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[count4]=StoreFileContents[count4-1]; } } 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+1]; } 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); }

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::out.

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::out it implies ios::trunc)?
