transforming code to one main function..

[transgalactic2]

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
??

#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

#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;

} 
  }
