Write a program to remove line (entered line number) from the file.

#include<stdio.h>
#include<stdlib.h>
#include<string.h>
#include"fileinfo.h"
void Delete_Line_of_File(FILE*,int,char*);
int main()
{
	char fileName[50],ch;

	scanf("%s",fileName);
	fp = fopen(fileName,"r+");
	if(fp == NULL)
	{
		printf("%s File is not present in this directory\n",fileName);
		return 0;
	}
	printf("Which Line Do you want to delete =  ");
	scanf("%d",&DeleteLineOfNumber);
	Delete_Line_of_File(fp,DeleteLineOfNumber,fileName);
	return 0;
}
void Delete_Line_of_File(FILE *fp,int LineNum,char* file)
{
	char **ptr,temp[100];
	int i,LineCount,StrMaxLen;
	LineCount = Get_Total_Lines(fp);
	if(!(LineNum >= 1 && LineNum <= LineCount))
	{
		printf("Invalid Line Number\n");
		fclose(fp);
		return;
	}
	LineNum--;
	ptr = (char**)malloc(sizeof(char*)*LineCount);
	StrMaxLen = Get_Max_String_Length(fp);
	for(i = 0; i < LineCount;i++)
	{
		ptr[i] = (char*)malloc(StrMaxLen+1);
	}
	for(i=0;i < LineCount;i++)
	{
		fgets(ptr[i],StrMaxLen+1,fp);
	}
	fclose(fp);

	}
	fclose(fp);
	printf("Deleting Done....\n");
}
