//Progrma to toggle case of every alphabet

#include<iostream.h>
#include<conio.h>
#include<ctype.h>
char string(char []);            //function prototype to toggle the case of string
main()
{
char a[50];
gets(a);
fflush(stdin);
char (*Toggler)(char []);         //function to pointer
Toggler=string;                   //assigning the address of function to pointer
string(a);                        //calling function
cout<<"String after toogling :"<<Toggler;
getch();
}
char string(char a[])           //function defination to toggle the case of string
{
for(int i=0;a[i]!='\0';i++)
{
if(isupper(a[i]))                //changing the case
{
                 a[i]=tolower(a[i]);
}

{
     a[i]=toupper(a[i]);
}
