
			  flag_2=0;

} 
  }

  } ///////////////////////////////////////////////end main for
  return 0;
}

Kinda hoping that you'll learn how to indent code at some point.
It's a long wait....

Why would you want to have just one main function?

Because my prof didnt allow us to use matirial that he didnt teach.

So i need to give one main function.

I tried to substitute (like i showed ) but i get a very bad output.
??

Grr... stop trying to "reverse engineer" without understanding the code!

And as Salem noted, indent your code properly.

I will try.
how to order the code properly?

i try to keep each open and close cols parralell

The rule of thumb is: whenever the code enters into a block, indent the code by one level, and keep the levels consistent. When the code leaves the block, decrease the indentation by one level.

Also, most of the time there is no point in leaving more than one blank line to separate code, (and for those exceptions, two blank lines will do).

Your first code sample would be much easier to read when indented properly, e.g.,

Code:

#include<stdio.h>

int is_abundant(int tndex) {
    int jndex,sum;
    int flag_1;
    flag_1=0;
    sum=0;
    for(jndex=1;jndex<tndex;jndex++){//start abbondence check for first num (tndex)
        if (tndex&#37;jndex==0){
            sum=sum+jndex;
        }
        if (tndex<sum){
            flag_1=1;
        }

    }//end abbondence check for first num

    return flag_1;
}

void print_if_sum_of_abundants(int n) {
    int i;
    for( i=1;i*2<=n;++i) {
        if(is_abundant(i)&&is_abundant(n-i)) {

            printf("%d=%d+%d\n",n,i,(n-i));
            i=n+1;

        }
    }
}

int main() {
    int limit;
    int i;
    printf("enter number:");
    scanf("%d",&limit);

    for(i=1;i<=limit;++i) {
        print_if_sum_of_abundants(i);
    }
    return 0;
}

Well the first thing you do is go into the editor settings, and set it to "use spaces when I press tab" option, and set it to 4 spaces.

If you only use ALL spaces, or ALL tabs, then the board makes a reasonable job of it.

But as soon as you mix them up (and throw in some couldn't give a damn as well), then it's just a big sorry mess.

Are you certain? This is more of a style question, since it has advantages and disadvantages.
I would just advise to use whatever you feel is best. So long as you do not mix tabs and spaces.

If you have enough tools in your tool chain - edit, compare, print, merge, etc etc, then sooner or later, something will make a complete mess of tabs, especially if you set the width to anything other than the de-facto 8 spaces.

Spaces on the other hand are universal and mean the same everywhere. Proper WYSIWYG.

And causes complete headaches, because IDEs are not smart enough to treat them like tabs.

Use e-macs it does it for you :P

Which IDEs are you using?

Actually, I'm not interested in this x vs. y conversation. If you're using an editor which lacks even basic "smart indent", then you need to find a better editor.

TG2 needs to learn what works, and the magic of the "preview post" button.

As well as many IDEs and editors.
