Here is the C Program to generate a series which leads us to understand the number of zeros in a Factorial: -------------------------------------------------------------------------------------------------------------------------- #include <stdio.h> #include<stdlib.h> int ZerorsInFactorial(int number); int main(int argc, char **argv) { //printf("hello world\n"); //This is to see the howmany zeros will be there in a factorial , let that be P. //The values P take as we move towards infinity int i=0;FILE *fptr; fptr=fopen("program.txt","w"); if(fptr==NULL){ printf("Error!"); exit(1); } while(i<1000) { fprintf(fptr,"%d zeros in %d factorial\n",ZerosInFactorial(i),i); printf("%d zeros in %d factorial\n",ZerosInFactorial(i),i);i++; } fclose(fptr); // printf("Hello World"); return 0; } int ZerosInFactorial(int n
