any real l33t people wanna check this out for me

im not sure where my bug is but something is acting really weird in here

Code:

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

int main()
{
	char totalcontents[10000]="";
	char FileContents[500], WordToDelete[100], WordToInsert[100], StoreFileContents[500];
	char filename[100];
	cout<<"Enter the name of file: ";
	cin>>filename;	
	cout<<"Enter word to search for: ";
	cin>>WordToDelete;
	cin.ignore(20,'\n');
	cout<<"Enter word to replace it with: ";
	cin.getline(WordToInsert,20);
	fstream file;
	file.open(filename,ios::nocreate|ios::in|ios::out);
	if(file.fail()){
		cout<<"File could not be opened"<<endl;
		return (1);
	}	
	while(file.getline(FileContents,500,'\n'))
	{
		int length1=strlen(FileContents);
		int length2=strlen(WordToDelete);
		int length3=strlen(WordToInsert);
		int count,count2,count3,count4=0,count5=0;
		for(count=0;count<=length1;count++)
		{		
			if(FileContents[count]==WordToDelete[0])
			{
				for(count2=count;count2<=(count+length2);count2++)
				{
					//if(FileContents[count2]!=WordToDelete[count2-count])
					//	break;
					if(count2==(count+length2)){
						strcpy(StoreFileContents,FileContents);
						if(length2==length3)
						{
							for(count3=count;count3<(count+length2);count3++)
							{
								FileContents[count3]=WordToInsert[count3-count];
							}
						}
						else if(length2<length3)
						{	
							for(count3=count;count3<(count+length3);count3++)//replace original
							{
								FileContents[count3]=WordToInsert[count3-count];
							}
							length1=(length3-length2)+length1;
							for(count4=count3;count4<length1;count4++)

							FileContents[length1]=' ';
						}
			
					}
				}
			}		
		}	
	//here we put the thingy back in		
	strcat(totalcontents,FileContents);
	}	
	file.close();
	file.open(filename,ios::trunc|ios::in|ios::out);
	if(file.fail()){
		cout<<"File could not be opened"<<endl;
		return (1);
	}
	file<<totalcontents;
	file.close();
	return (0);

>something is acting really weird in here

What happened when you tested it with what input and what did you expect instead ? We need information to help you.

My guess is that the file contents disappear.. you'll have to put ios::ate alongwith ios:ut.

but as nvoigt said we need more info.

here is an update it working a bit better now yay

Code:

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

int main()
{
	char FileContents[500]="i gotta go to the store gottascape", WordToDelete[100]="gotta", WordToInsert[100]="got to", StoreFileContents[500];
	/*char filename[100];
	cout<<"Enter the name of file: ";
	cin>>filename;	
	cout<<"Enter word to search for: ";
	cin>>WordToDelete;
	cin.ignore(20,'\n');
	cout<<"Enter word to replace it with: ";
	cin.getline(WordToInsert,20);
	*/
		int length1=strlen(FileContents);
		int length2=strlen(WordToDelete);
		int length3=strlen(WordToInsert);
		int count,count2,count3,count4=0,count5=0;
		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)){
						strcpy(StoreFileContents,FileContents);
						if(length2==length3)
						{
							for(count3=count;count3<(count+length2);count3++)
							{
								FileContents[count3]=WordToInsert[count3-count];
							}
						}
						else if(length2<length3)
						{								
							for(count3=count;count3<(count+length3);count3++)//replace original
							{
								FileContents[count3]=WordToInsert[count3-count];
							}
							length1=(length3-length2)+length1;
							for(count4=count3;count4<length1;count4++)
							{
 								FileContents[count4]=StoreFileContents[count4-(length3-length2)];
							}						
						}
						else if(length2>length3)
						{
							for(count3=count;count3<(count+length3);count3++)//replace original
							{
								FileContents[count3]=WordToInsert[count3-count];
							}
							length1=(length3-length2)+length1;
							for(count4=count3;count4<length1;count4++)
							{
 								FileContents[count4]=StoreFileContents[count4+(length2-length3)+1];
							}							
						}
			
					}
					if((FileContents[count2]!=WordToDelete[count2-count])||(FileContents[count+length2]!=' '))
						break;
				}
			}		
		}	
	cout<<FileContents<<endl;
	return (0);
}

ok new problem here i what im trying to do...
i want to replace all occurances of a word in a file with another word...

i need some help on how to replace the stings that im chanign back into the file!

Code:

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

int main()
{
	int numberoflines=0;
	char FileContents[500], WordToDelete[100], WordToInsert[100], StoreFileContents[500], filename[100];;
	cout<<"Enter the name of file: ";
	cin>>filename;	
	cout<<"Enter word to search for: ";
	cin>>WordToDelete;
	cin.ignore(20,'\n');
	cout<<"Enter word to replace it with: ";
	cin.getline(WordToInsert,20);
		
	ifstream file;
	file.open(filename,ios::nocreate);
	if(file.fail()){
		cout<<"File could not be opened"<<endl;
		return (1);
	}

	while(file.getline(FileContents,500,'\n'))
	{	
		numberoflines++;
		int length1=strlen(FileContents);
		int length2=strlen(WordToDelete);
		int length3=strlen(WordToInsert);
		int count,count2,count3,count4=0,count5=0, count6=0;		
		for(count=0;count<=length1;count++)
		{		
			if(FileContents[count]==WordToDelete[0])
			{
				for(count2=count;count2<=(count+length2);count2++)
				{
					if((count2-count)==(length2)){
						strcpy(StoreFileContents,FileContents);
						if(length2==length3)
						{
							for(count3=count;count3<(count+length2);count3++)
							{
								FileContents[count3]=WordToInsert[count3-count];
							}
						}
						else if(length2<length3)
						{								
							for(count3=count;count3<(count+length3);count3++)//replace original
							{
								FileContents[count3]=WordToInsert[count3-count];
							}
							length1=(length3-length2)+length1;
							for(count4=count3;count4<length1;count4++)
							{
  								FileContents[count4]=StoreFileContents[count4-(length3-length2)];
							}						
						}
						else if(length2>length3)
						{
							count6++;
							for(count3=count;count3<(count+length3);count3++)//replace original
							{
								FileContents[count3]=WordToInsert[count3-count];
							}
							length1=(length3-length2)+length1;
							for(count4=count3;count4<length1;count4++)
							{
  								FileContents[count4]=StoreFileContents[count4+(length2-length3)];
							}
							for(count4;count4<((length2-length3)+length1);count4++)
							{
								FileContents[count4]=' ';
							}
						}
			
					}
 					if((FileContents[count2]!=WordToDelete[count2-count])||((FileContents[count+length2]!=' ')&&(FileContents[count+length2]!='.')))
						break;
				}
			}		
		}
		for(count3=0;count3<length1;count3++)
		{
			cout<<FileContents[count3];
		}
		cout<<endl;
	}
	file.close();
	return (0);
}

You have the whole file stored in FileContents right? So why don't you just rewrite the whole file from your updated string using ios::trunc (Although technically by putting ios:ut it implies ios::trunc)?
