Thread: why its not inputting as before..

previoslyi constructed this code for entering an integer array in a row.
it worked fine.
here as it was before:

Code:

 
#include <stdio.h>
int read_array(int input[],int i,int size);
 
int main()
{
	int i;
    int input[40];
    printf("%d\n",read_array(input,0,8));
  for(i=0;i<8;i++)
  {
    printf("%d ",input[i]);
  }
   printf("\n");
}
int read_array(int input[],int i,int size)
{
	int flag,rt;
       
	if (i==size)
	{
     
	   return 1;
	}
     flag=scanf("%d",&input[i]);
	 if (flag==0)
	 {
		 return 0;
	 }
	 else
	 {
	 }
     rt=read_array(input,i+1,size); 
	 return rt;
}

now when i tried to integrate it into the big program
by basicly doing copy paste (in option 3)
it just doesnt work like before
why??

Code:

#include <stdio.h>
int read_array(int input[],int i,int size);
void recSelSort(int array[],int length);
void selSort(int array[], int i ,int length);
void swap(int num[],int i,int j);
int recFindMin(int array[], int index);

 void remove_duplicates(char string[], int index);
void overwrite(char string[], int index);
int has_duplicate(char string[], int index, char ch);


int merge_strings(char str1[], int index1,char str2[],int index2, char result[], int index3);
void read(char input2[],int i);
void main_menu();
void show_menu();
void clean();
int merge(char str1[], int index1,char str2[],int index2, char result[], int index3);
int merge_strings(char str1[], int index1,char str2[],int index2, char result[], int index3);

void main()
{
     main_menu();

}
void main_menu()
{
    //opt1
	int i;
	int size;
    char input[255];
    char input2[255];
    char result[510]={0};
    int flag;
   //opt1


	char opt[900];

   show_menu();

   scanf("%s",opt);

   clean();

   if((opt[0]>='0')&&(opt[0]<='9')&&(opt[1]=='\0'))
   {
       if (opt[0]=='1')
	   
	   if (opt[0]=='2')
	   {
		
	      
	   }
	   if (opt[0]=='3')
	   {
		   printf("Please enter the size of array you want to sort:\n");
		   scanf("%d",&size);
		   clean();
		   printf("Please enter %d values for the array (in one row):\n",size);
		    read_array(input,0,size);
                                      clean();
			for(i=0;i<8;i++)
            {
               printf("%d ",input[i]);
              }
             printf("\n");
			clean();
            
	   }
	   if (opt[0]=='4')
	   {
         printf("4\n");
	   }
	   if (opt[0]=='5')
	   {
         printf("5\n");
	   }
	   if (opt[0]=='0')
	   {
         return;
	   }

   }//end else
   else
   {
       printf("Input incorrect! Please try again.\n");
       printf("\n");
   }
   main_menu();
}
void show_menu()
{
    printf("--------------------------\n");
	printf("Please enter your choice:\n");
    printf("1) Merge strings.\n");
    printf("2) Remove duplicates in the string.\n");
    printf("3) Sort the array using recursive selection sort.\n");
    printf("4) Calculate the length of the max increasing set.\n");
    printf("5) Check partition.\n");
    printf("0) Exit.\n");
 }
void clean()
{
	int lnd;
    lnd= getchar();
     if (lnd != '\n')
	 {
         clean();
	 }
	 else
	 {
          return;
	 }
}


int read_array(int input[],int i,int size)
{
	int flag,rt;
       
	if (i==size)
	{
     
	   return 1;
	}
     flag=scanf("%d",&input[i]);
	 if (flag==0)
	 {
		 return 0;
	 }
	 
     rt=read_array(input,i+1,size); 
	 return rt;
}

it just doesnt work like before

And how exactly it works now? What is the difference?

first fix the following compiler warning (do not ignore those).

warning C4133: 'function' : incompatible types - from 'char [255]' to 'int *'
