heres the code

#include <iostream.h>
#include <fstream.h>
#include <string.h>

int main()
{
	char FileContents[500]="three blind mice three blind mice three blind mice", WordToDelete[10]="three", WordToInsert[10]="weirdos";
	char StoreFileContents[500]="three blind mice three blind mice three blind mice";
	int length1=strlen(FileContents);
	int length2=strlen(WordToDelete);
	int length3=strlen(WordToInsert);
	int count,count2,count3;
	cout<<FileContents<<endl;
	for(count=0;count<=length1;count++)
	{		
		if(FileContents[count]==WordToDelete[0])
		{
			for(count2=count;count2<=(count+length2);count2++)
			{
				if(count2==(count+length2))
					if(length2==length3)
					{
						for(count3=count;count3<(count+length2);count3++)
						{
							FileContents[count3]=WordToInsert[count3-count];
						}
					}
					else if(length2<length3)
					{
						//count is location of first letter of the word to remove
						for(count3=count;count3<=(count+length3);count3++)
							FileContents[count3]=WordToInsert[count3-count];
						for(count3=count;count3<=length1;count3++)
							FileContents[count3+length3+(length3-length2)]=StoreFileContents[count3+length2];						
					}
			}
		}
	}
	cout<<endl;
	for(count=0;count<=length1;count++)
		cout<<FileContents[count];
	cout<<endl;
	cout<<FileContents[20];
	return (0);
}

i just skimed you code, but it looks like you're not making up for the difference in word lenths between three and weridos. i think you have to push the entire array back one char for each replacement yiou try. or you can just make the replacement the same length as the replaced. good luck
