Program in C to delete a Character from a given position in a given string Using Function

First Method

#include<stdio.h>
#include<string.h>
  char* Delete(char str[],int p)
    {
     int i;
     for(i=p-1;i<strlen(str);i++)
       str[i]=str[i+1];
  return str;  
 }
 int main()
  {
   char str[100],*str1;
 int position;
   printf("Enter a string:-");
   scanf("%s",str);
   printf("Enter the position from where you want to delete a character:-");
        scanf("%d",&position);
        printf("Before deletion  = %s\n",str);
   str1=Delete(str,position);//Here str passing call by reference. Then any changes made inside the Delete function it is also reflected in main Function.
       printf("After deletion  = %s\n",str1);//In deletion operation 
     return 0;
  }
