Facing an issue while writing program for duplicate occurrence of a character in a string, can any one help?

Question

#include<stdio.h>
#include<string.h>
main()
{
    char p[100];
    int i,len;
    printf("Enter a string\n");
    scanf("%[^\n]",p);
    len=strlen(p);
    for(i=0;i<len-1;i++)
    {
        if(a[i]==a[i+1])
              p[i]=p[i+1];
    }
    printf("String :  %s\n",p);
}
