CLASS NOTES FOR CS 2511

Delimiter = pauses

Why lowercase is different then Uppercase?

·                They have different code.

·                They have different character.

·                A programmer didn’t program it.

ASCII (ASKEY) = Numeric Code

·                A = 65

·                B = 66

·                C = 67

·                D = 68

·                Z = 90

Lowercase a is?

97

How can you solve uppercase, lowercase problem?

Convert it (program it to change cases)

Way to solve a problem is = Algorithm

SEARCH (User needs to create a data.in file)

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

main(){
 char searchname [15], name [15], telephone [14];
 cout << " enter the serch name:";
 cin>> searchname;
 ifstream fin ("data.in");
  while (fin>>name>>telephone){
   if (strcmp(searchname,name)==0){
    cout<<telephone<<endl;
   return  0;
  }//end of if
}//end of loop
cout <<"name not found"<< endl;
return 0;
}//end of main

Function and String is used for the following code!!

#include <fstream.h>
#include<iomanip.h>
#include<string.h>
#include<stdlib.h>

myappend(char personname[],char phone[]){
 ofstream fout("directory.in",ios::app);

 cout<<"ENTER THE SEARCH NAME ";
 cin>>searchname;

  if(strcmp(searchname,personname)==0){
  cout<<"THE PHONE IS "<<phone << endl << endl;
  return 1; }//IF
