ROLL No: 38WAP TO CHECK WHETHER AN INPUT IS A CHARACTER OR A DIGIT

#include <iostream.h>int main(){ char ch; cout<<"Enter a character :"; cin>>ch; if (((ch>='A')&&(ch<='Z'))||((ch>='a')&&(ch<='z'))) cout<<"You entered an alphabet"<<"\n"; else if((ch>='0')&&(ch<='9')) cout<<"You entered a digit"<<"\n"; else cout<<"You entered a character other than"<<"\n"<<" Alpahbets or Digits"; return 0;}

WAP TO PRINT AREA OF A CIRCLE WITH A GIVEN RADIUS

#include <iostream.h>int main(){ int a; cout<<"Enter Radius Of Circle :"; cin>>a; float radius = a; float area; area = 3.14159*radius*radius; cout<<"Area of the circle is :"<<area; return 0;}

WAP TO PRINT ASCII CODE FOR A CHARACTER

#include <iostream.h>int main (){ char ch; cout<<"Enter Alphabet "; cin>>ch; int num=ch; cout<<"The ASCII code for "<<ch<<" is "<<num<<"\n"; cout<<"Adding 1 to the character code\n"; ch=ch+1; num=ch; cout<<"The ASCII code for "<<ch<<" is "<<num<<"\n"; return 0;}

WAP TO PRINT THE CUBE OF A NUMBER (USING FUNCTIONS)
