PROGRAM TO CONVERT CHARACTERS FROM LOWERCASE TO UPPERCASE AND FROM UPPERCASE TO LOWERCASE IN GIVEN STRING IN C++

Write a program to convert all characters from lowercase to uppercase and all upper case characters to lowercase in given string


#include<iostream.h>
#include<conio.h>
void main()
{
 clrscr();
 int m,t=0,i;
 char a[100];
 cout<<"Enter the string\n";
 cin.getline(a,100);
 for(i=0;a[i]!='\0';i++)  //to count total number of words include space
 {
  t++;
 }
 cout<<"\nString after conversion\n";
 for(i=0;i<t;i++)
 {
  m=0;
  m=a[i];
  if(m>=65&&m<=90)
  {
   m=m+32;
   cout<<char(m);
  }
  else
   if(m>=97&&m<=122)
   {
    m=m-32;
    cout<<char(m);
   }
   else
    {
     cout<<char(m);
    }
  }
 getch();
}
