{
int len,asc[20];
char name[20],lo[20]="",up[20]="",rev[20]="";
cout<<"Enter your name:";
cin>>name;
len=strlen(name);
for(int i=0;i asc[i]=toascii(name[i]);
//to lower case
for(i=0;i {
if(toascii(name[i]>96))
lo[i]=name[i];
else
lo[i]=toascii(name[i]+32);
}
//to upper case
for(i=0;i {
if(toascii(name[i]>96))
up[i]=toascii(name[i]-32);
else
up[i]=toascii(name[i]);
}
//reversing
for(i=0;i rev[i]=name[len-i-1];
cout<<"\nname in lower case is "< cout<<"name in upper case is "< cout<<"name in reverse is "< return 0;
}


did each of the 3 three things separately instead of doing it together

make an array of caracters which stores the string caracter
us the for loop to access and edit each carcater..
