#include<stdio. h>
int main()
{ int n,i,j=0;
char a[n],c[n];
char b;
scanf("%d",&n);
scanf("%s",a);
scanf("%c",&b);
for(i=0;i<n;i++ )
{
if(a[i]!=b)
{
c[j]=a[i];
j++;
}
}
printf("%s",c);
}

Please explain a little more. I'm not sure exactly what you want to do.

I'm surprised you don't get compiler errors for declaring arrays a and c with size equal to uninitialized variable n.
How do you know the user will enter a value for n that is less than or equal to the length of the string that is entered for a?
How certain are you that you write a terminating null to array c?
